LabSat 4 is shipped with a rechargeable, lithium-ion smart battery pack. A fully charged battery provides a unit operation time of a minimum of 1 hour. You can charge the battery by connecting an external power source to the Power port on LabSat 4. 

You can read more about the battery pack, including operation, charging, fitting, removal and handling, here.

You can apply power to LabSat 4 via mains power with the power supply (RLVBACS020) or from the vehicle via the cigar plug to power (RLCAB010LE) cable. When you power LabSat 4 from an external source, it will automatically charge the internal battery pack, and seamlessly switch to battery operation when the external power is removed.

This is an example of how to record a file to the internal SSD on LabSat 4.

Additional Info

During recording, if the SSD becomes full, the recording will stop automatically. 

LabSat 4 contains an onboard GNSS receiver that gives you the ability to monitor the RF signals during record or replay. If you press the OK button while the unit is recording, it will switch the display to show available satellite levels for the different constellations. In this display mode, you can use the UP/DOWN buttons to toggle between the different constellations. Press the OK button in this display mode to open the file status. Press the OK button again to return to the record status display mode.
