d. A cable which is enclosed in shielding conduit for only part of its entire length (partial
shielding) shall be identified with tags mounted on both the exposed (unshielded)
portion of the cable and on the conduit at the locations described in paragraph b above.
e. Cables serving a dual purpose (transmitting and receiving) shall be identified with both
radiator and susceptor designators as shown in example 4 below.
f. A multifunction cable carrying signals that fall in radiator and susceptor categories shall
be classified as both a radiator and a susceptor using the cable designator from figure
6-6 requiring the greatest cable spacing. This cable will be identified with both radiator
and susceptor designators as shown in example 4.
g. A multifunction cable carrying signals that fall in more than one radiator category or in
more than one susceptor category, shall be classified and marked with only the radiator
or susceptor cable designator from figure 6-6 requiring the greatest cable spacing.
h. Special case cables shall be identified by adding "S" to the cable designator as shown
in examples 5 and 6.
The following are examples of cable identification tag information.

The following EMC cableway caution tag is designed to be attached to cableways containing
susceptor cables to remind ship and shipyard personnel not to inadvertently violate EMC cable
spacing. This tag shall be attached with tie-wraps to the exterior of cableway supports or pans in
visible locations approximately every 5 feet along the cableway. The preferred material for this tag is
metal or nylon colored blue. The tag shall be embossed with raised letters. The letter size for the
words "CAUTION" and "EMC CABLEWAY" shall be approximately 3/16 of an inch high, and the
remainder of the text shall be approximately 1/8 of an inch high.
