MAINTENANCE
4.1
Cleaning
It is of utmost importance that the optical apertures of the deflector optical head be kept clean
and free of contamination. When the device is not in use, the apertures may be protected by
a covering of masking tape. When in use, frequently clean the apertures with a pressurized
jet of filtered, dry air.
It will probably be necessary in time to wipe the coated window surfaces of atmospherically
deposited films. Although the coatings are hard and durable, care must be taken to avoid
gouging of the surface and residue of the cleaning solution. It is suggested that the coatings
be wiped with a soft ball of brushed (short fibres removed) cotton, slightly moistened with
clean alcohol. Before the alcohol has had time to dry on the surface, wipe again with dry
cotton in a smooth, continuous stroke. Examine the surface for residue and, if necessary,
repeat the cleaning.
4.2
Troubleshooting
No troubleshooting procedures are proposed other than a check of alignment and operating
procedure. If difficulties arise, take note of the symptoms and contact the manufacturer.
4.3
Repairs
In the event of deflector malfunction, discontinue operation and immediately contact the
manufacturer or his representative. Due to the high sensitive of tuning procedures and the
possible damage which may result, no user repairs are allowed. Evidence that an attempt
has been made to open the optical head will void the manufacturer's warranty.
