1.3
Maintenance, Cleaning and Service
The Heidelberg Retina Camera is a precision optical instrument. Protect the instrument
against dust and moisture, and avoid shocks and the action of strong forces.
Beyond the procedures described in this chapter, the operator should not work on the
instrument. Please be aware that only authorized service personnel can do service and
repair of the HRC device. Do not open the camera or power supply unit. If the device is
opened by someone other than an authorized service personnel, the warranty will be
discontinued. For maintenance, adjustment and repair of the equipment contact
Heidelberg Engineering or your local distributor.
A yearly inspection of the device by a Heidelberg Engineering service engineer is highly
recommended to ensure proper and exact operation.
1.3.1 Cleaning and Disinfection
Before cleaning the instrument, turn the instrument off and disconnect the power plug.
The lenses should be carefully cleaned at regular intervals. For this purpose, it is best to use
a cotton swab slightly moistened with 99% ethanol. Do not use disinfection alcohol for
cleaning the optics, as deposits may remain on the lens surface.
The non-optical surfaces of the instrument can be cleaned and/or disinfected as necessary.
Any standard cleaning product appropriate for plastic surfaces which does not contain
acetone or hydrogen peroxide (e.g. ethanol and isopropyl alcohol disinfectants) may be
used for this purpose. Make sure that no cleaning agent penetrates into the equipment.
1.3.2 Changing the Fuse
WARNING:
Before changing a fuse the HRC must be switched off and disconnected from the
mains!
The fuses are located in a cartridge (1) in the socket for the mains supply (2) at the back of
the power supply unit.
Remove the cartridge by inserting a small screwdriver behind the flap of the cartridge and
lift the cartridge out of the fuse socket. After exchanging the fuses, insert the cartridge into
the socket.
IMPORTANT: Only fuses with the following specifications are to be used:
100 V-240 V: 2x T 2.0 AL; Size: 5 x 20 mm each, 2-pole fuses.
Always exchange both fuses.
