Risk of unintended movement
When you make a forward or reverse demand,
the wheelchair drives forwards or reverse at a
constant speed and will continue driving at that
constant speed until one of the following occurs:
– the external stop switch is pressed (refer to
5.8.1 External stop switch, page 50),
– the emergency stop is performed (refer to 5.9
Emergency stop, page 57),
– an opposite demand is received (a reverse
demand when driving forwards or a forward
demand when driving reverse) or
– the Latch Drive Timeout has expired.
To avoid potentially dangerous situations Invacare
recommends to make yourself familiar with the
latched driving mode, especially with the demands
to stop the wheelchair.
The term demand, mentioned in this manual, means
the input depending on the type of control, e.g.
joystick movements or sip and puff demands. Refer
to 5.21.7 Using the Sip-N-Puff Head Array, page103
for more information about the Sip and Puff Head
Array.
By default, latched driving mode is pre-set in
combination with a Sip and Puff only and with a Sip
and Puff Head Array. For all other types of control,
latched driving mode is not a default set-up but can
be enabled by your provider.
