I. Safety Instructions The l ig h tn i ng fla sh w i th arro wh e ad symb ol , within an equilatera l triangle, is intended to alert the user to the presence of uninsulated “ dangerous voltage” within the prod uct’ s enclosure that may be of sufficie nt mag nitud e to consti tute a risk of electric shock to persons.
PRODUCT SAFETY NOTICE 4. Completely discharge the high pote ntial voltage of the picture tube before handli ng. The pi cture tube is a vacuum and if bro ken, the gl ass will explode. 5. When rep lacing a MAIN PC B in the cabinet, always be certai n that all protective are installed properly such as co ntrol knobs, adjustment co vers o r shie lds, barri ers, iso lation resistor networks etc. 6. When se rvicing is re quired, observe the origin al lead dressing.
