CHANGE OF BATTERIES
Gas-Explorer detectors may be powered by two (2) alkaline
(non-rechargeable)
C-size
batteries (1.5V, Type AM-3) or by two rechargeable batteries sold by Bascom-Turner. The
batteries are good for at least eight, and typically twelve, hours of continuous operation. When
the batteries are drained to about one hour of remaining continuous use, the unit alarms and the
display flashes
"Low Batteries"
between readings. If battery life is over, the unit displays
"Low
Batteries"
and powers down, and the batteries must be changed to make the instrument
operational.
WARNING:
The batteries must be changed in an atmosphere known to be non-
hazardous
.
To change batteries:
1.
Turn instrument OFF.
2.
Remove spent batteries.
a) Unscrew the battery cap and slide out two C-cells.
b) Discard two alkaline C-cells.
3.
Insert two, fresh C-size alkaline batteries.
4.
Replace the battery cap and give it one quarter turn (battery cap bar vertical).
Note that the batteries are inserted with the positive terminal first.
If the instrument does not operate after battery replacement, there is a high probability
that a battery has been inserted with the wrong polarity. Re-insert the batteries taking extra care
to insert each battery correctly.
Note:
Always replace a set of batteries with a new set. When operating in cold weather (below
-10
o
C) use a fresh set of batteries, if possible.

WARNING:
Do not attempt to charge alkaline (non-rechargeable) batteries because
they may leak or vent.
WARNING: Use only alkaline batteries or rechargeable batteries sold by Bascom-
Turner in a Gas-Explorer.
WARNING: To reduce the risk of a battery venting, do not mix old batteries with new
batteries, or mix batteries from different manufacturers.
WARNING: Do not attempt to service the instrument in a hazardous atmosphere.
