17.0 Precautions for Use

WARNING!
In the event of the wheelchair moving in an unexpected way
RELEASE THE SID JOYSTICK/BUTTON or PRESS and
HOLD THE USER SWITCH. This action will stop the
wheelchair under any circumstances.

17.1 Hazards

Do not drive the wheelchair:
1. Beyond restrictions indicated in your wheelchair user
manual, for example maximum inclines, curb height etc.
2. In places or on surfaces where a loss of wheel grip could be
hazardous, for example on wet grassy slopes.
3. If you know that the control system or other crucial
components require repair.
WARNING!
Although the R-Net control system is designed to be extremely
reliable and each unit is rigorously tested during manufacture,
the possibility of a system malfunction always exists (however
the likelihood small). Under some conditions of system
malfunction the control system must (for safety reasons) stop
the chair instantaneously. If there is any possibility that you
could fall out of the chair as a result of a sudden braking action,
it is imperative that a restraining device, such as a positioning
belt, supplied with the wheelchair, is in use at all times when
the wheelchair is in motion. Sunrise Medical accepts no liability
for losses of any kind arising from the unexpected stopping of
the wheelchair, or arising from the improper use of the
wheelchair or control system.
WARNING!
Do not operate the control system if the chair behaves
erratically, or shows abnormal signs of heating, sparks or
smoke. Turn the control system off at once and consult
your authorized dealer. Sunrise Medical accepts no liability
for losses of any kind arising from failure to comply with this
condition.
WARNING!
Electronic equipment can be affected by Electro Magnetic
Interference (EMI. Such interference may be generated by
radio stations, TV stations, other radio transmitters and mobile
phones). If the chair exhibits erratic behavior due to EMI, turn
the control system off immediately and consult your
authorized dealer. Sunrise Medical accepts no liability for
losses of any kind arising from failure to comply with this
condition.
Your wheelchair complies with appropriate National and
International EMC legislation.
For comprehensive instructions and advice on
EMC and EMI conformity, please consult your
wheelchair Owner's Manual.
The wheelchair user must comply with all wheelchair safety
warnings. Sunrise Medical accepts no liability for losses of any
kind arising from failure to comply with this condition.

17.2 Safety Checks

The electronic circuits in your control system have been
designed to be extremely safe and reliable. The on-board
microcomputer carries out safety checks at up to 100 times
per second. To supplement this safety monitoring you should
carry out the following periodic checks.
If the control system fails any of these checks, do not use the
wheelchair and contact your authorized dealer.

17.3 Daily Checks

With the control system switched off, check that the joystick is
not bent or damaged and that it returns to the center when you
push and release it. If there is a problem do not continue with
the safety checks and contact your authorized dealer.

17.4 Weekly Checks

This test should be carried out on a level floor within a clear
and safe area around the wheelchair.
1. Switch on the control system.
2. Check that the Screen/Battery Gauge remains on after
initialization and that the battery gauge is displaying a
reasonable amount of charge.
3. Push the SID joystick slowly forwards or press the SID
forwards button until you hear the parking brakes operate.
The chair may start to move.
4. Immediately release the SID joystick/button. You must be
able to hear each parking brake operate within a few
seconds.
5. Repeat the test a further three times, pushing the SID
joystick slowly backwards, left and right or pressing the
related SID directional buttons.
WARNING!
If these tests are carried out in Latched Drive, be aware that
the wheelchair will move in the direction of the chosen input
signal. You will need to stop the wheelchair or allow enough
space for the Latched Drive to terminate safely.
Do not attempt this test where space is restricted, or it is
unsafe to do so.
