4 Manual Offset Selection 5 The Reverse FunctionThe factory default sets the automatic offsetfrequency. You can select any offset frequency inthe range 0 to 99.9 MHz in 100 kHz steps.Some repeaters use a ’ reverse pair’, that is, thetransmit/receive frequencies are the reverse of otherrepeaters.1 Press and hold the SHIFT/REV key and switch thepower on.2 Press the F key for longer than one second, thenpress the SHIFT/REV key.The current offset frequency is shown on the LCD.For example, repeater A uses 146.000 as an inputfrequency, and 146.600 as an output frequency.Repeater B might use 146.600 as an input3 Rotate the Tuning control, and select the desiredoffset frequency.frequency, and 146.000 as an output frequency. Itwould be quite inconvenient to have to reprogram thetransceiver each time you want to use theserepeaters.4 Press any front panel key to return to the normalfrequency display.Press the F key, then press the SHIFT/REV key.The R indicator displays to remind you that you areworking a reverse pair.To return to the normal offset, reset the VFO.(see page 19)NoteSelecting an offset frequency that would result inthe radio transmitting outside its intended rangewill cause an error tone to be sounded andtransmit to be inhibited. Reselect a valid offsetfrequency if this occurs.Press the F key, then press the SHIFT/REV keyagain to return to normal. The R indicator willdisappear.This function is also useful in checking the repeaterinput frequency, allowing you to determine if you arein range for simplex communication.30
