This screen displays the received signal strength in dBm. The reading is typically accurate

within +/- 2 dBm between -120 and -80dBm, when the radio has been correctly calibrated.

For example, -90dBm is a strong signal and –120dBm is no signal.

The screen also shows the Bit Error Rate (BER) on digital channels. RSSI and BER are

typically used to indicate signal quality.

From the Settings Sub Menu, step through the menu options with the ▼ and ▲ keys until the

“RSSI” menu is displayed.
