Information on electromagnetic compliance (EMC)
Since electromagnetic disturbances become stronger the closer you get to
emitting aerial, electromagnetic fields from portable radio sources are of
particular significance. It is possible for high levels of electromagnetic
energy to accidentally come too close to a control system whilst these devices
are in use. This can affect the braking and pushing aid’s movement or braking,
so please observe the following recommendations in order to avoid adversely
affecting the functioning of your braking and pushing aid:
The following warnings should reduce the risk of accidentally triggering braking or forward motion of the braking and pushing aid, which could lead to serious injury.
- No use of portable transmitting/receiving devices such as CB radios or other portable devices in operational mode, e.g. mobile phones, whilst you’re braking and pushing aid is switched on.
- Beware of nearby transmitters, e.g. radio and TV transmitters, and try to avoid them.
- Should the brakes accidentally be applied or should the eWalk accidentally move forwards, and then switch it off as soon as it is safe to do so.
- Note that adding accessories and components or modifying the braking and pushing aid may make it more liable to react to electromagnetic waves.
- Tell your dealer about any unintentional movements and braking, and determine whether there are any sources of electromagnetic radio disturbance nearby.
NB: The e-walk itself can also cause disturbances as a result of electromagnetic fields. If you observe any such disturbances, remove the e-walk from operation and tell your dealer or notify Decon Wheel directly.
General information

Fitting
Fitting the adapter plates
Since you can attach the eWalk to all common types of wheelchair using
different adapter plates, the adapter plate attached to your wheelchair may
differ from the one shown in these instructions.
To make the eWalk function with your wheelchair, the appropriate adapter
plates must be attached. If there are drill holes in the wheelchair frame,
these must be used to attach the adapter. If there are none, clamp adapters
must be used. This makes it possible to remove the eWalk from the wheelchair
completely and without leaving anything behind, and if necessary use it again
with another wheelchair.
NB: Only authorised dealers should fit adapter plates and carry out adjustments.
Illustration 4:
