The following service modes are provided to assist you in setting operational functions of the unit and
determining the condition of the unit.

The factory default parameters are preset (destination dependent) for optimum performance and in 
compliance with the local telecommunication regulations/standards, and do not need to be changed. 
Changing some of these parameters may cause the unit to be no longer compliant or become 
inoperable.
