Regardless of a Non-XL or XL camera model, units that don't receive power for 24 hours will automatically enter dormant mode so that battery can be conserved and low-power shut down be prevented.
A camera will automatically exit "Dormant Mode" when the following occurs:
Camera receives power from the solar panel or auxiliary power supply
Users press the camera's power button on the back
Please Note: It may take several minutes after the camera starts receiving power for it to completely come back online and process queued images.
