Turn off the power switch and disconned the power cord and other cables from the
instrument.
14.2.1 Removing a Grating:
Refer to the Optical Components: Changing Gratings sedion and follow the
instrudions until the point where the grating or turret is removed. Then cover the
grating using only the grating cover that was shipped with the instrument. To prepare
a cover, apply a strip
of
vinyl eledrical tape along each side, leaving a 1/2"
(1
cm) flap
extending beyond each side. Exercise extreme caution to avoid contading the grating
surface. Tilt the cover so that the bottom edge slips under the grating first, then gently
rotate the top of the cover until the grating is fully covered. While holding it
in
place,
secure it by sticking the tape flaps to the sides of the grating mount. Do the same for
each grating

out the baffle from between the circuit boards and the mirror mounts. From the
outside of the rear wall remove the screws holding the board spacers and lift the
board(s) out of the instrument, disconneding and noting
connedor
locations for the
cables as you go. Pack the board(s)
in
an antistatic bag for return

the walls.
Wrt:h
care
to
avoid contading the mirror surface, secure the mirror assemblies
to
the side
walls with nylon cable ties or an equivalent. There are attachments provided on the
baffles for this purpose.
