appears on the display and the menu (right/left) and Up/Down buttons are
disabled.
2. To exit from the key lock mode, press and hold the Function (F) button until the
key lock icon disappears from the display.
BASIC RADIO OPERATION

2. Press and hold the PTT (Push-to-Talk) button while speaking slowly and clearly
in a normal voice, approximately 2 to 3 inches from the microphone.
3. The transmit indicator (T) will be displayed while transmitting.
4. Release the PTT (Push-to-Talk) button when you finish speaking to receive
incoming signals.
TO RECEIVE:
1. Set the desired channel and CTCSS code.
2. Adjust the volume control to the desired listening volume by using the up
and down buttons.
3. The transceiver will play strong received signals through its internal speaker
or through a headset, if so equipped, and the Receive Signal Strength Indicator
(
), together with the appropriate level indicator (0-9) below, will display the

MONITOR FUNCTION
The Monitor (M) button can be used to play all signals present on a channel. This is
useful when communicating with other parties at extreme range. The monitor function
can also be locked on by pressing the Monitor (M) button for 3 seconds; a two-tone
melody will sound. When the monitor lock has been activated, the radio will issue
background noise until a voice transmission is received. Momentarily pressing the
monitor button again will unlock the monitor function.
