NOTE:
-
For the detection diode (D401: HSM276SR), the withstanding static voltage is very low. So, pay special
attention to static electricity to protect the diode from electrostatic damage when servicing.
-
When the detection antenna has been removed from the upper case for servicing, be sure to stick it
onto the upper case with adhesive tape along the guide, after the repair is completed.
