6.3 Keep dry 

Warning:

• Can not replace the assembly or material of the car.

• Can not arbitrarily increase the weight, so as to avoid imbalance.

• When someone is sitting on an electric wheelchair, no other vehicle can be used.

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

1 safe use and maintenance of the battery

   This product has two batteries, place them under the electric wheelchair, do not need to move.

1.1 Incorrect replacement

The battery may be at risk of explosion. Replace the battery, you can only use the same or the manufacturer recommended the same type of battery, and should pay attention to the battery polarity should be correct.

1.2 Extend the life of the battery is the main point: regular charge, so that the battery is full, if the electric wheelchair disabled, it is best to use the battery enough, such as a long time to disable, the best charge once a month.

2 Charger requirements

Charger for the electric wheelchair internal power supply charge to use when charging, in the electric wheelchair when charging this product can not be used.

3 Specifications of charger

Input voltage：AC 220V

Output voltage：24V/DC

Output current：2.8A

4 Charging steps

The charger provides charging for the electric wheelchair, the main plug is connected to the power supply, and the other charging connector is connected to the lower slot of the controller. Please follow the below instructions to complete the charging procedures:

4.1 Check that the electrical slot under the controller is not blocked.

4.2 Make sure the power switch of wheelchair is off.

4.3 Plug the output plug of the charger into the slot under the wheelchair controller.

4.4 plug the main plug on the charger into the power area, the red power light will light up, the charging process takes about 8 to 12 hours

4.6 Turn off the switch on the charger and unplug the output plug from the wheelchair.

Attention:

Please do not expose the charger to the outdoor heat source, such as radiator, fire, sunshine.

●Do not move the wheelchair until the battery charger plug and the power main plug are unplugged from the wheelchair and power supply. Do not turn on the controller's switch when charging.

●After Charging completes, the charging indicator light turns to "green light", do not stop charging before charging is complete.

●After charging, remove the charger plug, but the longest charging time can not exceed 24 hours, there will be overcharge of the danger.

●Charging time relates to the outside temperature, in the winter needs a longer charging time.

●Observe the following rules to avoid danger when charging:

6) The charger has no waterproof function.

7) Do not charge the charger above the flammable items, such as oil, foot pedal or seat.

8) Lead-acid battery without memory effect, to maintain good charging habits will help extend battery life, over-discharge (less than 1/5 ratio of residual electricity) will reduce battery life. When the battery is in the range of 0 ° -10 °, the normal discharge capacity is 60% of the battery itself.

Controller and system diagnostics

Do not use electric wheelchair before you are fully familiar with how to use this controller. All controller parameters are set by the manufacturer and produce optimum performance in a variety of conditions.
