Switch off the lighting system and let it cool down (risk of burning). During replace-
ment of the lamps the patient must not be touched as it is possible to come into con-
tact with parts under tension.
Release and remove sterilizable handle.
Unscrew the knurled screw on the underside of the light by turning anti-clockwise.
Pull out the whole light system at the hand grip.
Remove a faulty halogen lamp. We advise users to insert the reserve lamp into the
main light lamp holder , marked with <R>, and to insert the new halogen lamp in the
reserve lamp holder so that the reserve lamp does not become too worn.
Fit a new halogen bulb into the bulb holder, - for the booking reference number see
paragraph 3.3.2 halogen bulb on page 19 - ( do not touch the quartz cone of the halo-
gen bulb with your bare fingers, use a cloth or soft paper). During a lamp change
check the bulb holder for scorch marks. If scorch marks are present, inform our
service department.
Fit the light system back into the holder (picture 4) an screw up the knurled crews in a
clockwise direction.
Switch the lighting system on and check that the lamp is on and the red indicator light
is off.
Note!
Only use original BERCHTOLD halogen bulbs. If other bulbs are used, all guarantees regarding per-
formance and operation will lapse.
