Compatible with all Uniden DECT 6.0 digital expandable systems, the Uniden DWX207 set includes a waterproof accessory handset and charging cradle. The handset meets JIS7 waterproof specifications, which means it can be submersed in up to one meter (3.28 feet) of water for 30 minutes without damage. This system is also impact and dust resistant, so it can truly stand up to wear and tear.
