4 Manual Offset Selection

The factory default sets the automatic offset frequency. You can select any offset frequency in the range 0 to 99.9 MHz in 100 kHz steps.

1Press and hold the SHIFT/REV key and switch the power on.

2Press the F key for longer than one second, then press the SHIFT/REV key.

The current offset frequency is shown on the LCD.

3Rotate the Tuning control, and select the desired offset frequency.

4Press any front panel key to return to the normal frequency display.

To return to the normal offset, reset the VFO. (see page 19)

Note

Selecting an offset frequency that would result in the radio transmitting outside its intended range will cause an error tone to be sounded and transmit to be inhibited. Reselect a valid offset frequency if this occurs.

5 The Reverse Function

Some repeaters use a ’ reverse pair’, that is, the transmit/receive frequencies are the reverse of other repeaters.

For example, repeater A uses 146.000 as an input frequency, and 146.600 as an output frequency. Repeater B might use 146.600 as an input frequency, and 146.000 as an output frequency. It would be quite inconvenient to have to reprogram the transceiver each time you want to use these repeaters.

Press the F key, then press the SHIFT/REV key. The R indicator displays to remind you that you are working a reverse pair.

Press the F key, then press the SHIFT/REV key again to return to normal. The R indicator will disappear.

This function is also useful in checking the repeater input frequency, allowing you to determine if you are in range for simplex communication.
