For people using QWERTY keyboards and for those with uncoordinated movements, it is very important to have a telephone that remains steady when they lift or replace the handset and when buttons are being pressed. To meet this requirement a telephone must have some form of non-slip base or pads. There is also a correlation between the weight of the telephone and the type of non-slip base required.

A non-slip base is a desirable feature on any Telephone which is not designed exclusively for fixed mounting. Fixing points which are provided for wall-mounting should, where appropriate, allow for mounting on a horizontal surface for users who require a steady terminal.
