Reloading Factory Defaults
Desk sets are shipped from the factory with default settings that meet most installation requirements.
However, it is important to verify that these parameters are adjusted to meet your specific installation
needs.
To reload factory defaults, enter the Main Diagnostic Selection as described below. After entering this
mode, press
CTL + VOLUME Up. The unit will automatically reset and show that the parameters are
corrupt. Follow the instructions on the display. For some models, this may happen twice.
N OTE : If your unit has been programmed with CARD Suite software, reloading the factory defaults will
reset all parameters that have been programmed.
