Many transceiver problems can be attributed to environmental conditions (including vibration), which can

loosen cables and permit moisture to penetrate the connectors. It is highly recommended to seal the

connectors using a technique similar to the one described below. This will provide moisture protection and

keep the connections tight. For your convenience, VCom has provided two 6 inch lengths of rubber self-

amalgamating sealing tape to use on the two connections of the TR850.

STEP 1

Use one 6” section of rubber sealing tape. Starting at the TR850 end, stretch the tape and wrap it around the

connector as close as possible to the wall of the TR850. Overlap the tape by approximately one-half of it’s

width so that it can form a seal with itself. Extend the wrapping to approximately one inch past the end of the

connector.

STEP 2

Cover the sealing tape with electrical tape (not provided). Start approximately one inch further down the

cable, and stretch the tape, overlapping by one-half. Wrap to the TR850 end and without breaking the tape,

wrap back down to the cable end.
