possible with some frequency bands only – see the frequency band
chart).
K. LOCK: microphone (UP/DOWN buttons) lock enabled.
4. “ON/OFF Volume” Control: in ‘’off’’ position your transceiver is OFF. Turn
this control clockwise to switch on the unit. Turn the knob clockwise a
little more to set the audio level, until you get a comfortable reception.
With ‘’PA-CB’’ selector set in ‘’PA’’ position, the knob controls the audio
output level.
5. “Squelch” Control: for the maximum receiver sensitivity, the control
must be regulated exactly where the receiver background noise disap-
pears.
6. “RF” (Radio Frequency) Gain Control: it controls the reception sensitivi-
ty. To increase sensitivity, simply turn it clockwise. Sensitivity decreases
turning it counterclockwise. Low sensitivity is useful when very strong
signals are present in the band.
7. “Mic (Microphone) Gain Control”: in TX mode, it controls the micropho-
ne amplification. To get the best results, use the microphone and set the
optimum position for both the distance from your mouth and for the
amplification level, asking your partner when the modulation comes out
better.
8. “M1-M2-M3-M4” buttons: These buttons allow the storing and recalling
of 4 preselected channels. How to store: select the desired channel and
press M1 for at least 3 sec to store the choosen channel in the M1 memo-
ry. Repeat these steps to memorise the other presets.
9. EMG button: Emergency channel. By pressing it, the unit will be auto-
matically positioned on CH 9 (emergency channel). The display will show
“EMG”. It will not be possibile to accidentally change the channel.
