Some telephone
handsets have keys positioned on the handset. This can cause difficulties
for persons with poor manual dexterity or reduced strength. A
person having difficulties holding a handset is likely to press
keys by mistake.
It is better
for the keypad to be positioned on a surface that does not have
to be held.
People with
impaired hearing will need to adjust the handset position to obtain
the clearest speech, especially when an inductive coupler is being
used. Having found this position, it is most inconvenient to have
to move the handset to re-dial or to respond to automated dial-in
instructions. |
