Lost Communications

Once communication starts with a Sender the display keeps track of it. In case you get out of range, forgot to charge the battery, or any other reason it quits hearing the Sender, it will switch to a LOST COMM display so you know you aren't getting real time pressure readings anymore. If it was momentary interference it will switch back to real time view as soon as it hears from the Sender again.

Diagnostics

The diagnostic screen will show the firmware version, light level reading and data for each Sender's radio signal strength (SNR & RSSI) and packet count received. You can access the diagnostics screen by center pressing the joystick.

If the screen backlight is not functioning automatically, check to see if the light sensor is showing different levels by covering it with a finger. The light sensor is located directly above the joystick. You may have the backlight turned on or off. Use the menu to verify the backlight display setting.

If you aren't receiving readings on the display, check to see if packets are being received. You may have different range or group ID settings on the Sender and display. Use the menu to verify they are set the same.

SNR and RSSI explained:

Signal Noise Ratio (SNR): ratio between the received power signal and the surrounding signal sources. Values range from -10 to +13. Below 0 some packets will be missed possibly resulting in temporary LOST COMM displays.

Received Signal Strength Indicator (RSSI): is a measurement of how well your device can hear a signal. Values range from -20 to -130, -50 to -90 is very good. At values from -120 to -130 some packets will be missed possibly resulting in temporary LOST COMM displays.
