Service Manual
Model No.:
12. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
13. Use only an anti-static type solder removal device. Some solder removal devices not
classified as "anti-static" can generate electrical charges sufficient to damage ES devices.
14. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to
damage ES devices.
15. Do not remove a replacement ES device from its protective package until immediately
before you are ready to install it.
(Most replacement ES devices are packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparable conductive material).
16. Immediately before removing the protective material from the leads of a replacement ES
device, touch the protective material to the chassis or circuit assembly into which the device will
be installed.
CAUTION:
Be sure no power is applied to the chassis or circuit, and observe all other safety
precautions.
17. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise
harmless motion such as the brushing together of your clothes fabric or the lifting of your foot
from a carpeted floor can generate static electricity sufficient to damage an ES device.)
