First disconnect the power, then use a flat‑head screwdriver to remove the fuse holder and replace the fuse with the specified type and rating.
Verify that AC power is present at the input connector, ensure the power switch is on, and confirm that the correct fuse is installed and not damaged.
Turn on the power, set the voltage knob to the desired value, and ensure the current knob is set below the preset limit; the front‑panel CV indicator will turn green.
Operate the unit at temperatures between 0 °C and 40 °C with relative humidity below 80 % and keep the device well ventilated.
