[3] Precautions for assembly

1. Points to be checked and precautions when servicing the unit

Mount the main PWB Ass’y on the backlight chassis and check that the EMI-prevention parts are not peeled and twisted from the access holes. (The
EMI-prevention parts, conductive nonwoven fabric gaskets, must be seen from the access holes.)

[Countermeasure]

Attach the conductive nonwoven fabric gaskets on the shielded case on the main PWB.

PMLT-A678WJQZ

Attach the conductive nonwoven fabric gasket on the RF terminal angle.

(PMLT-A680WJQZ)
