Limited Power Mode

In Power Limited mode, GPS/Iridium/GSM is turned off until the Early Wakeup time defined above. Devices are not pageable during this mode.


Unlimited Power / GPS HOT on Battery

  • Setting your device to "Power Unlimited" will deplete your battery faster.
  • Setting your device to "GPS Hot" will deplete your battery faster.

Unlimited Power Mode

In Power Unlimited mode, GPS/Iridium/GSM stay on permanently. Devices are pageable in this mode, and any messages and/or configuration reports are received by devices as soon as they become available.


GPS + Iridium SBD 'HOT'

In Unlimited Power mode (typically when connected to an external power source) a device will keep its GPS chip and Iridium modem HOT, i.e. powered, at all times. This enables it to maintain an accurate GPS fix more easily, and also means the device will receive messages from Iridium faster.

Unlimited + Activate

Unlimited+Activate mode automatically deactivates the device when external power is removed.


Unlimited + Activate

  • As a safety measure, the device will not be automatically deactivated unless the GPS speed remains lower than 10 knots or if no GPS fix can be established e.g. if the tracker is under a hanger roof for at least 1 minute.
  • Unlimited+Activate mode is available only in the RockAIR and RockFLEET

Auto Select Power Mode

Auto Select will use Unlimited power when external power is present or Limited power mode if it is not.
