12 Platinum Sound Processor User Guide
Please note that if a partially charged battery is placed in the charger,
the battery may be fully charged in a lesser period of time. The
battery can be removed at anytime. The battery charger and batteries
will not be damaged if the batteries remain in the charger longer than
the required charging time (approximately 2.5 hours). It is a good
idea to use the batteries on a rotating basis to maximize battery life.
Batteries can be labeled (e.g., 1, 2, 3, etc.) to keep track of the
rotation.
CAUTION: The battery charger is used for charging the battery
provided only. It cannot be used to charge off-the-shelf AA batteries.
The rechargeable battery pack and battery charger contacts should be
kept free from dirt and dust. Dirty contacts can result in battery
charger malfunction. Clean the contacts at least once a month using
an alcohol swab.
If the battery charger is dropped, inspect the device for evidence of
damage or cracking. If any evidence of damage is seen, the battery
charger should be replaced. Prior to use, you should inspect the
battery charger power cord to ensure that it is not frayed or damaged
and that the plug is not broken. If your power cord appears to be
damaged, it should be replaced.
