* Depending on the installation, as well as a normally closed User Switch, there
may be a user switch integrated into the head array. This switch would connect
to the Omni via the fifth switch pin on the D-type connector.
User switch commands are then used to change drive direction and to enter
the User Menu or to sequence through the other functions on the wheelchair.
There are 3 ways to program the Omni to provide this functionality.
5.1 Double Click Change
A single User Switch operation toggles the direction, while a double operation of
the User Switch will enter the User Menu or sequence the other functions.
This method is selected by setting parameter, Fwd/Rev Auto Toggle to Off.
There is programmability associated with the timing of the double operations.
Refer to section Double Click in the Programming chapter.
5.2 Auto Toggle Change
A direction change will occur if a Forward/Reverse command is operated and
released. A further operation of the Forward/Reverse command will result in
drive in the newly selected direction.
This sequence must be completed within a given time period, typically 2
seconds. However, the parameter, Fwd/Rev Auto Toggle Time, can be adjusted
to give a different time period.
If the sequence is not completed within the time period, the selected direction
will automatically revert to its previous state.
The User Switch is used to enter the User Menu or sequence through the other
functions on the wheelchair.
This method is selected by setting parameter, Fwd/Rev Auto Toggle to On.
For more details, refer to sections Fwd/Rev Auto Toggle and Fwd/Rev Auto
Toggle Time in the Programming chapter.
5.3 Switch Medium Change
A direction change occurs at the instant the User Switch is operated, provided
the parameter Double Click has been set to 0. If the User Switch is released and
