Battery (W35 only)

The Ericsson W35 can be powered by a rechargeable battery pack to provide voice service redundancy in the event of a total mains power failure. When mains powered, the Ericsson W35 will keep the battery charged.

Note: The battery is not fully charged when delivered. The charging time for an empty battery is about 4 hours. The battery will not charge if the environment temperature is above 40 degrees Celsius, due to over heating protection.

5.1Installation of the Battery

The battery is available as an accessory and is inserted between the

AC/DC adapter and the Ericsson W35.

5.2Battery Function

If a power failure occurs the Ericsson W35 automatically switches over to battery operation. In order to extend the battery time only voice services is available. Data services, such as USB, Ethernet and Wireless LAN functions will be unavailable.

The Standby button on the front of the Ericsson W3x is red when powered by battery (or when the Standby button has been pressed).

The stand by time is up to 4 hours if no telephone calls are made. Talk time is typically 3 hours. Battery time depends on the mobile network signal quality, battery age, and environmental temperature.
