Putting into service

Adjusting the headband
The headband can be individually adjusted by simply turning the adjustment screws (1 and 2).
Adjusting the mirror or the high-power optics
Loosen the plastic turning knob (3) on the joint, adjust mirror (4) or the high-power optics (5) and tighten the knob again.
Focussing only possible with ri-focus® CL
The focus can be adjusted by turning the micro-focus where the light emerges (5).

Repairs

Exchanging the glass-fibre cable
Removal of glass-fibre cable:
By opening the plastic turning knob, the clamping unit (6) is opened so that the mirror unit or the lamp head can be removed from the
headband.
Open both brackets (7 and 8) in order to loosen the glass-fibre cable from the headband.
Attaching the glass-fibre cable:
Put the clamping unit (6) onto the ball joint on the headband and fix the mirror unit or the lamp head in place using the plastic turning
knob.
Fasten the glass-fibre cable in the brackets provided on the headband (7 and 8).
Exchanging the leather padding
By opening the press-studs (9) on the leather padding (10), the leather padding can be removed from the headband and replaced by a
new padding.

Recommendations for treating fibre optics headlights

Cleaning, disinfection and sterilisation.
1. Carrying out cleaning, disinfecting and sterilisation:
The fibre optics headlights have to be cleaned immediately after each time they are used. Residues jeopardize the subsequent
disinfection or sterilisation.
1.1 Pre-disinfection: Spray the ring and the cable immediately after use with an aqueous disinfectant solution. Allow time for the
disinfectant to act as recommended by the manufacturer.
1.2 Cleaning: Rub off the cable and ring with a damp cloth.
1.3 Disinfection: The cable and ring should be disinfected only after careful precleaning.
The disinfectant should be applied with a spray bottle or cloth. Use the appropriate concentration and allow time for the disin
fectant to act as recommended by the manufacturer!
Caution: Carefully remove all disinfectant residues from the light input and the optics at the light exit point.
1.4 Gas sterilisation: The cable and ring should only be gas sterilized after cleaning.
For details of packaging in clear film sterilisation packaging and how to perform gas sterilisation, including the obligatory airing
out period, please consult the instructions for use of the gas sterilizer manufacturer. Inform yourself about your gas sterilizer:
60°C and 1 bar should not be exceeded!
1.5 Steam sterilisation: Steam sterilisation of the fibre optics headlights is not possible!
1.6 Care and storage: The fibre optics headlights should only be stored in an absolutely dry condition. The surfaces where the light
enters and exits have to be clean and should not show any signs of moist residues. When rolling up the cable, the minimum
allowed radius of bend of 50 mm is to be observed.
Handling: Caution: Abrupt bending of the cable causes the sensitive glass fibres to break! Repair is then only pos-
sible by exchanging the entire fibre optics cable. For this reason, particular care is required when handling fibre optics headlights, in
order to achieve as long a service life as possible.
Caution: Please avoid abrupt bending of the cable and every form of tension loading as far as possible.
