Basic Operating Instructions
Transmit
In the United States, FCC regulations require you to monitor the channel before you
transmit. Refer to the Programmable Options section of this manual for Monitor
instructions.

The transmit icon lights on the display during transmission. The LED on the
microphone also glows red while you are transmitting.
2
Hold the microphone 2-3 inches (5-8 cm) away from your mouth while
NOTE:
speaking clearly into it.
Do not transmit when a person is within 2 feet (0.6 meter) of the antenna unless that
person is shielded from the antenna by a metal surface such as the roof of the car.
NOTE:
Monitor On-Off/Volume Set
Monitor/VolumeSet allows you to monitor the channel for activity when PL is
enabled (same as taking the microphone off hook) or to set the volume.
To Monitor
In the United States, FCC regulations require you to monitor the channel before you
transmit. Although all countries do not have a similar requirement, monitoring the
channel is proper radio etiquette to provide an orderly approach to using shared frequencies.

Standard Programmable Features
Time-Out Timer (T.O.T.)
Limits the amount of time you have to transmit. Preprogrammed from
1 to 255 seconds or off.
When you reach the time limit, a continuous, low-pitched tone sounds (until
you release the PTT) and your transmission is cut off.
Busy Channel Lockout
Several groups of radio users may share a channel. Busy channel lockout
monitors channel activity for you (even activity you cannot hear) preventing
you from transmitting while other groups are using a channel.
If the channel is busy when you try to transmit, a series of low-pitched tones
sound until you release the PTT.
Scan
Your radio is equipped with scan, which allows you to search for activity on
multiple channels. When activity is found on a channel, the radio locks on
and suspends scanning. Scan will always search for and go directly to a priority channel, even if scan has locked onto another channel.
1
Press to activate the Scan Mode.
The channel LEDs light in the order the channels are scanned.
When activity is found during scan, the active channels’ LED lights.
