4et the Channel Selector to a channel where no signals are present or
wait until signals cease on your channel. Then, rotate the Squelch
control in a clockwise direction to the point where the background noise
just stops. Now, when a signal is present, you will hear it, but will not be
disturbed by noise on the channel between signals. When properly set,
the Squelch keeps the receiver “dead” until a signal comes in on that
channel. However, do not set the Squelch too high, or weak signals will
not be able to open the Squelch circuit. To receive very weak signals, it is
best to leave Squelch set to the minimum position by rotating the
control maximum counterclockwise. The Squelch circuit in your
transceiver is an advanced design. It uses an operational ampMJGJFS IC to
accomplish a hysteresis action. The result is that when you set the
Squelch for a precise signal level, if that signal level increases or
decreases in strength, the Squelch circuit will follow this change. With
conventional Squelch circuitT, often a signal which changes strength get
“chopped” by the Squelch circuit and aportion of the messageJTMPTU.

Press the push-to talk button on the microphone and hold about
5-7 cm from your mouth and speak in a normal voice.
To receive, release the push-to-talk button. Be sure the mic plug is
firmly connected to the jack.
NOTE: shouting into the mic will not increase your power or signal.
An internal circuit automatically sets the mic signal for
maximum modulation, so speakJOH loudly will give no advantage.
SELECTION OFBANDS
Turn on the radio while keeping pressed the UP/DOWN controls
With the UP / DOWN buttons select the desired band:
"V = "VTUSBMJB(40 C) AM - 26.9627.40)
