The BHT shall be reset if the program does not respond or run properly by touching the panel or the key. If this problem still remains, you need to full reset the BHT. Once the BHT is reset, the files and settings not yet saved in the RAM are cleared but those already saved are retained. In the case of full-reset, the programs and files saved in the RAM are all erased and all the settings are initialized. Therefore, you are recommended to back up the critical data in advance.
