HandlingStatic‐SensitiveCircuits/Devices:Whenhandlingthetransmitter,thetechnicianshouldfollowthese

guidelines to reduce any possible electrostatic charge build‐up on the technician’s body and the electronic

part.

1. Always touch a known good ground source before handling the part. This should be repeated while
