The rechargeable battery gave around 24 hours standby and four hours of continuing calling time. The handset worked at a distance up to 300 metres from the base without any sound deterioration, indoors and out, and dependant on differing conditions.
The handset also had the ability to increase or decrease the volume on other Bang & Olufsen equipment via the built-in remote control. A key lock was built in to avoid the unintentional dialling of telephone numbers when transporting the unit. This phone also had a scrambling function making it almost impossible to ‘listen in’ on calls.
