DEGAUSSING SHIELDS ALSO SERVE AS X-RAY SHIELD IN COLOR SETS.
ALWAYS RE-INSTALL THEM.
AFTER THE ORIGINAL SERVICE PROBLEM HAS BEEN CORRECTED, A CHECK
SHOULD BE MADE OF THE FOLLOWING:3. IT IS ESSENTIAL THAT SERVICE PERSONNEL HAVE AVAILABLE AN ACCU-
RATE AND RELIABLE HIGH VOLTAGE METER. THE CALIBRATION OF THE
SUBJECT:FIRE & SHOCK HAZARDMETER SHOULD BE CHECKED PERIODICALLY AGAINST A REFERENCE
STANDARD. SUCH AS THE ONE AVAILABLE AT YOUR DISTRIBUTOR.
