**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.

<WRAP round alert>
=== CAUTION ===
Before installing the UniCMT in place of the built-in cassette recorder, read these instructions carefully and make sure the computer is turned off and unplugged from the power.
Please, pay special attention to the connecting cable. Twisting the cable or wiring it incorrectly (e.g. moving it one pin too far) can damage the UniCMT and the computer!!!

**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.

**1st (left) LED**\\
The left LED indicates the status of the USB flash drive:
  * <color red>**red**</color> – USB flash drive is not inserted or does not have a FAT32 file system
  * <color green>**green**</color> – USB flash drive with a recognized file system is inserted

**2nd (right) LED**\\
The right LED indicates the status of the cassette recorder emulation:
  * <color gray>**not lit**</color> – nothing is happening, no more data, the manager will be loaded
  * <color green>**green**</color> – there are more data (multi file MZT), the engine signal starts playing
  * <color red>**red**</color> – playback finished, nothing is sent until the motor signal
  * <color orange>**flashing orange**</color> – loading from emulated cassette recorder
  * <color red>**flashing red**</color> – saving to emulated cassette recorder

**Grey (left) button**\\
It has no function in the current firmware and is only used for updating it, see below in the section **Firmware update**.

**Red (right) button**\\
It has no function in the current firmware except reset after firmware update. When SW1 is ON, it is used to reset the internal MPU. This can be used in case you want to e.g. exclude files from the playback queue and do not want to reset the whole computer.

**DIP switch**
It is used to preset some hardware functions. In the current firmware only SW4 is relevant, or SW1 can be used (hardware connected).
  * **SW1** – in the **ON** position the red button is connected to **reset the MPU**
  * **SW2** – it has no function in the current firmware
  * **SW3** – it has no function in the current firmware
  * **SW4** – in **ON** position the manager boot is adapted **for MZ-700**

<WRAP round tip>
**SW4 setting to ON is necessary for MZ-700 EN and JP computers**\\
the name when loading the manager contains unreadable characters\\
this is fine, it's machine code to speed up the loading process
