Chapter 1: Codan Radio Maintenance Page 2
RECOMMENDED MAINTENANCE SCHEDULE
Codan Communications does not recommend any specifi c maintenance schedule for our MT-4E
radio systems. Many organizations have annual preventative maintenance scheduled as part of their
standard maintenance procedures; other organizations will only maintain the radio system when a
system failure occurs; and other organizations will use a combination of preventative maintenance and
maintenance for failures.
REPAIR NOTE
The MT-4E Radio System employs 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 specifi cally 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.
ESD - ELECTROSTATIC DISCHARGE
Static Electricity can damage electronic equipment, causing it to stop functioning immediately, or
degrading it, leading to breakdown later. Static sensitive parts should be handled by technicians
grounded with wrist and/or two heel straps. Transferring of ESD sensitive components to or from
diff erent areas should be conducted in ESD safe bags, tote boxes or carts.
