You can select the desired transmitter offset by
repeatedly pressing the OFFSET key. The display will
indicate which offset has been selected by turning
on a small bar under the selected offset. In simplex
mode no bar will show under the +" or "—""

sion).
4-6-2. REV (Reverse) feature
The REV switch reverses the transmit and receive
frequencies when using an OFFSET or split frequen-
cy memory {channel 9 or 0).
This function is used to check the repeater's input
frequency or operate on reverse repeater {Pairs the
input/output frequencies are opposite to those of a
normal repeater).
Operation
To use the REVERSE function press the REV key.
The REV indicator in the display will illuminate and
the displayed frequency will change to the old
transmit frequency. The radio will now transmit on
the old receive frequency when the PTT switch is
depressed.
Note (TR-751A/751E only):
To use the F.STEP function press the F.STEP key
before pressing the REV key.
If the F.STEP key is activated while in the REV mode
the radio will revert back to the original receive fre-
quency. You can cancel this by turning the TUNING
knob or pressing the PTT switch.
