Switching the radio ON/OFF
To switch the radio on:
1) Hold the
(power) button until the radio is switched on: the LCD
will start an autotest showing in sequence:
• A welcome message (if previously programmed – it is usually
your company name or your personal station identification). At
the same time all the LCD icons will be shown for one second
as LCD test.
• The firmware release number
(
FW Rev.)
.
2) After the autotest has been carried out the LCD will steadily show
the following data:
• The battery level with
. As many bars you will see, as greater
is the residual battery duty.
• The channel name/number on the first line (a specific twelve
alphanumeric characters identification name), it could be the
last recalled channel or a previously programmed specific one.
• The current volume level with an LCD bar indication. As more
bars you will see as greater is the volume setting.
• The currently selected TX output power:
L
(low) or
H
(high) in the
lower right corner of the LCD.
To switch the radio off just hold the
key pressed until the transceiver
will switch off.
Reception
Your radio could be previously programmed to work, channel by
channel, in “Open traffic”, “CTCSS/DCS” or “Selcall” mode. Please
have a look to each description and ask your radio network manager
or dealer which mode your radio channels work.
•
OPEN TRAFFIC: in this case you will hear any communication
which will be transmitted on the selected channel. When any signal
is received your squelch will unmute and you will see in the LCD
the icon
(speaker enabled), (squelch is open),
(reception
field strength level – the number of bars will vary according to
the received RX strength). Moreover you will see the status LED
glowing green and you will hear the message.
•
CTCSS/DCS (Continuous Tone Code Squelch System - Digital
Coded Squelch): they are systems which use particular TX signalling
(a continuous sub audio tone for CTCSS or a digital code for DCS)
as an access “key” to work a repeater (encoder) or to unlock the
party’s signalling sensitive squelch. This last condition allows to
share more radio networks in the same frequency. In this case
you will receive only messages coming from parties sending a
proper TX signalling. Please see the chapter “Selcall Operation”
for further details.
•
SELCALL (Selective call): it’s a system which uses a signalling
sequence (e.g. audio tones for “5 tones” and DTMF selcall or a
frequency shift signalling for FFSK) to call a particular station or
group(s). In this case you will receive only calls provided with your
identification selective call code (a number) or calls sent to the
group you own. For further details please see the chapter “Selcall
operation”.
