Common Troubleshooting Procedures
Follow these procedures to resolve common issues.
Resetting Devices
You may need to manually restart a device or return a device to factory defaults (see
“Appendix D: Default Settings” on page 121). To reset a device, press the RESET button
shown in Figure 26 and Figure 27 on page 98 by inserting a pen or paper clip into the
hole and applying pressure to the button.
If the device does not respond or fails to synchronize with the system, the device should
be restarted. To restart the device without losing any custom settings, press the RESET
button for less than five seconds. You can get the same result by disconnecting and
reconnecting power to the device.
To completely reset the device to factory defaults, unplug the LAN cable and press the
RESET button for more than five seconds. You might do this if the device is not
synchronized or you want to reset the IP address settings to Auto (DHCP). Any static IP
configurations are lost.
When resetting a Deskset to factory defaults, the User Settings, Personal directory, voice
messages, Call Log, and the Redial list are all deleted. You can use this complete reset
when assigning Desksets to new users. If you do not disconnect the LAN cable before
pressing the RESET button, the extension number is retained. During the reset, any PC
connected to the Deskset PC port momentarily loses network connectivity.
If there is one Gateway in the system, but there are still Desksets connected, then only
the voice prompts and hold messages are deleted; the rest of the Auto Attendant settings
are maintained on the Desksets. If there is another Gateway, the other Gateway
maintains all system configuration settings.

To reset the entire system to factory defaults and completely clear the system
of all settings (Auto Attendant, hold message, and System Directory) and voice
messages, unplug the LAN cables from all devices and press the RESET button
for more than five seconds on each device. Then reconnect all devices to the
LAN.
If you have already set up the system, back up the Deskset and system settings
before resetting the device to factory defaults. See “Back Up and Restore
Settings” on page 70.
