Battery Exchange
The rechargeable batteries in the different S850i components can all be exchanged. Please note that only Aastra
approved batteries should be used for the replacement. The following sections explain how to change the batteries in
the different components.
We recommend charging any component for eight hours after exchanging the battery.
Microphones
To exchange a Microphone battery push the bottom part of the back cover slightly down towards the Charger Tray port
and then lift it as shown in the illustration below.
Carefully take the battery out of the plastic cover. Put the new battery into the back cover as shown in the figure below.
Press on the battery until it snaps into the back of the Microphone housing.
Slide the back of the Microphone back in place. Place the Microphone back into the Charger Tray. The LED should go on
indicating the charge status of the Microphone.
