9.2.2 Replacing the Cat. No. 700 Digital Soundhead Exciter Lamp
To replace the exciter lamp, carefully remove the six screws holding the rear
cover/power supply of the digital soundhead. Allow the lamp to cool if necessary.
With the rear cover removed, the lamp will be visible but still attached to the rear
cover assembly by its two supply wires. Slide the lamp out of its base. Carefully
remove a new lamp from the protective box, and using gloves or a clean, lint-free
cloth, replace the lamp in the socket. Be careful not to touch the bulb or inner surface
of the reflector in the lamp. If either is accidentally touched, carefully clean the area
with isopropyl alcohol when the bulb is cool. Slide the lamp back into its base in the
soundhead, replace the rear cover assembly, and tighten the six screws.
