capacity to ensure at least 8 hour operation at the highest rated power of the
equipment with a duty cycle of 1:9. This duty cycle is defined as 6 seconds
transmission, 6 seconds reception above squelch opening level and 48
seconds below squelch opening level. The source of energy should comply
with one of the following:
(a) A sealed primary battery which should be of a type which will not emit
substances which may be injurious to personnel, or damaging to the
equipment or fabric of the survival craft. This requirement should be met
whether the power source is in a stored condition or normal use. The battery
should be clearly marked with the shelf life whose expiry should not be less
than 2 years from the date of survey. The battery should have sufficient
capacity so that routine testing of 2 minutes once per week should not reduce
its capacity below that needed to conform to the operational requirements
recommended above.
OR
(b) A re-chargeable battery which should not emit substances which may
in any way be injurious to personnel, or damaging to the equipment or fabric
of a survival craft. This requirement should be met whether the power source
is in a stored condition or in normal use. Batteries that have been in service
for more than two years should not be used for this purpose. The battery
should be capable of fulfilling the capacity requirements recommended above
at all times. A means of automatically charging such batteries should be
provided which should be capable of recharging them to minimum capacity
requirements within 10 hours from the ship’s main source of electrical power.
Equipment for which the source or energy is intended to be user-
replaceable should be provided with a dedicated primary battery for use in the
event of a distress situation. This battery should be equipped with a non-
replaceable seal to indicate that it has not been used.
Equipment for which the source or energy is intended to be non-user-
replaceable should be provided with a primary battery. The portable two-way
radiotelephone equipment should be fitted with a non-replaceable seal to
indicate that it has not been used.
Primary batteries should have a shelf life of at least 2 years, and if
identified to be user replaceable should be either or a highly visible
yellow/orange colour or marked with a surrounding yellow/orange marking
strip.
Batteries not intended for use in the event of a distress should be of a
colour or marking such that they cannot be confused with batteries intended
for such use.
Batteries should be disposed of strictly in accordance with manufacturer’s
instructions.
