C4.2.1. Precautions for Operation
This section describes the precautions when performing DTSXL System maintenance
and replacement operations.

Precautions regarding Static Electricity
- Always store or carry maintenance parts contained in static-free bags. (When
DTSX3000 parts are shipped from the factory, they are contained in static-free
bags with static electricity warning labels.)
- When performing maintenance, use a grounded wrist strap with a 1M Ω grounding
resistance. Be sure to ground the wrist strap.
- When performing operations on a table, be sure to perform operation on an anti-
static sheet that is properly grounded with 1M Ω of grounding resistance. Be sure to
wear wrist straps when performing operations. Avoid placing plastic items that may
conduct electricity on the anti-static sheet.
- Avoid touching maintenance parts without using conductive sheets or wrist straps.
