./ ! "%) 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 TR700B.
STEP 3 When done, the connection should be tightly wrapped with tape, with a good seal to the cable. DIAGRAM 2.5C: WATERPROOFING CONNECTION – STEP 3 VCom Inc. TR700B Manual; ml_tr700B_02 (March 2004) Approved: C.H.
