12. COMM FREQUENCY TRANSFER BUTTON ( tE •
) --
Interchanges the frequencies in the USE and STANDBY
displays. To tune the radio to the desired operating frequency,
the desired frequency must be entered into the standby
display and then the transfer button must be pushed. This will
trade the contents of the active and standby displays. The
operating frequency can also be entered by accessing the
ACTIVE ENTRY (direct tune) mode which is done by pushing
the
COMM
TRANSFER button for 2 or more seconds. In the
direct tune mode, only the active part of the display is visible.
The desired frequency can be directly entered into the display.
Push the COMM TRANSFER button again to return to the
active/standby display.
The transceiver is always tuned to the frequency appearing in
the ACTIVE display. It is, therefore, possible to have two
different frequencies stored in the ACTIVE and STANDBY
displays and to change back and forth between them at the
simple push of the transfer button.
