Dual Tone Multi Frequency (DTMF)
The Dual Tone Multi Frequency (DTMF) feature allows the radio
to operate in a radio system with an interface to telephone
systems.
To use this feature, your radio must have an access code, which
is system dependent. Please check with your dealer or system
administrator for more information.
Procedure:
To initiate a DTMF call.
1 Enter the Access code.
2 Press and hold the PTT button.
3 Enter the desired number.
NOTE: You can turn off the DTMF tone by disabling all radio
tones and alerts (see Turning the Radio Tones/
Alerts On or Off on page 56).
Security
You can enable or disable any radio in the system. For example,
you might want to disable a stolen radio, to prevent the thief
from using it, and enable that radio, when it is recovered.
NOTE: Performing Radio Disable and Enable is limited to
radios with these functions enabled.
