TIP If the power does not turn on
Is the power for the assistant controller turned on?
If the power for the assistant controller is turned on, the power for the controller will not turn on.
In this case, turn off the power switches on both controllers, and turn on the power for the controller.
If the buzzer sounds and the wheelchair does not move
TIP
(a) Was the power turned on with the joystick tilted?
When you turn on the power switch with the joystick tilted, a safety device is engaged to pre-
vent the wheelchair from moving.
In this case, a buzzer beeps (a long "Pi—" sound) and the power lamp (green) flashes.
Release the joystick, turn off the power, and then turn it back on again.
(b) Are you tilting the joystick with the left and right clutches in the manual position?
This is a buzzer to warn you that the clutch has been disengaged. (Beeps "Pi Pi, Pi Pi, Pi Pi")
Turn off the power, switch the left and right clutches to the power drive position, and then turn the
power back on.
If the buzzer beeps while traveling
While traveling, if the load on the motor is too great, a buzzer (long Pi—, Pi—) sounds continuously.
(a) Is the live load too great?
The maximum load is 275 lb for NAVIGO 24" and 220 lb (100 kg) for NAVIGO 16". Do not ex-
ceed the maximum load.
(b) Are you trying to go up a steep slope?
The practical climbing angle is 6 degrees. Choose a travel route that does not exceed 6 de-
grees.
