FIRST TIME INSTALL / POWER UP

The first time the HR2510/HR2600/LINCOLN is powered up, after the CHIPSWITCH has been installed, you will be required to enter the type of radio you are using. The radio will display "HR2510" as the first choice, "HR2600" as the second choice and "LINCOLN" as the third. Press the Span button until the type of radio you have is displayed on the readout. Then press the Band button to enter that selection into the microcomputer's memory. You are only required to do this when the CHIPSWITCH is installed into your radio for the first time, or if you issue a MASTER RESET command.

Note: If your radio is turned off for an extended period, or if a severe electrical disturbance (sparking wires, shorts, etc.) Is caused on the power supply to the radio, the internal memory inside the microcomputer chip may 'forget' what you have programmed into it. If this should happen, your radio will display 'HR2510' and you will need to re-program it just as you did when the chip was first installed. Also, a severe electrical disturbance may cause your radio's memory to become 'confused', causing improper frequencies or strange character to be displayed on the readout. If this should happen, invoke a MASTER RESET function and then re-program the radio.

OPERATIONS

ENABLE/DISABLE FUNCTIONS

While the HR2510/HR2600/LINCOLN is in OPERATE MODE, you can enable or disable any of the radio's major functions from the front panel. Some of these functions are not operational in specific "BANDS." The display segment before the frequency readout indicates which function is enabled. (See below)

NOTE: (1) This function will only work if PRIORITY CHANNEL frequency is not programmed.
 (2) This function will only work if PRIORITY CHANNEL frequency is programmed.
 (3) On the LINCOLN radio, use INDICATOR instead of METER.

PROGRAM MODE

This function enables you to program the new CHIPSWITCH features on the HR2510/HR2600/LINCOLN.
           Step 1. Press the F.lock button in
           Step 2. Press the Meter (INDICATOR for the LINCOLN) and CHAN UP buttons simultaneously

The radio notifies you that you are in PROGRAM MODE with "4 beeps" and a 'P' displayed in the Band indicator. At this point, you can program any of the 46 FEATURES outlined in the PROGRAMMING section of this manual.

MEMORY CHANNEL TEMPORARY LOCKOUT

This enables you to temporarily lockout any user-programmed frequency(s) for SCAN and SEEK functions. To enable or disable this toggle function:

Step 1. Assuming frequencies were programmed into any memory group, go to any MEMORY BAND (Band 1, 2 or 3) where you wish to scan or seek
Step 2. Choose the frequency(s) you wish to lockout temporarily using the CHAN UP or CHAN DN buttons
Step 3. Press the F.lock button in
Step 4. Press Span and CHAN DN buttons simultaneously (Top bar indicator comes on)
Step 5. Release the F.lock button
Step 6 Start the SCAN or SEEK function

At this point the frequency(s) that were "locked-out" will not be included when you perform the SCAN or SEEK function on that MEMORY GROUP.

SCAN LIMITS ON/OFF

This toggle function allows you to enable or disable the SCAN and SEEK frequency limits for Band 0. If this toggle function is enabled, and a lower and an upper frequency limit is programmed in FEATURE 3 and 4, the radio will scan or seek only between these frequencies. To enable and use this feature:

Step 1. You must be in Band 0 and have FEATURE 3 and 4 programmed with the limits
Step 2. Press the F.lock button in
Step 3. Press the Band and Span buttons simultaneously (Bottom bar indicator comes on)
Step 4. Release the F.lock
Step 5. Press the Scan button

At this point the radio will either SCAN or SEEK depending on the value programmed in FEATURE 5. If a scan value (0-3) is programmed in FEATURE 5, the scan hold time rate will be determined by FEATURE 6. Squelch must be closed for the SCAN function to work properly. If a seek value (4-7) is programmed in FEATURE 5, the seek hold time will be determined by FEATURE 7.

SCAN and SEEK also functions in BAND 1, 2 and 3. The difference being that in these memory bands, you either scan or seek through the MEMORY CHANNELS previously programmed in these MEMORY BANDS.

SPLIT FREQUENCY OPERATIONS ON/OFF

This toggle function allows you to transmit on one frequency while receiving on another. Split Frequency is only available in Band 0. To enable and use this function:

Step 1. Go into PROGRAM MODE
Step 2. Go to FEATURE 1 and enter a value for your TX/RX offset (000.1 - 999.9)
Step 3. Go to FEATURE 2 and choose whether the offset will be positive (1) or negative (0)
Step 4. Exit PROGRAM MODE (Now you must be in Band 0)
Step 5. Press the F.lock button in
Step 6. Press BAND and CHAN DN buttons simultaneously. Either an "H" or "L" indicator will come                                up depending on the value programmed in FEATURE 2.
Step 7. Release the F.lock button
Step 8. Choose a receive frequency

At this point you are ready to communicate in SPLIT FREQUENCY mode.

OPERATING IN SPLIT FREQUENCY MODE

To use this function reliably, the two parties involved in the QSO must be versed on operating split channels. Two users are mentioned in the explanation below, OPERATOR A and OPERATOR B, to better understand the procedures.

Step 1. OP A and OP B must have the SAME offset programmed in Feature 1
Step 2. OP A and OP B must have OPPOSITE polarity programmed in Feature 2
Step 3. OP A chooses his receive frequency using the VFO, CHAN UP/DN or MIC UP/DN buttons
Step 4. OP B moves to his receive frequency, which is OP A's transmit frequency, using the VFO, CHAN UP/DN or MIC UP/DN buttons

Note: OP B's receive frequency = (OP A's receive frequency) + or -(offset in Feature 1) The + or - is determined by OP A's polarity in Feature 2.

Step 5. OP A and OP B enables SPLIT FREQUENCY OPERATIONS
Step 6. START COMMUNICATION

SPLIT FREQUENCY POLARITY CHANGE

The SPLIT FREQUENCY POLARITY is initially programmed in the PROGRAM MODE. In some instances, you may wish to change polarity without having to go into Program mode. To use this feature:

Step 1. Press F.lock button in
Step 2. Press Scan and CHAN UP buttons simultaneously
Step 3. Release the F.lock button

Note: This toggle function will only work if PRIORITY CHANNEL frequency is not programmed. This is because the same buttons are used for both, and PRIORITY CHANNEL ON / OFF function has precedence.

PRIORITY CHANNEL ON/OFF (REQUIRES ADDITIONAL HARDWARE)

This function, when enabled, allows you to continuously monitor one frequency while operating on another. To enable this function:

Step 1. Go into PROGRAM MODE
Step 2. Enter a frequency in FEATURE 44
Step 3. Exit PROGRAM MODE
Step 4. Press the F.lock button in
Step 5. Press the Scan and CHAN UP buttons simultaneously
Step 6. Release the F.lock button

PRIORITY CHANNEL CHECK & LOCK

FEATURE 45 allows you to select PRIORITY CHANNEL functionality. If you choose a value between 0 and 3, the priority channel selected in FEATURE 44 will be checked and the radio "beeps" to notify you of any activity on that channel. This feature only notifies you of activity on the priority channel. To lock on to the priority channel, you will have to:

Step 1. Press the F.lock button in
Step 2. Press Scan and METER (INDICATOR for the LINCOLN)
Step 3. Release the F.lock button

If you choose a value between 4 and 7, the priority channel will be checked for activity. If the squelch is broken, the radio will "lock" on to the priority channel and remain there until the activity ceases. To keep the radio from returning to the original operating frequency when activity ceases on the priority channel, press the F.lock button in.

MASTER RESET

Step 1. Power off the radio
Step 2. Press the F.lock button in
Step 3. Press and hold the SCAN and METER (INDICATOR for the LINCOLN) and turn the radio on all at the same time

This FUNCTION erases all user programmed values and installs the factory default values. This FUNCTION also brings the radio to a "First-Time Install" state.

USING SPLIT CHANNEL with PRIORITY CHANNEL FUNCTION

If both the SPLIT FREQUENCY OPERATIONS and PRIORITY CHANNEL functions are enabled, the SPLIT FREQUENCY OFFSET CHANGE function is disabled because, the same set of keys is used to enable the PRIORITY CHANNEL function. With the squelch closed, the SPLIT FREQUENCY OPERATIONS will function as it should. As soon as the priority channel squelch is broken, the radio will switch to the priority channel. If you lock on to the priority channel and transmit at this time, both the SPLIT FREQUENCY OPERATIONS and PRIORITY CHANNEL functions will be disabled, and you will be transmitting on the priority channel.

OPERATE MODE

While in the OPERATE MODE, all original radio functions and buttons work as they did before EXCEPT for the following:

BANDS: (Selected by pushing the BAND Button)

FREQUENCY BAND (0)

This is the entire tuning range of the HR2510/HR2600/LINCOLN. Some user defined functions in PROGRAM MODE are available only on this band (i.e., SCAN/SEEK LIMITS, SPLIT FREQUENCY OPERATION). The radio's Channel UP/DN and the Microphone UP/DN buttons control any frequency change as selected in the PROGRAM MODE features 8 and 9. The radio's VFO knob works as before.

MEMORY GROUP 1 (1)

A maximum of 10 frequencies can be stored in this memory group. In this band, channel numbers (0 - 9) appear on the display with the user-programmed frequencies. A minus (-) 100 kHz REPEATER OFFSET can be selected on a channel-by-channel basis in the PROGRAM MODE. This is indicated by the blinking 10MHz segment of the front panel display. Frequencies/channels previously programmed can be temporarily locked-out from the SCAN/SEEK function using the MEMORY LOCKOUT FUNCTION.

MEMORY GROUP 2 (2)

This is the second group of memory channels and is operationally identical to MEMORY GROUP 1 (1).

MEMORY GROUP 3 (3)

This is the third group of memory channels and is operationally identical to MEMORY GROUP 1 (1) and MEMORY GROUP 2 (2) EXCEPT this band operates on a PLUS (+) 100 KHZ REPEATER OFFSET if this option is chosen in the PROGRAM MODE.

SCAN, CHANNEL UP/DN, AND MIC UP/DN

These functions are user-programmable in the PROGRAM MODE.

LOCAL BEEP TONE

The local beep tone can now be disabled or programmed from 1/20^th second "click" to a second-long tone.

PROGRAM MODE

Most of the features have been pre-programmed from the factory and will have default values stored in memory. You will have to determine which features (detailed in the next section) you wish to change.

To enter PROGRAM MODE:

Step 1. Press the F.lock button in
Step 2. Press the CHANNEL UP and METER buttons simultaneously

When the HR2510/HR2600/LINCOLN goes into PROGRAM MODE you are notified by "4 - beeps" and the BAND indicator will display a "P" indicating the radio is in PROGRAM MODE. In this mode, the METER display (RF, MOD, ^, SWR) will be blank. The CHANNEL NUMBER display will show "0" indicating the first enhanced FEATURE (BEEP ON-TIME) programmable by you. The FREQUENCY display will have the right-most digit (100Hz) illuminated with the default value for this FEATURE.

You can review / change the values of any of the 46 FEATURES using the CHANNEL UP/DN buttons and VFO knob of the radio. The Channel Up/Dn buttons select which FEATURE, and the VFO KNOB changes the VALUE of that feature.

CAUTION: Leave the F.lock button depressed to prevent accidental programming if you are just going to view the programmable features. If you plan to change the value for a particular FEATURE, the F.lock button must be in the "out" position for the VFO knob to work.

To exit the PROGRAM MODE:

Step 1. Press the F.lock button in
Step 2. Press the CHANNEL UP and METER buttons simultaneously
The radio will "beep" once and return to the OPERATE MODE.

PROGRAMMING

Following is a detailed explanation of all the PROGRAMMABLE FEATURES and how you can program each individual FEATURE:

NOTE: SCAN/SEEK by these limits is only functional in Band 0. If no values are entered in feature 3 and feature 4, the radio's lowest and highest operational limits are used as defaults during SCAN/SEEK.

 NOTE: To use the automatic minus (-) 100KHz repeater offset under MEMORY GROUP 1 and 2, press the SCAN button after entering the frequency. The 10MHz digit will blink to indicate that this channel has been programmed to use the OFFSET option. To disable, press the SCAN button again.

NOTE: To use the automatic plus (+) 100KHz repeater offset under MEMORY GROUP 3, press the SCAN button after entering the frequency. The 10MHz digit will blink to indicate that this channel has been programmed to use the OFFSET option. To disable, press the SCAN button again.

Any memory channel with a frequency of 00.000.0 is un-programmed and will be skipped during the OPERATE MODE. To erase a frequency from any MEMORY GROUP, ensure the F.lock button is out, then press the BAND button to set the frequency to 00.000.0.

NOTE: REQUIRES ADDITIONAL HARDWARE TO FUNCTION PROPERLY

NOTES:
(DEF) = The first time the CHIPSWITCH is installed on the HR2510/HR2600/LINCOLN, these are the values that will be displayed upon entering PROGRAM MODE.

Any frequency type feature may be erased in program mode by pressing the BAND button with the F.Lock button out.

SERIAL NUMBER DISPLAY

To display the SERIAL NUMBER of the CHIPSWITCH IC, perform the following:

1. Prepare to enter PROGRAM MODE. Hold the microphone in one hand and prepare the other hand to press the buttons necessary to enter the PROGRAM mode.
2. Press the buttons necessary to enter PROGRAM MODE. AFTER the first of the 4 'beeps', but BEFORE the end of the 4^th 'beep', press in the microphone's PTT (transmit) button.
3. The chip's serial number will now be displayed for as long as you keep holding in the microphone's PTT button.

Note: This is useful in case you ever need to know the chip's serial number but didn't write it down.

ERROR MESSAGES

If the HR2510/HR2600/LINCOLN detects an error with any of the programmed data, or during OPERATE MODE, an ERROR CODE will be displayed on the frequency display. The format of the ERROR CODE is as follows:

"Err X"

where X is:

0 = Transmitter Timeout timer has timed-out
1 = Transmit Frequency is lower than TX Lockout Lower Limit (programmed)
2 = Transmit Frequency is greater than TX Lockout Higher Limit
3 = Phase-locked-loop (PLL) won't lock at this transmit frequency
4 = PLL is intermittently coming out of lock during transmit

If your radio displays error 3 or 4, don't keep trying to transmit on this frequency. The cause of the problem could be low power supply voltage to the radio or the radio's VCO loop needs adjustment. Refer to a qualified technician for service. Contact the installer of the chip first.
