One Touch Private Call
The MTM800 supports the one-touch private call if it is set by the
Service Provider. User can dial the last group call originator number
via pressing the assigned one touch private call button.
The required time you need to press the Numeric keys to activate a
one-touch function is set as default to 1 second. This time may be
set, however, by your service provider.
For information on the function assigned to each F1 to F3 or
Numeric keys please refer to your Service Provider.
