Operation
Before operating the PRO 340XL:
1. Be sure you read and understand Part 95 of the FCC Rules
and Regulations.
2. Be sure that the batteries and antenna are properly installed.
3. Turn the unit on by sliding the power switch up to the
ON position.
Receive
1. Use the Up/Down channel keys to select any of the 40
channels. Press once to change one channel at a time.
Press and hold to rapidly change channels.
2. Set the
VOLUME
control to a comfortable listening level.
3. Adjust the
SQUELCH
control to eliminate background
noise during the absence of a signal. Move
SQUELCH
to the right until the noise disappears (no signal should be
present). Leave the control at this setting. The receiver will
remain quiet until a signal is actually received.
NOTE: Do not advance the control too far, or some weaker
signals will not be heard.
4. Set the TONE/HIGH switch to TONE if the received
transmission has too much noise. This reduces the
high tones.
Transmit
If the channel is clear, press the
Push-To-Talk Button
on the
side of the unit. The TX indicator lights red. Be sure to speak
clearly into the microphone.
IMPORTANT:
All channels, except channel 9, may be
used for normal communication. Channel 9 is reserved
by the FCC for emergency communications involving the
immediate safety of individuals or the protection of
property. Channel 9 may also be used to render
assistance to a motorist.
This is an FCC rule and
applies to all operators of CB radios.
