Safety Precaution
PHILIPS Confidential – Do Not Copy 105S5
6. IMPLOSION PROTECTION.
Picture tubes are equipped with an integral implosion protection system, but care should be taken to avoid damage and
scratching during installation.
7. X-RADIATION.
WARNING: The only potential source of X-Radiation is the picture tube. However when the high voltage circuit is
operating properly there is o possibility of X-Radiation problem, The basic precaution which must be exercised is to keep
the high voltage at the following factory-reco9mmened level.
Note: It is important to use an accurate periodically calibrated high voltage meter.
7-1 The procedure for adjusting high voltage is shown on page 49.
7-2 If high voltage cannot be set to 26KV, immediate service is required the possibility of premature component failure.
7-3 To prevent X-Radiation possibility it is essential to use specified picture tube.
IMPORTANT SAFETY NOTICE
There are special component used in this CRT displays
Which are important for safety. These parts are identified
By the international symbol on the schematic
Diagram and on the replacement parts list. It is essential
That theses circuit parts should be replaced with
Manufacture’s specified parts to prevent X-RADIATION,
Shock fire, or other hazards. Do not modify the original
design or this will void the original parts and labor
guarantee.
