Notes on Battery Packs

• Battery Pack life will vary depending on handset model and features
and system infrastructure.
• Maximum Battery Pack performance is achieved after a few charge/
discharge cycles.
• If multiple Battery Packs are supplied with your handset, Polycom
recommends that each be fully charged upon receipt to prolong bat-
tery life. Battery Packs will slowly lose charge if unused. To maintain
battery potential, charge unused Battery Packs occasionally or alter-
nate Battery Pack use.
• After a length of time Battery Packs will lose the ability to maintain a
charge and to perform at maximum capacity and will need to be
replaced. This is normal for all batteries.
• Overnight charging is best done while the handset is turned off.
• If the handset does not charge, clean Battery Pack, charger, and
handset contacts with an alcohol swab.
• When the handset is properly seated, the backlight comes on briefly
and the handset beeps to indicate that charging has begun.
• Any battery which exhibits swelling, cracking, or other abnormality
should be disposed of promptly and properly.
• If your Battery Pack requires replacement, contact your system
administrator.
