© VFO key
This key is used to return to VFO operation after operat­
ing in the MR or CALL channel mode. Pressing this switch
will allow the tuning control and microphone UP/DWN
keys to increase or decrease the operating frequency.
Press and hold the key for longer than 1 second to initi­
ate VFO scan. Pressing the key after scan has been in­
itiated will cause scan to stop.
Pressing the key within 10 seconds of pressing the F key
will copy the memory channel or call channel data to the
VFO. This allows you to change parameters of that chan­
nel without actually changing the data that has been
stored in memory.
Pressing the F key for longer than 1 second and then
pressing the VFO key will cause radio to toggle the
hold/resume mode between Time Operated scan and Car­
rier Operated scan.
If you press and hold the VFO key while you turn on the
POWER switch you will reset the microprocessor's VFO
memory, without destroying the memory channel or call
channel data.
@ MR key
This key is used to select MR (Memory Recall) mode from
the VFO mode. The tuning control can then be used to
select the desired Memory channel.
Pressing the key for longer than 1 second will initiate
memory channel scanning.
Pressing the key within 10 seconds of pressing the F key
will store the displayed data into memory.
In the MR channel mode pressing the F key for longer
than 1 second and then pressing the MR key will cause
the Memory channel to skip during Memory channel scan
mode.
If you hold and press this key while you turn on the POW­
ER switch you will clear all the microprocessor's, opera­
tor programmed, memory section.
@ MHz key
This key is used to tell the microprocessor that you wish
to increase or decrease the operating frequency in 1 MHz
increments.
Pressing this key within 10 seconds of pressing the F key
will cause the key lock function to activate, protecting
the currently displayed data from accidental erasure.
