Introduction
Batteries to use:
Alkaline batteries:
Toshiba alkaline AA battery LR6 x 4pcs,
Panasonic alkaline AA battery LR6X x 4pcs,
Duracell alkaline AA battery MN1500 x 4pcs,
Energizer alkaline AA battery E91 x 4pcs, or
Varta alkaline AA battery 4106 x 4pcs
Rechargeable batteries:
New Cosmos nickel metal hydride AA battery HR-3UTG x 4pcs
Silver oxide battery (for the clock):
Sony silver oxide battery SR621W x 1pc, or
Seiko Instruments silver oxide battery SR621SW x pc
Ambient temperature: -20ºC to +50ºC
Special conditions of use:
Do not replace batteries when an explosive atmosphere is present.
Do not charge or carry batteries when an explosive atmosphere is present.
Only use the detector while installed in its dedicated elastomer case.
Before opening any parts of the gas detector, ensure that no explosive atmosphere
is present.
The detector must only be charged in a non-hazadous area using the
manufacturer’s charger type BC-10 (with Um = 60 V) and in an ambient
temperature range of 0 to +40 ºC. If the detector is marked for use with T3 only or
both T3 and T4, the user shall check the battery type before charging and only
attempt to charge the detector if it contains NiMh batteries. Detector marked T4
only, shall not be recharged.
The batteries shall only be replaced in a non-hazadous area. All four batteries shall
be replaced together and shall all be of an identical type.
If the detector is marked with both temperature classes T3 and T4, before
deploying the detector in a hazardous area, the user shall check the battery type
via the LCD, and ensure that, if NiMh batteries are fitted, the detector is only used
in areas requiring temperature class T3.
Use of the detector in an atmosphere with greater than 21% of oxygen will
compromise the explosion-proof performance of this detector.
Detector which is marked with temperature class T4 only, shall only fitted with
alkaline primary batteries.
