Also remote control does not work.However, the CLEAR operation is enabled.During Self-diagnostic, the power supply for amplifier circuit become low voltagestate(SEC1-LOW), and the speaker relay will be turned off. Then, MPU will check eachamplifier circuits Internally by entering the test signal (20 kHz,-20 dBFS sine wave) toeach channel from DSP.MPU will judge the amplifier circuit is good or not from VOLH value.The normal range of VOLH value is 0.04 V VOLH 0.20 V.If VOLH value is in the out of this range, it will be judged as NG (No good).No problem foundWhen protected by current detection, and no problem found, CHECK SP WIRE“ will be displayed.In this State, Only the On/Standby key is effective. And if do not anything for 3 minutes, unit goesinto standby automatically.When protected by a DC voltage detection, and no problem found, unit goes into normaloperation.Problem foundWhen judged as there is a problem on any channel, the information of channel that has a problemwill be displayed as in the right figure.In this State, Only the On/Standby key is effective. Also remote control does not work. If do notanything for 3 minutes, unit goes into standby automatically.

Back Ground: It is totally different from Radio Law at the each country on 5GHz band. It means it is totally different from enabled Channel of 5GHz band at the each country. We define the “Country Code” for 5GHz band. You must set up the appropriate country code to the product. Example; Case1: When you use the “P” destination products and bring move to Russia or Israel, If you did not setup change country code and use in Russia and Israel, You will be on the illegal Radio Law in Russia and Israel. Case2; When you use “C” or “D” destination product bring move to Japan or Taiwan, If you did not setup change country code and use in Japan and Taiwan, You will be on the illegal Radio Law in Japan and Taiwan. Service Parts information: The default country code is set on “Processing Circuit Board(PRC board)”. You must make sure and set up the “Country Code“ when you replace the processing circuit pc board ( i.e. BAPRC-2034 ). Otherwise You and your customer should be on the illegal Radio Law and IT HAS POSSIBILITY TO HAVE A RISK OF PUNISHMENT FROM EACH COUNTRY GOVERNMENT. If you did not make sure country code and no setup code and face any trouble, We does not have any responsibility. For setting up the Country Code, Please ask the procedure of changing country code to your distributer or our sales. It is no described the procedure of changing Country Code on this Service Manual If you have any trouble of unclear procedure for update country code, Please contact our sales department. PRC Board Default Value of Country Code The PRC board is already set default Country Code by the representative destination. To confirm the default country code, Please refer to the How to read PRC Board part number and Default value of Country Code section.

Make sure and Setup Country Code You have to make sure country code for using or replacing “Processing Circuit PC Board”. It means that you have to make sure country code between using Processing Circuit PC board( PRC Board) and your customers country code. When it is not match PRC board default country code and customers country, you have to setup Country Code. Case3; When you repair the “P” destination products and replace “P” destination PRC Board and the customer live in UK, It is no necessary to setup Country Code Because “P” destination PRC board already setup “EU” country code. Match Country code NO NECESSARY TO SETUP COUNTRY CODE Case4; When you repair the “P” destination products and replace “P” destination PRC board and the customer live in Russia, It is necessary to setup Country Code Because “P” destination PRC Board already setup “EU” country code. However, the customers country code is “RU”. It means no match PRC Board code and Customers code. No Match Country code NECESSARY TO SETUP COUNTRY CODE Case5; When you repair the “C” destination products and replace “C” destination PRC board and the customer live in US, it is no necessary to setup Country Code Because “C” destination PRC board already setup “US” country code. Match Country code NO NECESSARY TO SETUP COUNTRY CODE Case6; When you repair the “C” destination product and replace “C” destination PRC board and the customer live in Taiwan, It is necessary to setup Country Code. Because “C” destination PRC Board already setup “US” country code as default. However, the customers country code is “TW”.
