Alternative controllers
You can use the following controllers as an alternative to the controllers with joystick, chin control
or scanning mode described in this operating manual:
• four-button controller
• five-button controller
• head controller
The following chapters provide an overview of the controller function principles. Please see the
documentation provided with the input devices for detailed explanations.
4.13.1 Four-button controller
The four-button controller allows you to control the four movement directions (forwards, reverse,
left, right) using four buttons or keypads instead of the joystick. In addition, you will require an
"ON/OFF" buddy button and a mode buddy button.
Furthermore, you can use the buttons to control the various remote functions such as lighting or
electric seat adjustment.
In addition to normal mode, you can also use the four-button controller in latched mode. In this
mode, a function selected by pressing a button is carried out until you press the button again or
press another button. In this mode, you must use an additional emergency stop button.
4.13.2 Five-button controller
The five-button controller operates in a similar manner to the four-button controller. You can control
the four movement directions (forwards, reverse, left, right) and various remote functions such as
lighting or electric seat adjustment.
