Autopatch
Operations
(U.S.A.
versions
only)
Some repeaters offer a service known as autopatch. This
feature allows you to dial a telephone
number
from
your transceiver and carry out a telephone conversion,
much
like a car telephone,
or cellular telephone.
This
function requires the use of a DTMF (Dual Tone Multi
Frequency)
pad.
The MC-44DM
microphone
provides
the normal keys you would have on your telephone at
home, as well as 4 additional
keys. the A,B,C, and
D
keys. These keys are used for control operator of the re-
peater to see if they offer autopatch services.
To activate the keypad:
1. Press and hold the PTT key.
2. Press the keys just like you would dial your telephone
at home.
3. The transceiver will remain keyed for approximately
2 seconds after you press each number, so you can re-
lease the PTT switch without unkeying the transceiv-
er.
Note:
Some repeaters will require the use of a special key
sequence
to activate the Autopatch
function.
You
should
check
with
your
control
operator
for this
sequence.

TONE /CTCSS OPERATION
With the use of the optional Sub-Audible tone decoder
unit (TSU-6) you will be able to operate in a Tone Oper-
ated Squelch Mode. When this option is installed and
the CTCSS function has been activated the radio will not
open squelch until the proper PL tone is received.
Press the TONE/T.ALT key and select the desired Tone
mode.
When the T indicator appears in the display the
transmitter will transmit the desired tone.
When
the
CTCSS indicator appears in the display the transceiver
will transmit the desired tone and will also operate in
the Tone Squelch mode. i.e. squelch will not open until
the same tone is received as a portion of the incoming
receive signal.
When
no indicator is on the radio will
not make use of either tone feature.

Note:
Even if the TSU-6 is not installed, tone signals can be
transmitted,
so the tone squelch of the other trans-
ceiver can be opened.
