Test Satellite Reception

Before completing the final installation, you can ensure that the RM4210 or RM4211 have adequate satellite signal to communicate with the Bullhorn Web account using Bullhorn Tools (RM4210 only) or Bullhorn Tools Mobile (RM4211). If reception is minimal, the unit may not be able to send information to the website. The Radio SNR reading should be at least 40 dB for a stable communication link with the satellite. If this reading falls below 37 dB, contact AI Support for instructions.

You can also email AI Support by tapping in Bullhorn Tools Mobile, which will include unit information and a log file with your email.

  1. Activate the unit by swiping a magnet across the access point on the unit (marked with an arrow on the enclosure). A red light flashes to indicate that the unit is waiting to pair with your device. Once the unit has paired with your device, the light will stop flashing and remain on.
