Fig 3-5 Indications for Transmit, Receive and Guard Operation
When entering data using the keypad, each button cycles through the associated characters.
For example button 2 cycles through: a b c A B C 2. When a different button is pressed, the
last character selected is accepted and the new button is treated as the next character.
If two sequential characters from the same button are required, the Arrow keys (Key 7 and
Key 8) must be used to position the cursor in the required position.
Key 7 and Key 8 move the data entry cursor left and right respectively.
The Arrow key function is displayed only when a data entry is required.
Rx is displayed when a signal, strong enough
to lift the squelch, is received.
Rx (d) is displayed when the receiver’s
squelch is defeated (the RX button toggles
Squelch Defeat on and off).

Press to defeat guard squelch. Press again to
enable squelch operation.

selected frequency/channel.
