| Operatoin notice: |
- The machine should have good grounding, gouunding resistance <4 Ohm. According to the international standard, 220V plug in adopts tri-wire rule, the middle wire is the grounding wire.
- The machine adopts high performence, high reliability, steady voltage switch power supply, it has constant voltage overflow protection. It can work in 110~254VAC electric network. The micro-processor are monitoring the output DC voltage. If the Fuse is melted broken, it shows the machine's inner parts has occurred problems.
- In order to make sure reflect loss >/= 45dB, we use FC/APC connector, Other type (such as FC/APC) can not match with it. Keep the connector clean when installing. Clean it using degreased cotton with anhydrous alcohol after several plug-in/out.
- Do not turn on the machine separately or without protection cover at the connector end. Otherwise the laser will do harm to human body especially eyes.
- RF level decides the OMI of the laser and the system index. (CNR, CTB, CSO). When at 59 route PAL-D, its RF level is 20 dBmV. Suppose channel is N,
Si (N) = 20+10Lg (59/N) (dBmV)
- CNR and Channel N : CNR (59) +10Lg (59/N) (dB)
