I Programming a DTMF code

DTMF codes are used for autopatching, accessing repeaters,
controlling other equipment, etc. The transceiver has 10
DTMF memory channels (D0–D9) for storage of often-used
DTMF codes of up to 16 digits.
q Push [• DTMF.M] for 1 sec. to enter DTMF memory.
w Rotate [DIAL] to select the desired DTMF memory chan-
nel.
• "T-CALL" appears when a 1750 Hz tone burst signal is selected.
(p. 34)
e Push [• DTMF.M] for 1 sec. to enter programming mode.
• Previously programmed DTMF code is cleared.

r Push the desired keys to input the characters.
• [VFO] inputs "A," [MR] inputs "B," [CALL/TV] inputs "C," [BAND]
inputs "D," [•] inputs "M" (E) and [MODE] inputs "F" (#).
• Up to 16 digits can be programmed.
t Repeat r until the desired code is input.
The display returns to 1st display
when 16th digit is input.
y Push [SQL] or [PTT] to program the DTMF code and exit
programming mode.
• Entering 16th digit automatically exits the programming mode.
Next display appears when
7th digit is input.
