Power Supply
Battery
LabSat 4 (RP) is shipped with a rechargeable, lithium-ion smart battery pack. A fully charged battery provides a unit operation time of minimum 1 hour. You can charge the battery by connecting an external power source to the Power port on the LabSat 4 unit.
|
Notes:
- For safety reasons, the battery will not be fully charged when shipped from us. We recommend that you charge it fully before use or connect the LabSat 4 unit to external power the first time you use it.
- Take note of the expected operation time and make sure that you have access to an external power source (and the appropriate cable for it) if you think it will take more than 1 hour.
|
|
WARNING
- Never leave a system unattended during the charging or discharging of the battery pack.
- The battery should be fully charged when stored.
If a battery is left depleted for a prolonged period then it is likely that the performance of the battery will degrade and may be unusable.

External Power
You can apply power to LabSat 4 (RP) 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.
Recording
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.
| Note: During recording, while using battery power, the GNSS monitor display will automatically revert to the record display after a short period to conserve battery power. This power save feature can be switched off, but it is recommended to be left active for maximum battery life. |
Replaying

Additional Info
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 replaying, 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 replay status display mode.
|
Note: When you switch between GNSS monitor modes, it will take some time for the internal receiver to re-acquire satellite signal levels.
