the illuminator to cool down for approx. 15

minutes.

• Disconnect the line cable from the line.

• Remove the connection cable of the reflected-

light illuminator from the socket at the rear of

the instrument.

• Turn the cover (4-2/3) to the left and remove it

in backward direction.

• To facilitate the lamp change, loosen the

remove the mount (4-2/2) from the reflected-
