Battery Pack Removal and Replacement
To remove the Battery Pack from the handset, press up on the Battery Pack removal latch on the back of
the handset. The Battery Pack releases outward.
To replace the battery Pack, slide the tab of the Battery Pack into the bottom slot as shown below.
Gently push the top of the Battery Pack until it snaps into place. You should not have to force it against
the handset.
Notes on Battery Packs
• Battery Pack life will vary depending on your handset's model and its features and system
infrastructure.
• Ensure that you fully charge the Battery Pack the first few times, as the Battery Pack becomes
most efficient after the first few charge cycles.
• If multiple Battery Packs are supplied with your handset, Polycom recommends that each be fully
charged upon receipt to prolong battery life. Battery Packs will slowly lose charge if unused. To
maintain battery potential, charge unused Battery Packs occasionally or alternate 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.
