Install/Replace Backup Battery
The ZN90 uses a backup battery system to provide continuous alarm operation and clock settings in the event
of a power failure. If the Battery Low Icon located on the right of the display is flashing, it is time to replace the
backup batteries. Please make sure the AC adaptor is connected, otherwise all settings may be lost during
battery replacement.
Open the battery compartment cover located on the bottom of the unit. Insert 2 “AA” batteries as indicated.
We recommend the use of alkaline batteries for longer life.
