to gently brush away dirt on the contacts.
• If dirt or residue cannot be removed with an eraser, use an alcohol swab or soft cloth
dampened with alcohol.
Warning: Use only alcohol. Do not use any other cleaning solvent. Carefully clean one
contact at a time, and make sure contacts are completely dry before using the charger.
• If the abnormal condition persists after cleaning the contacts, try various combinations of
batteries and chargers to determine if the condition is specific to the battery or to the
charger.
• If the condition is specific to the battery, give the battery to your system administrator.
• If the condition is specific to the charger, disconnect the charger from its power source for
about five seconds, then reconnect it. Test the charger with a battery. If the abnormal
condition persists, return the charger for service.
