SENDING A MESSAGE
1. Turn the radio on and set the desired System and Channel as described
in the previous section.
2. Ensure no one is transmitting on the selected channel by pressing the
SHIFT/CLR button twice ("double click") and/or observing the display
for the absence of the "BSY" indicator to ensure that no one is
transmitting on the selected Channel.
3. Holding the radio about 3 inches from your mouth, press the PTT bar
and speak as you would normally into the microphone.
4. Release the PTT bar when the transmission is complete and listen for
any reply.
SQUELCH ADJUSTMENT
In normal operation the squelch is automatically set by the radio and
does not need adjusting. If it becomes necessary to adjust the squelch, the
squelch may be adjusted using the following procedure:
1. Press and hold the SHFT/CLR button.
2. Use the VOLUME s or t buttons to adjust the squelch. Pressing the
VOLUME s will open the squelch and pressing the VOLUME t will
close the squelch.
SENDING A MANUALLY ENTERED INTERCONNECT CALL
1. Select a channel in your radio system that has telephone interconnect
capability. The radio should be programmed for DTMF operation on
this channel.
The radio must be on a Conventional System or an EDACS working
Channel (i.e. receiving a voice call) to adjust the squelch. It is
recommended to adjust squelch from a Conventional System.
