EXTERNAL DTMF REMOTE
External DTMF remore function can be remotely controlled
using DTMF signals on the sub band. To operate external
DTMF remote, a 144MHz or 430(440) MHz transceiver with a
DTMF encoder is required.
q 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. Tone squelch)
w Enter "DUP/TONE"
e Program a 3-digit password into "PGR CODE" the sub
band's code channel 5, if desired.(p. ??)
• The initial value of code channel 5 is "000 (default); receive ac-
cept." If you do not require the password, set the channel as "re-
ceive inhibit."
r Select the main band by pushing a tuning dial, then set the
desired frequency for operation.
t Push and hold [TONE•DTMF], then rotate [DIAL] to select

u Set the operating frequency of the controller transceiver
equal to the sub band frequency of the IC-2820H.
• Make sure a tone frequency is set when using the optional tone
squelch function with the IC-2820H.
• The external DTMF remote does not accept a control signal on
the main band frequency.
