3-6-4 AUTOPATCH
(TH-25AT/45AT/55AT U.S.A. version only)
jfeo'me repeaters offer a service known as autopatch. This
allows you to dial a telephone number from your
transceiver and carry out a telephone conversation, much
like a car telephone, or cellular telephone. This function re
quires the use of a DTMF (Dual Tone Multi Frequency) pad.
In addition to the normal 12 keys that are found on your
telephone the transceiver also provides 4 additional keys,
A, B, C, and D. These keys are required by some repeater
systems for various control functions. You should check
with the control operator of your repeater to determine if
their use is required. A chart is provided that lists the tones
that are generated when you press each key.
1. To activate the DTMF pad, press and hold the PTT
switch.
2. Now press the keys just as you would dial a telephone.
Note:--------------------------------------
Some repeaters will require a
special sequence of keys to ac
tivate the Autopatch. Again
you should check with the con
trol operator of your repeater
for this sequence.
