WARNING!
To reduce the risk of ignition of hazardous atmospheres, recharge
and replace batteries only in areas known to be non-hazardous
.
Remove and replace batteries only in areas known to be non-
hazardous.
Low Voltage Warning
When the battery’s charge falls below a preset voltage, the
instrument warns you by beeping once and flashing once every
minute, and the “empty battery” icon blinks on and off once
per second. You should turn off the instrument within 10
minutes and either recharge the battery by placing the
instrument in its cradle, or replace the battery with a fresh one
with a full charge.
Clock Battery
An internal clock battery is mounted on one of the instrument’s
printed circuit boards. This long-life battery keeps settings in memory
from being lost whenever the Li-ion battery or alkaline batteries are
removed. This backup battery should last approximately five years,
and must be replaced by an authorized RAE Systems service
technician. It is not user-replaceable.
Data Protection While Power Is Off
When the instrument is turned off, all the current real-time data
including last measured values are erased. However, the datalog data
is preserved in non-volatile memory. Even if the battery is
disconnected, the datalog data will not be lost.
