The BT Freeway FM Twin Two Way Personal Mobile Radios are a calling system made by BT. These radios are designed for personal use and come with 2 x Charger Docks for convenience. The Freeway FM model offers reliable radio communication for various communication needs. Perfect for walks, hikes, or outdoor activities, these mobile radios provide a secure and efficient way to stay connected on the go. Not used for a long time and not tested. Rechargeable batteries may be ok but replacement I understand are available for around £7 each. Alternatively, standard AAA batteries can be used.
