OPERATING THE TRANSMITTER

Keying the microphone push-to-talk button will
switch the transmitter circuits on, indicated by
the 'TX' indicator appearing on the display.
Speak in a normal voice with your lips about
one eighth of an inch away from the
microphone. Do not shout. Shouting reduces
intelligibility.
If regulations prohibit 25 watts of power on a given channel, the power level
cannot be changed. No power level selection is allowed on receive only
channels (e.g. WX channels).
US channels 13, 67, and 77 can be operated at full power by pressing the
key during transmission. Releasing the key will return the radio to 1 watt
operation.
A time out timer is provided to prevent continuous transmissions for periods
greater than 5 minutes. In the event that the radio will be needed to transmit for
periods longer than 5 minutes, it will be necessary to release the PTT briefly
before the 5 minute timer expires.
