SAFETY PRECAUTIONS (Continued)
WARNING: EXTREMELY HIGH VOLTAGES, WHICH CAN CAUSE DEATH ON CONTACT, ARE PRESENT IN
ELECTRICAL CIRCUITS OF THE SYSTEM. ALWAYS USE THE FOLLOWING PRECAUTIONS WHEN
WORKING ON THE EQUIPMENT:
1. DO NOT ATTEMPT TO OVERRIDE SAFETY INTERLOCKS.
2. NEVER REACH ACROSS ANY SYSTEM WHICH HAS NOT BEEN TURNED OFF, THE PLUG PULLED AND
HIGH-VOLTAGE CAPACITORS DISCHARGED.
3. WHEN SERVICING LIVE ELECTRONIC EQUIPMENT, ALWAYS WORK WITH ONE HAND IN YOUR
POCKET OR BEHIND YOUR BACK AND STAND ON AN INSULATED PAD (e.g. RUBBER). THAT WAY IF
YOU GET SHOCKED, THE CURRENT WILL NOT PASS THROUGH YOUR BODY.
4. DON'T CARRY ON CONVERSATION OR PERMIT YOURSELF TO BE DISTRACTED IN ANY MANNER
WHILE SERVICING LIVE EQUIPMENT.
5. NEVER SERVICE LIVE EQUIPMENT UNLESS SOMEONE IS IN THE SAME ROOM WITH YOU.
6. NEVER TURN OFF THE MAIN POWER SWITCH IN SOME REMOTE SPOT AND THEN SERVICE
EQUIPMENT WITHOUT ALSO PULLING PLUG ON LINE CORD.
7. IN THE EVENT OF SHOCK, ARTIFICIAL RESPIRATION SHOULD BE APPLIED IMMEDIATELY. IF
POSSIBLE, BY A PERSON TRAINED IN ADMINISTERING SUCH TREATMENT.
WARNING: ALWAYS DISCHARGE ALL HIGH-VOLTAGE CAPACITORS BEFORE ATTEMPTING ANY
SERVICING. DON'T ASSUME THAT THE DISCHARGE FROM A CAPACITOR WILL NOT PRODUCE A
SERIOUS SHOCK. THE DISCHARGE FROM A HIGH-CAPACITY, HIGH-VOLTAGE CAPACITOR IS LETHAL!
WARNING: THE TRANSDUCERS CAN BUILD UP A CHARGE, REGARDLESS OF POWER BEING APPLIED,
DUE TO MECHANICAL SHOCK OR HEAT OF SOLUTION IN CLEANING CHAMBER. THEREFORE, TO
REMOVE SHOCK HAZARD, DISCONNECT TRANSDUCER CABLE AND SHORT THE CABLE TO GROUND
BEFORE SERVICING THE GENERATOR. USE CAUTION WHEN WORKING ON THE TRANSDUCER
ASSEMBLY.
CAUTION: Failure to reconnect wires in their original positions when replacing components in the system
may lead to failure of the system. Carefully note proper arrangement before removing wires from
components to be replaced.
