Version Display ModeFor this mode it displays the version num on NIXIE tube, like [.5. 1.00.] means currentsoftware version is 1.00;Long click the [SET] button to enter the setting mode:[.5.1.XXXX] IR Test Mode; It will display the decoded value of infrared codes; Canbe used to determine weather the infrared remote control is working properly;[Reset All]: Set this number to [01], then click the [set] button, all the settingswill be reset to the default, and the clock will reboot itself when finished.About the noiseWe use the PWM signal to adjust the NIXIE tubes' brightness; some tubes do sound whenyou set to the lower brightness levels because of the segments inside the NIXIE tubeseems not installed very tightly. We can't change the tubes structure but we willtry our best to reduce this noise by changing the PWM frequency.Tips: When you set the clock to the highest brightness level (level:8),you can stopthe noise immediately, because in this level, it does not use the PWM signal.
