Dtmf (Dual Tone Multiple Frequency); Page Mode - GME TX3600 Series Instruction Manual

(DUAL TONE MULTIPLE
FREqUENCY)
DTMF signaling can be used for dialling telephone numbers
or activating devices by remote control. If DTMF is available
on your radio, the method you will use to send DTMF signals
will depend on the options programmed.
Using the DTMF Speed Dial memories
DTMF Speed Dial memories are used when your radio
has been preprogrammed with the necessary DTMF tone
sequences for your application, with no provision to
manually alter them.
DTMF Speed Dial memories may be programmed into one
or more of the function keys (F1, F2, F3, F4).
To send a DTMF signal using a Speed Dial memory, press
and hold the appropriate function key (F1, F2, F3, F4) until
a high beep is heard. The 'TX' indicator will appear on the
display as the DTMF tone sequence is sent.
Using the DTMF Speed Dial memories with
Channel Recall
your DTMF Speed Dial memories may also have been
programmed to automatically go to a specific channel before
sending your DTMF signal.
To send a DTMF signal using a Speed Dial memory
programmed with Channel Recall, press and hold the
appropriate function key (F1, F2, F3, F4) until a high beep
is heard. The radio will change to the preprogrammed
channel and the 'TX' indicator will appear on the display
as the DTMF signal is sent. The radio will then stay on the
preprogrammed channel.

Alarm Input
The 'alarm input' is an interface on the TX3600 Series which
can be used to monitor an external contact closure and send
a pre-programmed selcall on a designated channel when the
input becomes active. In this case, the radio will commence
an Alarm Cycle:
1. hold the radio supply voltage 'oN' (if not already on)
2. Show 'ALArM' on the display
3. Jump to the designated 'Page' channel
4. Transmit a pre-programmed selcall ID a specified number
of times. If 'append ANI' is selected, the radio's own ID
will be appended to this selcall.
If the radio power was ON when the alarm input was
triggered, the radio will return to the previous operating

channel but the 'ALArM' state remains latched, i.e. no
further alarm cycles can be initiated.
To clear the ALARM state, simply press any key on the
radio or the microphone.
If the radio power was OFF when the alarm was triggered,
the radio will complete the Alarm Cycle and turn itself OFF
at the end. In this case, the alarm input can trigger a new
Alarm Cycle at a later time.
Alarm Output
The alarm output port is an open collector output capable
of driving an external signalling device - typically a horn, or
a flashing light. If enabled, the alarm output will become
active when the radio receives an individual or a group
selcall, or if the special *ALrM selcall ID string is matched
during a selcall lookup.
The exact alarm output sequence, i.e. the number and
duration of relay closures, is fully programmable.

PAGE MODE

If enabled by your retailer, the PAGE or transpond feature
allows you to leave your radio unattended yet still be informed
of any incoming Selcalls. If your Selcall Ident is received while
your TX3600 Series is in the PAGE mode, it will automatically
call another UHF radio to alert you to the call.
Note: To allow your TX3600 Series to operate in the PAGE
mode when your vehicle is unattended, your radio must be
wired so that it has a continuous 13.8 Volt power source.
Selecting the Paging Channel
your TX3600 Series Paging channel is pre-programed by
your retailer.
Setting the Paging Ident
The PAGE Ident is the Ident of the receiver you will use to
receive the paging call. Depending on your requirements,
the Paging Ident may be fixed by your retailer, or provision
may have been given for you to program it yourself. It is
programmed in the same way as Selcall Idents and is stored
in Selcall memory 39.
To program the Paging Ident:
1. Briefly press the CaLL key on the microphone. 'Call To' will
appear on the display, and the Selcall Ident for memory
location 1 will be displayed. If the radio is in Alpha mode,
the Ident may display a label representing the Ident instead
of the Ident number itself. If there is no label programmed,
the selcall display area will be blank when in Alpha mode.
2. Rotate the Channel Selector knob to select Selcall
memory 39. The selected selcall memory number is
displayed in the channel display area. If Alpha mode is
