Warning: To reduce the risk of ignition of hazardous atmospheres, recharge the battery only in areas known to be non-hazardous. Remove and replace the battery only in areas known to be non-hazardous.

Remove the three Philips-head screws to open the compartment.

Insert four fresh AA batteries as indicated by the polarity (+/-) markings.
