General information

Use the User Manual, SAP No.: 1165-216, as additional

lite

rature on the

VISUCAM

lite

fundus

camera. You must be familiar with the contents of the user manual to be able to work with the

service instructions.

The service manual mainly covers the defined spare parts and the description of how the most

important components are replaced.

The replacement modules have been chosen in such a way that replacing them should be

possible without a special training. If in-depth work on the unit is necessary, you should attend

the appropriate service training.

The VISUCAM

lite

fundus camera does not have to be installed by service staff. For this reason,

no Service Report is necessary.

No fastening components are allocated to and supplied with

the spare parts. For

this reason,

the fastening components provided in the unit must be re-used when modules are replaced.

Caution:

After the unit has bee

n opened, haz

ardous voltag

es are accessibl

e. Take the

necessary precautions against the coming into contact with hazardous voltages and

comply with the applicable work instructions.

Cleaning Care and Servicing of the unit

Also see the Care an

d Maintenanc

e chapter in the use

r manual.

The unit requires almost no servicing. We recommend having the unit serviced once a year on

the basis of

an appropriate support contract.

The points listed in

the "System check" chapter represent a

work plan which must be

completed

when a unit is serviced.

The optical surfaces can be

cleaned using an ether-methylated spirits mixture (9:1), a

special

optics cleaning mixture (SM-30-8005-32) or methanol.
