Changing the 6 V 20 W halogen lamp
The following procedure is required to exchange the lamp:
Switch off lamp supply via on/off switch (4-1/
2
)
and allow lamp to cool down for approx. 15
minutes.
Disconnect the earth-contact plug (4-1/
4
) from
the line and remove the flat plug (4-1/
3
) from
the instrument connector (4-1/
2
).
Disconnect the instrument from the line and
place it on the back to make the underside of
the pyramid stand accessible.
Fold down cover (4-2/
2
) and pull out defective
halogen lamp (4-2/
1
).
Use the protective film or a clean paper cloth to
hold the new 6 V 20 W halogen lamp and
insert both lamp pins carefully into the
receptacles.
Do not touch the lamp bulb with your
bare hands; if required, clean the bulb
with clean alcohol
before
switching it
on for the first time in order to avoid
dirt to burn in.
The Standard 25
ICS
is supplied with factory-aligned illumination. The illumination need not be
adjusted even when the lamp is exchanged by the customers themselves.
Fold up cover again, turn the stand upside again and connect the stand to the line.
