Page 3: Safety Precautions
Safety Precautions The following are general safety precautions that are not necessarily related to any specific part or procedure and do not necessarily appear elsewhere in this publication. Keep Away From Live Circuits Operating personnel must at all times observe general safety precautions. Do not replace components or make adjustments inside equipment with the high voltage supply turned on. -
Page 4: Warning Statements
Warning Statements The following safety warnings will appear in the text and are repeated here for emphasis. WARNING When power is in the upper range of the load’s capacity, the radiator will become hot - care should be used in touching the equipment. WARNING Do not attempt to disconnect these loads from the coaxial cable while RF energy is still being applied. - Page 5 BENUTZUNG WIRD DAS GERÄT AUF ANDERE WEISE VERWEN- DET ALS VOM HERSTELLER BESCHRIEBEN, KANN DIE GERÄTESICHERHEIT BEEINTRÄCHTIGT WER- DEN.
