GP1200 user instructions.
1). Turn the radio on, using the left-hand knob.
After switch on the radio will bleep and then display a" z
" symbol. This will turn in to a " 0 ( with a diagonal
line) ", which indicate the unit has logged on to the
system. If the radio does not display " 0 " it cannot
make or receive calls.
2). To answer a call, press the PTT after you are
called. The radio displays the callers ID in the display. You
have 10 seconds to answer a call, and during a call, if neither
party speaks for 6 seconds the call will be terminated.
3). To make a call to the group, depress the small
button above the PTT. This makes a fixed call to your group. The
radio display shows "calling" and then either a
decrementing timer if the call is successful, or
"queued". if the call is successful use the PTT and the
radio as normal. If the display shows "queued" then do
no more, this means that the system is busy. You will be
automatically routed to the group when the call in progress
finished without any further action on your part. The radio
alerts you with a bleep when you can talk. The system operates a
proper queue system so that there is no need to retry.
4). To call other units, rotate the top selector so
that other pre programmed groups etc appear in the display, when
they are shown repeat the process above. NOTE this process does
not put your radio in this group, but merely lets you make calls
to this group. You will NOT now hear calls meant for this group.
5). If you are calling an individual radio in this
manner, "queued" may again appear. In this mode it does
not always mean that the system is busy, it can indicate that the
party that you are calling is talking to someone else.
6). If you get "unavailable" it means that
the party you wish to call is out of range or has his radio
turned off.
7). If your radio is enabled to call individual
radios, you can do this by entering their number on the keypad,
and then pressing the PTT or the # button.
8). To terminate a call press the green button above
the PTT. If you have made a group call this will terminate the
call to ALL the group radios, however if you have received a
group call this terminates the call to your radio only ( and
hence may be used to stop you hearing messages meant for others )
and not the rest of the group.
9). Pressing and holding the orange button on top of
the radio ( for two seconds ) will make a fixed emergency call to
the base.
10).Various other facilities are available ( if
programmed for your radio )as follows :-
Broadcast call.
Enter *11* and then a group number (such as 990) This
sends a Broadcast call, which all radios can hear, but cannot
respond to.
Priority call.
Enter *8*and then the radio ID that you wish to talk
to. This lets you jump the queue if a number of other people are
calling this unit and you get a queued message.
Emergency call.
Enter *9*and then the radio ID that you wish to talk
to. This lets you terminate calls to the radio ID that are
currently in progress. If a number of other people are calling
this unit and you get a queued message. Please use the last 2
functions sparingly, as they are there for real emergencies.
Indiscriminate use can cause mayhem!
To put a radio into Conventional mode ( i.e. back to
back walkie talkie ) then after power up, and when the
"z" appears in the display, press and hold the middle
button above the PTT, when "conventional" appears in
the display you have a normal radio. To return this radio to
trunk mode, reverse the process, releasing the button when
"personality 1" appears in the display.
