Safety & Warnings
DANGER! HIGH VOLTAGE
High voltages of up to hundreds of thousands of volts are used in this unit. BEWARE of high voltage when removing the outer cover of the unit. When working on the interior, avoid direct contact with the high voltage circuitry especially on the CRT unit and the transmit circuit.
Electric shock of 1000 volts or more causes instant electrocution and death; and, even an electric shock of only 100 volts can kill you.
To avoid electric shock, all adjustments should be made using an insulated turning tool.
FIRST AID IN CASE OF ELECTRIC SHOCK
A stable foothold is essential to prevent more extensive or additional injuries. When injured by electric shock, disinfect the burn completely and begin first aid as soon as possible.
REPAIR NOTE
1. Make sure a problem is internal before disassembling the unit.
2. DO NOT open the unit until the unit is disconnected from the power source.
3. DO NOT force any of the variable components. Turn them slowly and smoothly.
4. DO NOT short any circuits of electronics parts. An insulated turning tool MUST be used for all adjustments.
5. DO NOT keep power ON for a long time when the unit is defective.
6. READ the instructions of the test equipment thoroughly before connecting equipment to the unit.
