Environmental Conditions
Use the power wheelchair outdoors with great caution when the temperature is below or near freezing. Ice surfaces may have formed, which could lead to loss of traction in drive mode (and thus to an emergency stop) or slipping on the stairs.
Do not leave the BRO in temperatures below freezing for a long time (e.g. in the car in winter). If the battery freezes, it is not possible to switch to drive mode until the battery has thawed again.
Do not allow the BRO to remain in temperatures exceeding 40°C for long periods of time (e.g. in full sun in a car in summer). If the battery overheats, you cannot switch to drive mode until the battery has cooled down again.
On very hot days, the battery can overheat and the device will stop automatically. You can then only continue your journey once the battery has cooled down again. On very hot days, avoid going uphill over long distances or taking long flights of stairs.
Never go through water that comes up higher than the underside of the tracks. This could damage the electronics and the wheelchair could come to an abrupt stop.
Switch on the wheelchair lights at dusk and at dawn so that other road users can see you.
Avoid taking the wheelchair on slippery surfaces (snow or ice, loose surfaces such as gravel or sand) wherever possible. However, if you have to, reduce your speed and proceed with utmost caution.
Protect the wheelchair from moisture, including rain, snow, mud or splashes of water. Moisture can cause a short circuit and the wheelchair may catch fire, resulting in injury or damage to property. If the wheelchair has been exposed to moisture, do not use it until it is completely dry.
Replace the cover or joystick protector immediately if it shows signs of cracking or wear. Otherwise moisture can penetrate through to the electronics and cause injuries or damage to property, including fire.
Surfaces may get very hot under certain circumstances as a result of external heat sources (e.g. sunlight). Check the temperature before touching the surfaces and if necessary let BRO cool down in the shade.
Adjust the volume of the acoustic alerts to suit ambient noise levels. You might otherwise miss them if it is loud.
Always adjust your speed to the conditions around you. Thresholds and holes are more difficult to see, especially at dusk or in the dark, potentially leading to an accident. For this reason, always proceed slowly and with particular care in difficult conditions, such as limited visibility, so that you can detect obstacles and avoid them in good time.
