External DTMF remote 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 tone squelch function can be used for the sub band to
increase remote control reliability. (p. 86)
w Program a 3-digit password into the sub band’s code
channel 5
(“PGR MEMORY”), if desired. (p. 94)
• The initial value of code channel 5 is “000 (default); receive
accept.” If you do not require the password, set the channel as
“receive inhibit.”
e Select the main band by pushing the desired band’s (Left or
Right) [MAIN•BAND], then set the desired frequency for
operation.
r Push and hold [TONE•DTMF] for 1 sec. to enter DTMF set
mode, then rotate [DIAL] to select “REMOTE CONTROL.”
t Push [MAIN•BAND], then rotate [DIAL] to select ON.
y Push [BACK](V/MHz•SCAN)
(Right band’s) twice to return
to frequency indication.
•
“
R” indicator appears
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 tone squelch
function with the IC-2820H.
• The external DTMF remote does not accept a control signal on
the main band frequency.
i From the controller transceiver, transmit the DTMF code
as follows:
o To cancel standby for the remote control, select “OFF” in
“REMOTE CONTROL” item in DTMF set mode.
• “R” disappears.
