7 Electromagnetic interference protection
Electric wheelchairs have been in strict accordance with GB/T 18029-21 standards for electromagnetic compatibility testing. Here we have to point out that electromagnetic wave emitters may interfere with the electronics of electric wheelchairs. Similarly, electronic devices of electric wheelchairs may also interfere with other appliances.

To reduce the effects of electromagnetic interference, read the following warning carefully:
 Warning: An electric wheelchair may interfere with the operation of other equipment within the magnetic field it emits.
 Warning: Electric wheelchairs may be affected by other electromagnetic fields (such as generators or high-power electrical appliances), which may affect driving performance.
 Warning: As long as your electric wheelchair is running, avoid using a portable TV or radio.
 Warning: As long as your electric wheelchair is in operation, please avoid using a walkie-talkie or similar equipment.
 Warning: Check the interference range of the infinite transmitter. Please do not use electric wheelchairs within the interference range.
 Warning: If you are not operating autonomously and you are in a wheelchair or stop, turn off the power immediately to be on the safe side.

The disturbance of the electromagnetic field may adversely affect the operating system of the electric wheelchair, including:
● Failure of electromagnetic brake
● Uncontrolled behavior of electric wheelchairs
● Behavior that occurs when non-users actively control

Electric wheelchairs EMC declaration: Electric wheelchairs must not be used near strong sources of radiation, as this may interfere with normal operation of the equipment. However, it is not limited to mobile phones and electronic article surveillance systems.

Batteries and Chargers
