Applying Lubricant to the Battery Terminals
Any time the battery cover is removed, or the battery terminals are accessible, apply a
small amount of lubricant WD40 to the battery terminals at the points where they contact
the battery, using a pen-type applicator such as that shown.

If a pen-type applicator is not available, do not use a spray type applicator directly, but
first transfer a small amount of lubricant to a cotton tip and apply it using this. Be careful
not to alter the shape of the battery contacts.
Applying lubricant in this way can help to prevent the buildup of residue and dirt on the
battery contacts, which may cause incorrect operation. After applying lubricant, replace
the battery and close the battery cap.
