Charging
Safety Hub housings should be cleaned or decontaminated as necessary to remove any dirt or
debris that may be present before placing in the Docking Station. Up to four hubs can be
placed in a single dock. A full charge cycle for the hub batteries can take up to 4 hours.
Charge only using approved 3M equipment. Do not charge outside of the operating
temperature range.
NOTICE: Always disconnect Safety Hub Docking Station from power prior to cleaning contacts. Use
caution when cleaning near contacts so as not to bend the contacts. Do not insert foreign objects into
charging wells to prevent damage to the charging contacts.
