Step Seven
• Only rotate SQUELCH until the hissing stops. If you continue to
rotate it clockwise, you will be unable to receive any signals.
• You maywant topurchasean SWR(StandardWaveRatio) meter
to measure your range and signal strength. This will enable you
to adjust your antenna for maximum range, and determine the
best position for RF GAIN. See your SWR meter owner’s manual
for instruction on how to use it.
• You cannot transmit when CB/WX is set to WX.
• Because ofatmospheric conditions, you may receive signalsthat
do not contain information relevant to the emergency level. This
is normal.
• The radio sounds an alert regardless of the channel setting.
• The CB will not sound an alert while you are transmitting.
• If you are in a rural or fringe area, your radio might be triggered
by an alert broadcast in one area, but not be triggered if you
travel to another area (even close by).
• Most 12-volt DC power supplies plug into a standard AC outlet to
produce DC power. Before connecting your CB to a 12-volt DC
power supply, read and follow the instructions included with the
power supply.
