explain:

1. Adjust the knob clockwise to reduce the attenuation gradually, and adjust the knob anticlockwise to increase the attenuation gradually

2. Pay attention to the correct alignment between the adjusting tool and the “one” slot of the knob, and then rotate it. Do not push the knob in the box to avoid damaging the device

3. It is recommended that the user connect the test instrument during the adjustment process, control the attenuation range, and try not to exceed 40 dB. If there is no user of the test instrument, please take care not to rotate the knob 26 turns in the same direction, and excessive rotation may cause damage to the attenuator
