3.11 Talkaround (GP340/GP360/GP380 only)
Feature
Talkaround allows a system to be bypassed. A system is used to cover a larger communication area
than is possible with just a radio alone. Once the system is bypassed, it will only be possible to
contact other radios which are within the normal communication range.
Benefit

Continued communication even when parts of the system are taken out of service for
maintenance.
3.12 DTMF
Feature
DTMF (Dual Tone Multi Frequency) is used when the radio is required to operate with an interface to
a telephone system.
On all radios a DTMF encode sequence can be sent, and
on the GP380, the keypad can be put into DTMF live dial mode.
3.12.1 DTMF encode sequence
All radios can send pre programmed DTMF sequences. Each DTMF sequence can contain up to 24
DTMF digits. The sequences cannot contain a combination of 5T and DFMF digits; however, 5T and
DTMF sequences can be combined in a telegram.
Benefits

Link up with a telephone network to extend the communication system.

Pre programmed DTMF sequences allow all radio users to call frequently needed telephone
numbers (max 32 sequences).
3.12.2 DTMF Live Dial Mode (GP380 only)
There are two ways to access DTMF live dial on the radio:
1. Send a telephone interconnect call (5T or DTMF sequence) to a station that connects to a
telephone line. The radio can then send DTMF live dial calls from the keypad. On completion
of the call, the radio (if programmed) sends a cleardown call (5T or DTMF sequence) and the
keypad returns to the default keypad mode.
2. Press a button pre-programmed to enter DTMF mode. The radio then sends DTMF live dial
from the keypad. If needed, DTMF interconnect and cleardown calls can be sent from call
buttons or live dial entry on the keypad. The radio keypad remains in DTMF live dial mode
until the DTMF mode button is pressed again. When the radio exits DTMF mode, the keypad
returns to the default keypad mode.
Benefits

Link up with a telephone network to extend the communication system.

Live dial allows the user to dial any DTMF telephone number.
