7. ROUTINE MAINTENANCE
The maintenance outlined below should only be carried out once the
main power cable has been disconnected. If you have any problems that
are not covered by the procedures described below, contact Rodenstock
Instruments or your local supplier.
7.1 LED SYSTEMS
1. LED’s typically have a life exceeding 10,000 hours of continuous use and therefore can
be considered as a non-consumable item that will not require changing by a user.
2. Whilst this is a signifi cant life expectancy, we suggest that the Slit Lamp is always
switched off between examinations to conserve energy and LED life.
3. In the unlikely event of an LED failure please contact Rodenstock or your local distributor
for guidance on the replacement procedure.
7.2 REGULARLY INSPECT THE DEVICE FOR DAMAGE OR DIRT
1. Routinely clean as per section 3 on page 6 cleaning instructions.
7.3 CLEANING THE ILLUMINATION PRISM
1. The prism should be cleaned with a soft, clean lens cloth.
2. Care must be taken to keep the objective and the eyepiece lenses clean – use only soft,
clean lens cloths to clean optical surfaces.
7.4 ELECTRICAL CONNECTIONS
1. Routinely check all electrical connections, cables and connectors.
7.5 OPTICS
1. The optics should be wiped clean of any loose dirt or debris with a suitable dust brush
then cleaned with a soft dry lens cloth, washed linen or other non abrasive lens cleaning
material.
7.6 AXLE AND MECHANICAL PARTS
If the Slit Lamp becomes hard to move on the glide plate, the plate should be cleaned with a
lightly oiled cloth or silicon polish. The axle should be cleaned only with dry lint free cloths.
8. WARRANTY
The Rodenstock Slit Lamps are guaranteed for two years against faulty workmanship materials
or factory assembly. Warranty is on a Return To Base (RTB) basis at the cost of the customer
and may be void if the Slit Lamp has not been regularly serviced.
The manufacturer’s warranty and terms and conditions are detailed on the Rodenstock website.
The mirror, main illumination lamp and general ‘wear and tear’ are excluded from our standard
warranty.
