Responding to Alarms
This section describes response to battery, sensor, clock, system, and
microprocessor failure alarms.
Responding to Battery Alarms
WARNING: The Gas Tracer is not operational as a gas monitoring
device during a dead battery alarm. Take the Gas Tracer
to a non-hazardous area and replace or recharge the
batteries as described in “Replacing or Recharging the
Batteries” on page 85.
The Gas Tracer is fully functional during a low battery warning.
However, only a limited amount of operating time remains,
approximately 1 - 2 hours. The amount of time depends on how often
the LCD backlight is used and how often the unit is responding to
alarm conditions. Recharge the battery pack or replace the alkaline
batteries as soon as possible as described in “Replacing or Recharging
the Batteries” on page 85.
