Page 12 Always use eye protectors (goggles) such as 25072 (goggles in the Common Tool Kit LTT 601 044/1) when drilling. Flying chips and dust may get into your eyes. 12 (158) LZN 302 14 P3A-1 © Ericsson Radio Systems AB 1999-11-10 — All Rights Reserved —...
Page 13: Electrostatic Discharge, Esd
The resistance value is low enough to discharge the electrostatic voltage. Never replace the cable with any other cable. The ESD wrist strap must be connected to earth. Ericsson recommends wrist strap LYB 250 01/14. Storing and Transporting printed board assemblies and IC Components Use the original packaging.
