7. Transmitting a Signal
To transmit a signal, press the Push-To-
Talk (PTT) key on the side of the radio.
While transmitting, the
TX indicator will
appear (Fig. 6a). When the PTT key is
released, the radio will return to Receive
Mode.
• You cannot transmit on receive-only
channels like the Weather Channels
or Channels 15 and 70. If you try, an
error tone will sound, the Channel
Number and TX indicators will blink
three times, and then go back to the
normal display (Fig. 6b).
• If the PTT key is pressed when the
battery condition is low, one last
transmission will be allowed, then an
error tone will sound with
BAT LO
displayed. No further transmission
will be allowed.
8. Selecting the Transmit
Power
To change the transmit power, press and
hold the H/L key for over two seconds
(Fig. 7a, 7b).
Restricted Channels
Certain channels are limited by law to 1
watt transmit power (USA Mode Channel
12, 17, 67, 77; INT Mode Channel 15, 17,
CAN Mode Channel 12, 15, 17, 20, 66,
77). These channels will always transmit
on low (1 watt) power.
• You cannot change the transmit
power setting on receive-only chan-
nels (all weather channels, USA
Mode Channel 15, 70, INT Mode
Channel 70, CAN Mode Channel 70)
• If you press the H/L key while scan-
ning or while on a receive-only chan-
nel, the error tone will sound and the
transmit power setting will not
change.
