control. A common example would be in amateur
radio repeaters where some repeaters are activat-
ed by sending out a DTMF sequence (usually a
simple single-digit sequence).
DTMF frequencies and corresponding codes
1209Hz 1336Hz 1477Hz 1633Hz
697Hz 1 2 3 A - [MENU]
770Hz 4 5 6 B - [UP Y ]
852Hz 7 8 9 C - [DOWN Z ]

The product has a full implementation of DTMF,
including the A, B, C and D codes. The numerical
keys, as well as the [
✱
/SCAN] and [#/LOCK] ,
keys correspond to the matching DTMF codes as
you would expect. The A, B, C and D codes are
located in the
[MENU] , [UP Y ] , [DOWN Z ] and
[EXIT/AB] keys respectively (+).
Manually TX DTMF Tones: To manually send
DTMF codes, press the key(s) while holding down
the PTT key.
Automatically TX DTMF Tones: Save it to Mem-
ory and Transmit: You can also program a DTMF
tone to the saved calling list (requires the PC
software) to the one of the 15 Memory call banks
in the radio. To transmit select the Pre-set DTMF
saved setting on Menu 22 and then press the call
key to send the saved DTMF TX tone.

First set the DTMF Remote Stun Tone and
Master Control ID in Software:
When your radio
receives the DTMF Remote Stun Tone Sequence
(Set by software) (Requires Menu 18 and 19 to
accept DTMF signaling) it will command the ra-
dio to disable transmitting abilities. The Master
ID station must first identify and send the PTTID
(set in software as “Master ID”) – once the Master
Station identifies itself, the radio is set to receive
command tones, if the Monitor Remote Stun tone
is received - the radio will no longer be able to
transmit. Both the master ID station and remote
stun signal must be set up in software.

Remote Kill
First set the DTMF Remote Kill Tone and Mas-
