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 nickel metal hydride (NiMH) batteries sold
by Bascom-Turner. The batteries are good for at least eight, and typically ten, 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. The batteries must be changed to make the instrument
operational again.
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 or recharge the NiMH cells.
3.
Insert two, fresh C-size alkaline batteries or two charged NiMH C-sized cells.
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. Alkaline batteries have shortened life in cold
weather; NiMH batteries are recommended.
WARNING:
The batteries must be changed in an atmosphere known to be non-
hazardous
.
WARNING: Do not attempt to charge the 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.
