Phone Setup
Caution
If the new battery that you use during the hot swap doesn't have a proper charge, a low battery alert displays
and the phone shuts down.
If the internal phone battery isn't awake and charged, the battery hot swap may fail. If the phone was in sleep
mode or if you just turned on the phone, the internal battery may not be awake and charged.
Note
The Webex Wireless Phone 840 and 840S don't have an internal battery, so they don't support the hot swap
feature.
Before you begin
• Make sure that the new battery that you use during the hot swap has a proper charge.
• If the phone was in sleep mode or if you just turned on the phone, wake and charge the internal battery:
Procedure
Step 1
Remove the battery.
Step 2
Within 60 seconds, install the new battery.

Battery Contact Damage Prevention
If you slide or drag part of the battery over the battery contacts during insertion or removal, it may damage
the battery contacts.
Damaged battery contacts that can't make proper contact with the contacts in the phone, may cause issues
such as:
• The phone won't power on.
• The phone shuts down randomly.
1. Choose one of the following:
• If the phone screen was in sleep mode, unlock the phone and wait for 30 seconds.
• If you just turned on the phone, unlock the phone and wait for 3-5 minutes.
2. Briefly press the Power button to turn off the phone screen and wait for 3-5 seconds.
