BASIC OPERATION 3 When diversity operation is in use, connect the same type antenna to both [ANT1] and [ANT2 RX]. ➥ During single band operation with the diversity function ON, the diversity indicator appears as below. Diversity indicator appears. While [ANT2 RX] is selected; While [ANT1 TX/RX] is selected; When a frequency band that the diversity reception is inhibited is selected. With the squelch open in FM mode while receiving a weak signal, diversity receiving does not work properly. ■ One-touch PTT function 1 The PTT switch can be operated as a one-touch PTT switch 2 (each push toggles between transmit/receive). Using this function you can transmit without pushing and holding the 3 PTT switch. 4 To prevent accidental, continuous transmissions with this 5 function, the transceiver has a time-out timer. See p. 101 for 6 details. 7 z Push [FUNC] then [PRIO 3(PTT-M)] to turn the PTT-M one-touch PTT function ON. 8 • The activity indicator lights green. 9 x Push [PTT] to transmit and push again to receive. 10 • A beep sounds when transmission is started and a 11 long beep sounds when returning to receive. c Push [FUNC] then [PRIO 3(PTT-M)] to turn the 12 one-touch PTT function OFF. 13 • The activity indicator goes out. 14 15 16 17 18 19 26

During single band operation with the diversity function ON,
the diversity indicator appears as below.
With the squelch open in FM mode while receiving a weak
signal, diversity receiving does not work properly.

One-touch PTT function
The PTT switch can be operated as a one-touch PTT switch
(each push toggles between transmit/receive). Using this
function you can transmit without pushing and holding the
PTT switch.
To prevent accidental, continuous transmissions with this
function, the transceiver has a time-out timer. See p. 101 for
details.

one-touch PTT function ON.
• The activity indicator lights green.
x
Push [PTT] to transmit and push again to re-
ceive.
• A beep sounds when transmission is started and a
long beep sounds when returning to receive.
c
Push [FUNC] then [
PRIO
3(PTT-M)] to turn the
one-touch PTT function OFF.
• The activity indicator goes out.
PTT-M
Diversity indicator appears.
While [ANT2 RX] is selected;
While [ANT1 TX/RX] is selected;
When a frequency band that the diversi-
ty reception is inhibited is selected.
