Cassette recorder connector
It is used to connect the UniCMT to the computer. The cable must be plugged in straight, not twisted when the UniCMT is in the computer and the USB flash drive is facing the user. Please look carefully at the pictures.

Battery holder
CR1220 battery holder (battery not included). The battery is only used to maintain the internal clock, which is used to set the file time when saving files. If the correct time when saving files is not important to you, it is not necessary to install the battery. The accuracy of the internal clock is not high, the error can be a few seconds per day, please adjust it regularly.

USB flash drive connector
Format the USB flash drive up to 32 GB to the FAT32 file system. The file manager is stored in the internal memory of the UniCMT and can be loaded even without the USB flash drive inserted. All other programs and data must be stored on the USB flash. There may also be run.cfg file in the /unicmt folder on the disk with a configuration for automatically loading or running certain data types.
