VDS Audio handset

This audio handset is made from high impact ABS plastic, with a textured finish for easy cleaning and ultraviolet protection for greater resistance to sunlight.

The 3391 handset has a door release button, volume control and On/Off function for the call tone. It also has an internal magnet that makes sure the arm is well fitted to the base and prevents the telephone falling off and damaging the wall.
