11.3 THE REMOTE CONTROL
The infrared remote control requires little maintenance.
The trackball element may be cleaned occasionally with a damp (not wet)
cloth. To take out the ball, twist the ring holding the ball anti-clockwise.
Having taken out the ball, you may also clean the trackball interior using a
damp (not wet) cotton swab.
To change the batteries, open the battery holder on the rear of the handset.
Remove the old batteries and dispose of carefully. Insert new batteries of
the type described in the
Technical Data section, observing the polarity
instructions inside the battery holder, and close the snap lock door. Switch
the remote control back on by using the ON/OFF-switch on the right hand
side of the remote. Test that the remote control functions correctly by
pressing the LIGHT key to see if the backlighting operates properly.
