If Replace battery is displayed, the battery is unreliable, regardless of the operating time displayed under Batteries. In this situation, replace the battery even when the STATUS window indicates that significant operating time remains. When using an external 12V DC supply, two battery modules must be installed to ensure proper operation. The No battery capacity alarm and high priority technical alarms cannot be silenced.
WARNINGS!
