EXTERNAL DTMF REMOTE (U.S.A. version only)

When installing the optional UT-49
DTMF DECODER UNIT
, the
U.S.A. version can be remotely controlled using DTMF sig-
nals on the sub band. To operate external DTMF remote, a
144 MHz or 430(440) MHz transceiver with a DTMF encoder
is required.
➀ Set the sub band frequency to receive a control signal
(DTMF code).
• The optional tone squelch function can be used for the sub band
to increase remote control reliability. (p. 54)
➁ Program a 3-digit password into the sub band’s code chan-
nel 5, if desired. (p. 58)
• The initial value of code channel 5 is “000; receive accept.” If you
do not require the password, set the channel as “receive inhibit.”
➂ Select the main band by pushing a tuning dial, then set the
desired frequency for operation.
➃ Push [DTMF] one or more times until “REMO” appears to
select standby for the remote control.
➄ Set the operating frequency of the controller transceiver
equal to the sub band frequency of the IC-2710H.
• Make sure a tone frequency is set when using the optional tone
squelch function with the IC-2710H.
• The external DTMF remote does not accept a control signal on
the main band frequency.
➅ From the controller transceiver, transmit the DTMF code as
follows:
•“#” and “REMO” flash while receiving a control signal.
➆ To cancel standby for the remote control, push [DTMF].
•“REMO” disappears.
• Pushing [FUNC] then [FD-OFF] also cancels standby for the re-
mote control
