Quantum: code 222 (hand control is missing or defective)

<div><br>The first two red diodes flashing accompanied by beeping on your Quantum 610 electric wheelchair generally indicates a fault condition or an error code. Here are some possible reasons: Joystick Calibration Error: The joystick may need to be recalibrated. Check your wheelchair's user manual for instructions on how to calibrate the joystick properly. Error Code Identification: The flashing lights and beeping may be an error code. Consult your wheelchair's user manual to interpret the specific error code, as different combinations of lights and beeps can indicate different issues. Battery Issues: Low battery voltage or a battery fault can sometimes trigger error codes. Ensure that the wheelchair's batteries are fully charged and in good condition. Motor or Drive System Issues: Problems with the wheelchair's motors or drive system may prevent it from moving. Check for any loose or disconnected wires in the motor connections. Obstructions: Ensure that there are no obstructions or obstacles preventing the wheelchair from moving. Check the wheels and drive system for any debris. Controller or Joystick Malfunction: A malfunctioning controller or joystick can cause issues. If possible, try using a backup controller or joystick to see if the problem persists. Reset the System: Turn off the wheelchair, wait for a few seconds, and then turn it back on. This may help reset the control system. Technical Support: Contact the manufacturer's technical support or customer service for assistance. They may be able to guide you through additional troubleshooting steps or advise on the next course of action. Professional Inspection: If the issue persists and you are unable to resolve it through basic troubleshooting, consider seeking assistance from a certified technician who specializes in mobility devices. Always refer to your wheelchair's user manual for specific information on error codes and troubleshooting. If you don't have the manual, you can often find it on the manufacturer's website or by contacting their customer support. <br></div>

The undervoltage error on your Edge 3 power wheelchair, especially when encountering inclines, suggests a potential issue with the battery or power delivery system. Error code 34, indicating a bus voltage drop, further points to a drop in electrical power while traversing inclines. This could result from a failing battery, loose connections, or issues with the power distribution system. It's crucial to inspect the battery condition, ensure secure connections, and consult the user manual for specific troubleshooting steps. Professional assistance from the wheelchair manufacturer or a certified technician may be necessary to address and resolve this complex electrical issue.

Error code 72 on a Quantum 4Front wheelchair typically indicates a problem with the joystick or controller. The best way to resolve this issue is to first try resetting the joystick or controller. Here's how to do it:

1. Turn off the power to the wheelchair.
2. Locate the joystick or controller and unplug it from the wheelchair.
3. Wait for at least 10 seconds, then plug it back in.
4. Turn the power back on and see if the error code 72 goes away.

If the error code 72 persists after resetting the joystick or controller, it may be a problem with the joystick or controller itself and it may need to be replaced.
Please be aware that it's important to follow the instructions in the user manual of the device and only use the recommended parts and accessories to avoid causing more problems.
It's also possible that the problem could be caused by a different issue such as a malfunctioning circuit board or motor. In this case, you may want to contact Quantum customer service or a qualified technician to diagnose and repair the issue

This appears to be a Mobility Power Chair Base rather than a Cellphone question, so I moved the category.

It looks like you may have a loose connector. The error is a brake related error

Error 208
Brake No. 1. Overload: current too high
Brake wiring shorted, or brake defective.
Check motor brake connector.
Check brake wiring.
Check brake resistance.
Replace brake.

Check the charge of the batteries first.

i think you will have to ring your support team and carers asap
get someone to test the power control module under the seat or the joystick controller
the batteries must be charged to get the error message
this the quantum pride 610 user manuals

Turning it on and off will reset everything, but I am not sure what you mean by resetting???? The chair is configured for normal operation at the factory and cannot be changed by a layman, unless you buy a hand-held programmer for the particular controller your chair uses. Some/most technicians have these and can change the factory presets using it to reprogram the controller.

Low voltage. Check the batteries and connections to the power module and joy stick. Make sure no loose connections are present.
If problem still persist, then maybe new batteries are needed.
