Maintenance Features:

Connecting to Your Computer: The HL77 can be connected to a Mac or Windows computer via a mini USB cable to backup or load phrases (as WAV files). The pedal will display "U 5" when successfully connected.
- Importing WAV Files: Open the HL77 Removable Disk, then the HARTKE folder. The WAV folder contains 99 folders for the 99 memory locations. To load a sample, select a memory number (e.g., W002), rename the WAV file to w002.wav, and drag it into the folder.
- Backing up files: Copy the entire HARTKE folder from the HL77 to your computer.
- Overwrite/Recover backed up data: Delete all folders within the HL77 root directory. Copy the HARTKE folder from your computer to the HL77 root directory.
- Important Notes for Computer Connection: The HL77 will not operate on USB power. The SAVE/DELETE button flashes when data is being transferred. Do not turn off the power or disconnect the cable during data processing. Do not delete folders inside the HL77 drive unless you are overwriting or recovering data. Do not place more than one WAV file in any folder. When naming files, use uppercase and lowercase characters (A-Z, a-z), numbers (0-9), or underscore (_).
Powering the HL77: When running on battery power, connect an instrument cable into the OUT L jack to automatically switch the power on. To prevent damage, always turn down the volume and turn off all devices before making any connections.
Installing a Battery: Install a standard 9-volt battery by removing the battery door and attaching the battery to the terminal connector. Fit the battery into the compartment and reinstall the battery door.
Using an AC/DC Power Adapter: Use an adapter to power the HL77. Plug the power adapter into the DC inlet and then plug the power adapter into a standard AC power outlet.
Self-Test: The HL77 will take a few seconds to run a self-test and display "SC" when powering on. Once completed, the HL77 will be ready to operate.
