The only maintenance that can be provided by the user is to ascertain

that the optical connectors are free of dust or dirt that could interfere
with light transmission and that electrical connections are secure and
accurate. DANGER! 

Always turn off the transmitter’s power before re-

moving the optical fiber from either the transmitter or receiver unit.

All other questions or comments should be directed to our Customer

Service Department. It should be noted that many “problems” can eas-
ily be solved by a simple phone call.
