Safety & Warnings
The manual contains several safety warnings and precautions:
1. Preventing Electric Shock: Before opening the display unit cover, wait more than 1 minute after disconnecting the DC power cable to discharge the capacitor inside the unit.
2. High Voltage Warning: The unit uses high voltages up to hundreds of thousands of volts. Caution is advised when removing the outer cover. Avoid direct contact with high voltage circuitry, especially on the CRT unit and the transmit circuit.
3. Electric Shock Risks: Electric shock of 1000 volts or more can cause instant electrocution and death, and even a shock of 100 volts can be fatal.
4. First Aid for Electric Shock: A stable foothold is essential to prevent further injuries. In case of electric shock, disinfect the burn completely and begin first aid as soon as possible.
5. Insulated Tools: All adjustments should be made using an insulated turning tool to avoid electric shock.
6. Repair Notes:
– Ensure the problem is internal before disassembling the unit.
– Do not open the unit until it is disconnected from the power source.
– Do not force any variable components; turn them slowly and smoothly.
– Do not short any circuits of electronic parts; use an insulated tuning tool for all adjustments.
– Do not keep power on for a long time when the unit is defective.
– Thoroughly read the instructions of the test equipment before connecting it to the unit.
