Checking hardware
All hardware must be checked at least once a year. Nautel recommends more frequent
checking if the VS300 is subjected to above average thermal cycling, caused by turning the
VS300 on and off.
• To prevent damaging the hardware, ensure that the proper size tools are used. In most
cases, hardware is metric.
• A mounting surface or terminal that has changed colour indicates a loose hardware
connection.
Battery replacement
The VS300's exciter/control PWB contains a battery backup circuit that allows the time and
date to update during ac power failure. The battery should be replaced every 12 months. See
“Replacing the exciter/control PWB battery” on page 3-4.
