Appendix C SAT Radio Diagnostics

Enter Engineering Mode on the RNS-E (see Appendix B). Use the control knob to select the

Audio/Tuner button and then select the SDARS testmenu. This screen is full of values that describe

the operation of the SAT tuner. SAT1, SAT2, and TERR are the “addresses” of the signals it is

receiving. SAT1BER, SAT2BER, and TERRBER are the B

it Error Rate of the signals it is receiving. This

number is a HEX value that represents a percentage of bits that are received in error. Therefore, a

“0000” means that it has zero percent error, or perfect signal. If it has a “270A” for any BER value

(equals 99.99% error) that means it is not receiving any signal from that source. The SAT1 or SAT2

BER should be under 3% (012C) and the TERRBER should be under 6% (0258) to ensure a good

listening experience. On the RNS these four digit hex values are listed out of order. For an actual

value of “1234”, the digits are listed in the order “3412”. By this logic, the display of “0A27” translates to

“270A” which means “no signal” as described earlier. To exit engineering mode press the return button

a few times until the unit is back to the regular navigation screen.
