Audible Alarm Battery Backup
The alarm system is protected by a battery backup system in the case of power and/or
system failure. The battery is designed to operate the audible alarm and data recording
system for up to 24 hours. When a power failure occurs, with the battery switched on,
the power failure audible alarm sounds immediately and the main display shuts off to
conserve power.
You can activate the LCD screen by pressing any directional key. When you do, the
internal temperature will be displayed on the screen, which will remain on briefly, then
shut down again to conserve power. Be sure to take note of the following cautions:
CAUTION!
Frequent operation of the display during a power failure will
substantially reduce the life of the alarm battery.
CAUTION!
Opening the freezer door during a power failure will increase the cabinet
temperature.
CAUTION!
Failure to turn on the alarm battery switch will disable the audible alarm
system and data recording during a power failure.
The alarm battery backup system does not affect the external alarm monitoring socket.
The alarm socket is designed to operate regardless of the condition or state of the freezer
or alarm battery.
