3D-MC: Satel radio guide for MC

The indicator on the upper left corner has two functions:

• Antenna symbol followed by Received Signal Strength  (RSSI) in dBm units. RSSI will be shown for about 7  seconds after the last message has been received.
• “n” symbol followed by the noise level whenever RSSI is not shown i.e. there are no messages from any other compatible radio modem detected.

The two lines in the middle revolve automatically every 5 seconds displaying the basic settings, as illustrated

There are two options to proceed from the top level view:

1. Press INFO button to view the info pages
