Restarting, Updating Firmware, Factory Reset

If your phone is malfunctioning or require updates you or your phone system administrator may want to perform one of the following:


Restarting - this will bring the phone back to the its last configured state. It is also required sometimes when TeleConsole settings have been updated such as after modifying TeleConsole BLF settings.


Updating firmware - firmware is the software that loads when the phone is started and controls its functionality. Updating it to a newer version when one is released may resolve or improve phone performance issues. 


Factory reset - this erases the current configuration and apply the original configuration the phone was shipped with from the factory. You can reset the the base station or each individual handset.

In most cases this can be attempted when your phone malfunctions without much concern. If this fails to solve the problem you can attempt the other two methods.
