1. Safety precautions
WARNING
The maximum load weight for this device is 253.5 lb (approx. 115 kg). It
includes both the occupant and any luggage. Use the device without subjecting
it to a load higher than this limit.
There is a risk of damaging the device.
Do not sit on the controller, place the controller on the ground with the device folded, or apply
an excessive load to the controller. Do not press the controller or switches with excessive
force or operate them with a sharp object.
There is a risk that the controller may be damaged, rendering the device inoperable.
Do not jump onto the foot rest, stand on the foot rest, or place an excessive load on the foot
rest.
There is a risk of the device lifting up and tipping.
Do not ride on the foot pedal between the anti-tip rollers.
There is a risk of tipping over. The device may lose its anti-tipping functionality if the anti-tip
rollers and foot pedal are deformed. The anti-tip rollers and foot pedal must be replaced if they
are deformed. Contact your dealer or technical support.

2. When getting in the device and driving the device
WARNING
Turn off the device power when getting in and out of the device.
There is a risk of unexpected movement of the device caused by accidental contact with the
controller.
When driving, fully check the surroundings and road conditions. Drive carefully at low speed
particularly when driving in locations crowded with people, close to walls or other locations
where there are obstacles nearby, and in narrow places or on uneven surfaces or slopes.
Otherwise, there is a risk of accident. When driving on wet inclines, there is a risk that the
device may loose stability. Pay close attention when driving.
When approaching curbs, steps, slopes, and similar obstacles, approach at a 90° angle and
drive over them carefully at low speed.
There is a risk of tipping over or deforming the drive base.
Be sure to lower the foot rest while driving. Also, keep your feet on the foot rest, and prevent
your feet from extending outside the width of the foot rest.
Otherwise, there is a risk that your feet may get caught in the front wheels.
When stopping on a downhill slope, release the controller early, and make sure that the device
stops with an ample amount of extra space around it.
The stopping distance is longer when on a downhill slope. There is a risk that you may be
unable to stop in the intended position, causing an accident.
Release the brakes only when on a at surface and in emergencies after turning off the power.
After moving the device manually with the brakes released, raise the brake release levers and
lock the brakes.
There is a risk accidents may occur because the device will move freely when the brakes are
released.
Do not drive the device in the following areas.
The device may tip over and there is a risk of accidents.
• Escalators or stairs
• Steps higher than approximately 1.4 inches (35 mm)
• Slopes with a gradient of 10° or more
• Soft surfaces such as sand or mud
• Snowy or frozen paths
Do not release the brakes and move the device manually except in emergencies.
There is a risk accidents may occur because the brakes do not work.
While riding the device, do not crouch down, lean out of the device, or exercise. Pay attention
to the center of mass while driving.
There is a risk the device stability and balance will be affected. Request help from those around
the device before reaching for inaccessible objects.
Do not drive while holding something in your hand or with something placed on your lap.
There is a risk of unintended movement of the device.
Do not go off curbs or steps that are higher than approximately 1.4 inches (35 mm)
This may cause the anti-tip rollers to catch on the step and the device may no longer be able to
be driven.

1.1. EMI (Electromagnetic Interference)
There is a risk of unintended movement of this device as a result of radio waves. Avoid driving in an area where
strong electromagnetic waves are generated such as areas around high-tension wires, television towers, etc. Radio
waves may interfere with the control functions of this device.
The device may also emit its own electromagnetic fields and may disturb the operation of other nearby devices.
To reduce the chance of unintended device movement, which could result in serious injury, pay careful attention to
the following instructions.
• Do not operate hand-held transceivers (transmitters receivers), such as citizens band (CB) radios, or turn
on personal communication devices, such as cellular phones, while the device is turned on;
• Look for nearby transmitters, such as radio or TV stations, and try to avoid coming close to them;
• Be aware that adding accessories or components, or modifying the device, may make it more susceptible to
EMI.
If the device moves or stops when the device controller is not operated, or if the device operates in a way different
than intended, take the following actions.
• Turn off the device as soon as it is safe.
• Record the controller operation that was being performed at that time.
• Record the device operation that could not be activated using the controller.
• Record the mobile phones and other electronic devices that may be sources of radio waves and were near
the device.
Based on these notes, consider the possible cause of radio frequency interference and remove it. If the problem is
still not resolved, consult with your dealer or customer support. Keep your earlier notes handy while talking with
them.
If radio frequency interference is suspected, turn off the power and disconnect the battery.
1.1.1. General Q&A on EMI and RFI
The following are general questions and answers regarding steps to avoid nearly all of the effects of EMI and RFI
with this device. Please use them as reference.
Where do radio waves come from?
Radio waves are emitted by unidirectional or bidirectional radio devices. Such devices include transceivers,
mobile phones, wireless computer links, microwave generators, and radio call transmitters. Radio waves are a
form of electromagnetic energy, and the strength of the energy increases at closer distances to the transmitting
antenna. This electromagnetic field can cause problems for users of electric equipment.
What kind of movements should I expect if the device is affected by EMI or RFI?
EMI and RFI undergo extremely large dynamic changes and may affect a device depending on conditions such as
the following.
• Radio wave frequency and strength

11
WHILL Model F User Manual

1. Safety precautions
• Structure of the power supply equipment
• Inclination of the device (whether the ground is flat or slanted)
• Whether the device is turned on and whether it is moving
If this device is affected, there is a possibility of abnormal movement. It may begin moving uncontrollably or stop
suddenly. Strong EMI or RFI can damage the control system.

This electrical medical equipment needs special precautions regarding EMC and put into service according to the
EMC information provided in the user manual; The equipment conforms to this IEC 60601-1-2:2014 standard for
both immunity and emissions. Nevertheless, special precautions need to be observed:
• The equipment with no ESSENTIAL PERFORMANCE is intended for use in the home healthcare environment.
• WARNING: Use of this equipment adjacent to or stacked with other equipment should be avoided because it
could result in improper operation. If such use is necessary, this equipment and the other equipment should be
observed to verify that they are operating normally.
• The use of accessories, transducers and cables other than those specified or provided by the manufacturer of
this equipment could result in increased electromagnetic emissions or decreased electromagnetic immunity of
this equipment and result in improper operation.
• WARNING: Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the Model F, including cables specified
by the manufacturer. Otherwise, degradation of the performance of this equipment could result.
• WARNING: If the use location is near (e.g. less than 1.5 km from) AM, FM or TV broadcast antennas, before using
this equipment, it should be observed to verify that it is operating normally to assure that the equipment remains
safe with regard to electromagnetic disturbances throughout the expected service life.
• When the AC input voltage is interrupted, the equipment will stop battery charging and if the power supply
restored, it could be recovered automatically, this degradation could be accepted because it will not lead to
unacceptable risks and it will not result in the loss of basic safety or essential performance.
During all immunity tests, a digital tachometer was used to monitor the rotating speed of wheel and a clamp meter
was used to monitor the output current of battery charger to verify the performance of EUT.
