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.
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.
