Remark
1. After the first attenuation adjustment, operators should stop and wait for about 3-5 seconds
to get the finally stable attenuation, since the release of the inside electrical part will cause
±0.3dB attenuation fluctuation.
2. Confirm the required attenuation again and finally draw glue to the adjusting knob to fix it.
