Sec.  80.1095   Survival craft equipment.

   (a) At least three two-way VHF radiotelephone apparatus must be provided on
   every passenger ship and on every cargo ship of 500 tons gross tonnage and
   upwards. At least two two-way VHF radiotelephone apparatus must be provided
   on every cargo ship of between 300–500 tons gross tonnage. Portable two-way
   VHF  radiotelephones must be stowed in such locations that they can be
   rapidly  placed in any survival craft other than liferafts required by
   Regulation III/26.1.4 of the SOLAS Convention. Alternatively, survival craft
   may be fitted with a fixed two-way VHF radiotelephone installation. Two-way
   VHF radiotelephone apparatus, portable or fixed, must conform to performance
   standards as specified in  Sec. 80.1101. Two-way VHF radiotelephone apparatus
   provided on board ships prior to February 1, 1992, and not complying fully
   with the performance standards specified in  Sec. 80.1101, may be used until
   February  1, 1999, provided it is compatible with approved two-way VHF
   radiotelephone apparatus.

   (b) At least one radar transponder must be carried on each side of every
   passenger ship and every cargo ship of 500 tons gross tonnage and upwards.
   At least one radar transponder must be carried on every cargo ship of 300
   tons gross tonnage and upwards but less than 500 tons gross tonnage. Such
   radar transponders must conform to performance standards as specified in
    Sec. 80.1101. The radar transponders must be stowed in such locations that they
   can be rapidly placed in any survival craft other than liferafts required on
   cargo ships in forward and aft areas (see Regulation III/26.1.4 of the SOLAS
   Convention). Alternatively, one radar transponder must be stowed in each
   survival craft other than those required by Regulation III/26.1.4 of the
   SOLAS Convention. One of these radar transponders may be radar transponder
   required by  Sec. 80.1085(a)(3).

   (c) Survival craft equipment must be tested at intervals not to exceed
   twelve months. For batteries used for survival craft equipment, the month
   and year of its manufacture must be permanently marked on the battery. Also,
   the month and year upon which 50 percent of its useful life will expire must
   be  permanently  marked  on  both  the  battery and the outside of the
   transmitter. Batteries must be replaced if 50 percent of their useful life
   has expired or if the transmitter has been used in an emergency situation.
