4.0 STATUS LEDS
The 9602-AB has five status LEDs as shown in Figure 1. These include power indicator, GPS availability,
Iridium signal strength, SBD transmission status and Emergency mode alert. They offer users a quick visual
check to ensure proper operations. These LEDs provide the following information:
Power LED:
o
Solid: when battery level is at +80% or when battery is fully charged with power cable
plugged in.
o
Rapid blinking (on 0.5 second, off 0.125 second): when battery level is between 50% –
80% or when battery level is between 50% – 90% with power cable is plugged in.
o
Slower blinking (on 1 second, off 0.25 second): when battery level is between 20% – 50%.
o
Slow blinking (on 2 seconds, off 0.5 second): when battery level is between 0% – 20%.
o
Very slow blinking (on 0.1 seconds, off 5 seconds): sleeping between reports.
o
Off: when the device is off.
GPS LED:
o
Solid: when there is a valid 3-D position fix.
o
Blinking: when there is 2D position fix.
o
Off: when unable to obtain a position fix or only able to obtain time or GPS receiver is off.
Iridium LED:
o
Solid: when the Iridium signal strength is between 3–5 bars.
o
Blinking: when the Iridium signal strength is between 1–2 bars.
o
Off: when the Iridium signal strength is at 0 bar or Iridium transceiver is off.
Status LED:
o
Solid: when the most recent SBD transmission succeeded.
o
Blinking: when an SBD transmission was successful in the past, but the most recent
transmission failed.
o
Off: no successful SBD transmission yet.
Emergency LED:
o
Solid: when emergency is enabled.
o
Off: when emergency is disabled.
5.0 POWER CONSUMPTION
The 9602-AB has an internal 1.95 A-Hr Li-Ion rechargeable battery. When both the Iridium and GPS
antennas have clear view of the sky and the battery is fully charged, the 9602-AB is capable of sending
more than 1,500 tracking reports with report rate set to less than two hours. Blocked or partially blocked
antennas will force the 9602-AB to retry multiple SBD transmissions for each report and, as a result, can
significantly reduce the overall number of reporting cycles.
