The CEW has a real-time clock powered by the battery pack and an internal battery as well. The CEW should keep accurate time even when the battery pack is removed.
The X2 CEW is programmed to GMT at the factory. Every time the X2 CEW is connected to Evidence.com services, the system will perform a time synchronization to GMT. The conversion to local time, including adjustments to daylight savings time, are all computed in the PC-based software. There is no need to program the X2 CEW to local time or to reprogram the CEW to daylight savings time.
If you do not have an Evidence.com account, the CEW will synchronize with your local computer's time.
