Battery Backup (Memory)

The DX-80 system is equipped with a Lithium Ion battery for maintaining volatile system database programming and
extension programming during commercial AC power interruption. The memory backup will maintain the database
programming, time and date displays, personal speed dial numbers, feature button programming, etc., for up to
seven (120) days of continuous AC power loss. When system AC power is restored, the system will resume normal
operation.
During AC power interruption, the system will not operate unless System Battery Back-Up via a UPS is equipped.
When the "Cold Start/Normal" option strap on the CPM Module is operated to the "Cold Start" position, with the KSU
AC power turned off, the memory backup battery is removed from the volatile memory circuit. This option strap
condition is used only to initialize the system database and restore all programmable data to the factory configured
default program.
