memory different from 1.
To recall a channel previously stored, push the "FUNC" switch and the
button of the desired memory.
These buttons have two functions; herebelow you will find their
descriptions:
"M1 - EMG" switch
9.
This switch allows the storing of the first memory and the recalling of the
2 emergency channels. "M1 - EMG" selects sequentially channels 9 / 19
(emergency) and the one in use.
10. "M2 - DW" button
"M2 - DW" stores the chosen channel in the M2 memory and activates the
DUAL WATCH. This function allows the synthonization on two different
channels at the same time:
when a signal on the second channel is received, the conversation on
the first one is automatically interrupted and the receiver switches on the
second channel. The monitoring starts again 5 seconds after the signal end.
To activate this function, operate as follows:
- Select the desired channel through the channel selector or the "UP/
DOWN" buttons on the microphone;
- Keep the "DW" button pressed for about 3 seconds: you will hear a "BIP"
and "DW" will flash on the display.
- Select the second channel with the same procedure;
- Press the button "DW" again for roughly 3 seconds: you will hear ano-
ther "BIP"; the display will permanently show "DW" and will alternati-
vely visualize the two selected channels.
11. "M3 - SCAN" switch
The two functions of this button are: memorization of the third channel
in the M3 memory and "SCAN" function activation. In this case, you can
automatically seek for a busy channel:
• turn the squelch clockwise until the background noise is no longer
heard;
• press the "M3 - SCAN" button: "SCAN" will be shown on the display and
the transceiver will automatically scan all the channels until a carrier is
being received.
This function can be deactivated in three ways: pressing the PTT but-
ton, turning the channel selector or simply pushing any other button
on the unit.
12. "M4/LCR - AM/FM" button
Stores the memory number 4 and selects the operative mode (AM/FM).
AM: green LED; FM: red LED. If you select a frequency band operating in
FM modulation only, this button activates the LCR function (Last Channel
Recall).
13. "M5 - LOCK" switch
Pressing this button, you memorize the fifth (last) memory and activate the
"LOCK" function (it allows the locking of the keyboard, channel selector and
"UP/DN" buttons on the microphone, thus avoiding accidental use of the
keys).
14. N.K. button
Pressing this switch, you activate the reducing noise device (see introduc-
tion).
15. "MIC" knob
The amplification of the voice in TX must be adjusted with this knob. The
optimum level of the modulation must be found with the help of your
receiving partner.
16. "RF" knob
It controls the reception sensitivity.
To increase sensitivity, simply turn it clockwise. Sensitivity decreases turn-
ing it counterclockwise.
17. "VOL" knob
It allows the switching on of the unit and sets the volume to a comfortable
audio level.
18. "Squelch" knob
For the maximum receiver sensitivity, the control must be regulated exactly
where the receiver background noise disappears.
