T.007 5.d Battery Consumption Modes
From the analysis given below it can be seen that the worst case mode
that draws the maximum battery is for the EPIRB1 model with GNSS
receiver in the operational condition activated by the water contacts, with
the strobe on and with the GNSS receiver in search mode (no GPS signal
present).
During stowage the EPIRB1 will be fitted in its manual release bracket
which inhibits the water contacts. When released from the bracket the
EPIRB1 is in standby mode with the water contacts enabled. The
additional current the water contacts draw when enabled, but not
activated is included in the stand by mode figure given in line 1.
There are no other operating modes that draw peak currents higher than
during the highlighted mode (line 5).

Note: for the Australian and New Zealand markets, the EPIRB1 will be supplied as
Category 3 only. Category 3 is only allowed in these two markets and does not require
automatic water activation. Therefore this variant of the EPIRB1 will be built as hardware
number 900S-01528, omitting the water contacts. Because the water contacts are now
omitted, the maximum current draw will be as specified in line 3, which is less than the
maximum current draw specified for other variants.
