5.0 OPERATIONAL MODES
The M760 transceiver can operate in several operation modes. The user can step through these modes by
pressing the mode switch briefly. Operational modes are:
Active/Standby Mode
Channel Mode
VOX Adjust Mode
5.1 ACTIVE/STANDBY MODE
The display shows the active or in use frequency on the top line. The standby frequency is displayed on
the bottom line. Only signals on the active frequency are received. Transmissions can be made on the
active frequency by pressing the PTT button.
The active and standby frequencies are swapped by
pressing the remote memory button or the toggle switch.
The standby frequency can be changed by scrolling the
frequency adjust knob. The cursor can be moved between
MHZ and KHZ positions by pressing the frequency adjust
knob. Press the mode switch to toggle the display from
Active/Standby mode to Memory mode.
5.1.1 108 TO 118 MHZ TUNING
The pilot can select channels in the navigation (NAV) band from 108.000MHz to 117.975 MHz. The
M760 will receive only on these channels – the PTT button is disabled.
Many civil aviation authorities are now allocating voice services such as ATIS in the NAV band.
IMPORTANT NOTE
When the active frequency is set below 118.000MHz, the
transmitter is disabled.
