To enable wireless operation, the SWEDX Signo & Sandwichboard can be equipped with a battery kit. In battery mode the SWEDX Signo works with the internal media player up to 24 hours in continuous operation. With the BrightSign-Kit an interactive operation up to 15 hours is guaranteed. The battery is supplied with the appropriate power supply unit and is protected against both deep discharge and overcharging. If you combine the battery kit with the motion sensor, the battery operating time increases many times over.
