The power consumption for the sleep mode position reporting
and SCADA reporting application can be estimated by the fol-
lowing values:
Receive power is approx. 3.8W, transmit power is 80W, the GPS
module consumes 0.6W, and the typical report requires about
300ms of transmit time.
This yields the following estimates for the average power con-
sumption for a complete transceiver, when operating in this
mode:

Front indicators and buttons
The functions of the five indicators, the Stop and Alarm buttons
are as follows.
The
Power indicator
will always be on when there is DC-power
on the Transceiver.
The
Stop button
is used to set the serial port to the default values.
If this button is pressed at power-on the serial port is set to 4800
baud, 8 databits, no parity, 1 stopbit. If the button is pressed after
the Transceiver is turned on, nothing will happen. The
Stop but-
ton
can also be used for switching off the
Distress indicator
when the distress acknowledge has been received. Finally the
Stop button
can be used for initiating a manual positioning report
if the transceiver is configured for this operation.
The
Login indicator
will be on when the Transceiver is logged
into an ocean area. If the Transceiver is in synchronisation but
