X16 Memory Backup & Surge Protection
The X16 system's program memory is protected during power outages. However, the phones will lose voice mail related programming, recorded messages and greetings if they are unplugged from the system for more than 2.5 minutes. Use of an external battery back up system or uninterrupted power system (UPS) can prevent loss of programming, recordings and greetings.
Use of a UPS is also beneficial because these types of back up systems typically reduce power fluctuation and surges that can damage the X16 system. Stand-alone or UPS-based AC power surge protectors are recommended to reduce AC power-related damage.
In addition, telephone system CO line ports can be damaged by power surges related to thunderstorm activity and nearby lightning strikes. Therefore, use of CO line surge protectors are recommended in addition to use of AC power surge protectors.
