The method to enter H/U diagnostic mode is by press-&-hold the INFO button and preset M1 simultaneously for more than 3 seconds.

2. Diagnostic Messages
Use the CAT/FLDR up/down button to cycle through the various test messages provided by the SDAR.
The sequence of cycling is as followed: Tone Frequency -> Tone Level -> RTone LTone -> QOS Value -> TERR Status -> SAT1 Status -> SAT2 Status -> TUNER Status -> SDEC1 Status -> SDEC2 Status -> TERR Status -> SW ID -> AREA -> Tone Frequency.
The first three test tone menus allow viewing and changing on the test tone settings by turning the AUDIO CONTROL knob. For LTONE/RTONE on/off, every 1 click clockwise turning shall select a combination in the following sequence: OFF/OFF and ON/ON. Turning anti-clockwise shall reverse the sequence. For TONE LEVEL, every click shall increment or decrement the value by 1. And for TONE FREQUENCY, every click shall increment or decrement the value by 100Hz. Turn clockwise to increase and anti-clockwise to decrease the value. By default, the test tone is set to ON/ON with frequency set to 1000 Hz and level set to 0. SDEC1, SDEC2 and TERR Status means BER(Bit Error Rate) and CN(Carrier to Noise). SW ID means software version on the company of development. AREA means the broadcast country. (USA or CANADA)
