OPERATION
The Joystick Display
The joystick display (see figure 17 on page 22) is a multifunctional visual display.
This display provides three types of information.
1. On/Off status
2. Battery charge level
3. Fault diagnostics
1. On/Off Status
When you turn on the power to your
Compass HD
™
, the LED array will light up
(see figure 17 on page 22).
♦
If the LED array is not lit, the controller and the power chair are not in operating
mode.
2. Battery Charge Level
The joystick LED array is composed of six LED’s.
♦
Two red
♦
Two amber
♦
Four green
When all eight (8) LEDs are lit continuously, there is a full charge on the batteries. As
you use your power chair and the batteries discharge, LEDs in the array will begin to
turn off in descending order. A single lit red LED indicates the lowest state of operable
charge on the batteries. The batteries should be charged immediately.
NOTE:
To ensure a dependable battery charge, we recommend that you charge the
chair’s batteries overnight. Doing this will prolong the life of the batteries and spare you
loss of operational power while you are using your chair normally.
3. Fault Diagnostics
The joystick LED array is also designed to help you diagnose any problems with the
electrical components of your power chair. The LED array does this by flashing on
and off in a coded sequence.
See the table on the following page to see the list of diagnosable problems and the
flash code sequence.
