3. Putting in operation

● Before commissioning the chair, remove the packaging and protective
plastic wrap.

● The type of chair (and options) is marked on the packaging and the list of
accessories is included in the documentation.

Note! Please check that the chair accessories (remote control

handset, armrest strap and headrest pillow) are present and
complete.

• The motor actuating rod of the legrest is to be connected to the legrest

frame using the pin supplied, according to the illustration. Secure the pin
using the washer and fixing ring. (Figure 1)

Figure 1

● Check whether the handset connection plug is appropriately inserted into
proper connector of electronic control unit (Figure 6/a; 6/b) found under the
seat.

● Check the local mains voltage against the value indicated on the data plate
of the chair before use. If the voltage matches insert the electrical plug into
a mains outlet.

Before switching the chair on, it should be checked whether
condensation (possible with a temperature change) is present on
any electrical components. If there is condensation, then the chair
has to be allowed to reach room temperature.

The control box does not work without closing plug, that should be
connected tightly into this socket (Figure 6/a; 6/b)

 Attaching the upholstery:

Using the handset, adjust the chair in such a way that the legrest is in line
with the seat plate and the backrest is vertical (Figure 2). This is the easiest
position in which to attach the upholstery.

There are two straps on the back of the upholstery. These have to be
pulled onto the frame (Figure 3, Figure 4).

With the velcro straps found on the two sides of the sitting part of the
upholstery, secure the upholstery to the frame (Figure 5).

 Attach the headrest pillow to the backrest with the velcro straps. Secure the

armrest strap included in the accessories to the armrest. The armrest strap
is used to position the remote control handset.

● Check whether the motors work properly with the help of the handset.

● Position the chair such that sufficient space is available to enable

unhindered adjustment of the chair in any position and access from all
sides.

Check whether the power or the handset cable is not stretched or
ends up under the wheels or another object while operating the
chair.

4. Operating the chair

4.1 Armrest adjustment

The height of the armrest can be adjusted by pulling the indexing plunger on the
telescoping rail, moving the armrest up or down and then pushing it back again.
By loosening the knurled knob directly under the armrest, the armrest can be
cantilevered and slipped up and down along its longitudinal axis. The distance
between the armrests can be adjusted by rotating the armrest.

The enhanced mobility of the armrests makes it possible to comfortably seat
differently sized patients. Folding the armrest up to the backrest facilitates
entering the chair from the side. (Figure 7)

Figure 7 Telescopic armrest

4.2 Use of the handset

The adjustment of the chair is done by using the handset (Figure 8/a; 8/b). The
chair moves only as long as a button of the handset is depressed. The control of
the chair makes it possible that more than one motor is active at any time.
Depressing any button is signalled by a green LED on the handset.

More than two minutes of uninterrupted pressing of the button
should be avoided!

The chair can be set into the Trendelenburg position from any
position within a very short space of time by pressing the red
button on the handset.
