Dual; Flip Flop Button - XCOM 760 Installation And User Manual

memory channels are displayed as channel number on the bottom line and
frequency on the top. Use the F/CH control to scroll through the memory channels.
Only channels that are programmed will be displayed. If you wish to load the
memory frequency to the main flip flop screen for either using later to transmit on,
or to dual monitor, simply press and hold in the for 2 seconds, this will transfer
the currently displayed memory channel to the flip flop screen and return you to
the flip flop screen. If you press it only once (do not hold in for longer than a
second) the screen will revert back to the main screen (flip flop) with no memory
channel loaded.
Press the MEM button twice to access the NOAA weather channels, use the F/CH
control to scroll through the weather channels. Hit the to select this option and
return to the main screen.
Dual - Press this button when in the main screen (flip flop). The DUAL WATCH icon
will be illuminated. Both the active and the standby frequencies are now being
monitored. The active is always considered the priority frequency and the standby
the secondary frequency. Whilst listening to the active frequency the transceiver
checks the standby 4 times a second for activity, if there is activity then it locks on
to the standby and stays there for the duration of the transmission on the standby
frequency unless there is a transmission on the active frequency. If there is a
transmission on the active frequency the transceiver will stay there only returning
to scanning on dual watch 5 seconds after voice transmission has ceased. If you
press the PTT button you will only transmit on the active frequency while in dual
watch, the dual watch feature will temporarily switch off for about 5 seconds when
you transmit expecting a reply to come back from another aircraft or ATC, if no
reply comes back then the transceiver will return to scanning again.
Note: When there is a station talking on the standby frequency a slight PIP PIP
sound may be heard, this is the scanning sound as the transceiver momentarily
checks the active frequency, this sound is normal in this mode.
If the active frequency is receiving the RX icon will be illuminated, and the –
between the MHz and KHz on the active frequency display will blink (top line
display), this indicates that the active is receiving. If the standby is receiving then
the RX icon will be illuminated and the – between the MHz and KHz will blink on the
standby frequency (bottom line display), this indicates that the standby frequency
is receiving.

Flip Flop button

- Pressing this in the main screen (flip flop screen) will transfer
the top line to the bottom, and the bottom to the top. When in MEM mode, pressing
and holding it down for 2 SECONDS will transfer the currently displayed MEM
channel to the standby screen in the main screen (flip flop screen). When in MEM
mode pressing it for 1 second will revert back to main screen. When in MODE
screens, hitting the button will either enter and return or just return back to the
main screen.
