REPaIR notE

MT-4E Receivers and Transmitters employ a high

percentage of surface mount components which

should not be removed or replaced using an

ordinary soldering iron. Removal and replacement

of surface mount components should be

performed only with specifically designed surface

mount rework and repair stations complete with

Electrostatic Discharge (ESD) protection.

When removing surface mount solder jumpers, it

is recommended to use solder wick braid in place

of vacuum-type de-soldering tools. This will help

prevent damage to the circuit boards.
