Emergency Alkaline Battery Adapter
The alkaline battery adapter supplied by RAE Systems is intrinsically
safe.
The adapter is intended to be used in emergency situations
when there is no time to recharge the Li-Ion battery pack. The adapter
accepts 4-AA alkaline batteries to provide approximately 12-14 hours of
operation.
To install
the adapter, remove the monitor cover. Remove the Li-Ion
battery pack from the monitor by carefully disconnecting the wires.
Install four AA alkaline batteries into the battery adapter, making sure
the battery polarity is correct.
Connect the battery adapter to the monitor. Make sure the wires are
placed inside the adapter, running between the batteries. Close the flap
over.
Install the battery adapter in the monitor.
!
The monitor automatically detects the alkaline batteries and will run
for 8-10 hours. Use the monitor once the alkaline battery adapter is
installed. Replace the alkaline batteries when spent.
