1. Receive the Dot signal.

2. Place the caps on the red and green lens so that only the blue color is shown.

3. Rotate the blue focus volume on the focus pack and adjust to obtain best electrical focus.

4. Rotate Blue focus volume of focus pack clockwise, so that diameter of the Dot see Caution.

3. Turn on the set.

4. Slowly up the supply voltage from 0V to 135V.

5. Receive dot picture and set PICTURE/BRIGHTNESS to minimum.

6. Slowly up the voltage until hold-down circuit works (picture disappear).

7. Read the HV meter of peak HV voltage. Spec: 34.5±0.75KV

8. If hold-down voltage is less than 33.75KV then solder R1=820K.

9. If hold-down voltage is over than 35.25KV then take-off R514 and solder R1=9.1K.
