12.MAINTENANCE of the TWISTED PAIR INTERFACES/KRAMER TOOLS

Do not locate your Twisted Pair Interface/Kramer Tool in an environment where it is susceptible to dust, excessive temperature and humidity. These conditions might damage the electronics, and cause erratic operation or failure. Do not clean your Twisted-Pair Interface/Kramer Tool with abrasives or strong cleaners. Doing so might remove or damage the finish, or allow moisture to build up. Take care not to allow dust or particles accumulate inside unused or open connectors.

NOTES

1.Please note that if the output signal is interrupted by very strong external electromagnetic interference, it should re- stabilize when such interference ends. If not, reset the machine by turning the power switch off and then on.

2.If the recommended actions still do not result in satisfactory operation, please consult your KRAMER Dealer.
