JOYSTICK：
•Self Diagnostic Warning Lights
Flashing of lights indicates there is a problem within power chair. See page 19 for more
information.
•Battery Gauge
There are eleven LED lights on joystick. When all LED lights are on, batteries are
fully charged; The Battery Gauge is used to indicate power on and provides an estimate
of the remaining battery capacity.
Any green LEDs lit indicate well charged batteries.
If only amber and red LEDs are lit, the batteries are moderately charged. Recharge
before undertaking a long trip.
If only red LEDs are lit, the batteries are running out of charge. Recharge as soon as
possible.
•Extendable Bracket
By releasing Knob (B) the joystick bracket (C) is able to extend and retract. With joystick
retracted, this enables you to pull up to any table, and tighten knob (B), when adjusted
to a comfortasle position.
•While the power is ON, press and hold the Power button for 4 seconds.
•The display will turn off immediately.
•After 4 seconds all LED's will flash briefly and the horn will sound a short beep.
•The powerchair will then turn off.
•While SHARK is locked, press the button to turn SHARK on.
•All LED's will flash briefly. The Battery Gauge LED's will then perform a slow right-to-left
chase.
•Press the Horn button twice before the countdown is competed (approximately 10 seconds).
•The current state-of-charge will then be displayed and SHARK may be operated normally.

4.Using the powerchair as a seat in a vehicle.

This Seren Powerchair has been tested to Wheelchair Crash Test standard
ISO 7176/19 using suitable restraints. Wherever possible the powerchair user should use the ve-hicle’s
fitted seats and the wheelchair should be folded away and placed safely in the luggage compart-ment
of the vehicle or restrained.
If it is not feasible to transfer to the vehicle’s seat then the Seren powerchair may be used as a chair
whilst the vehicle is moving with the necessary restraints and with the wheelchair facing the front of the
vehicle.
Drive Devilbiss Ltd recommends that the following types of restraints be used:
a) Buckle and tongue or standard hook restraints for the front of the powerchair,
b) ‘J’ restraints for the rear of the wheelchair,
c) 3-point harness for the user restraint.
The lap belt should be worn across the front of the pelvis, with the webbing fed between the back posts
and armrest.
The upper torso belt should be worn over the shoulder. The belt should be worn as firm as possible
without being uncomfortable. Ensure the webbing is not twisted. For more information on restraints
please contact Drive Devilbiss Ltd
Suitable anchor points on the frame are marked with a small carabiner as indicated below.
Manufacturer instructions and guide lines must be adhered to when fitting both the occupant and frame
restraints.
