H2 operation

Inserting a USB drive or AUX source can interrupt Bluetooth. The last mode is remembered after power loss, and Bluetooth is not discoverable in USB or AUX mode. The blue indicator flashes slowly in USB/AUX mode, stays on when Bluetooth is connected and flashes very slowly without a connection. For TWS pairing, the red light flashes while searching, stays on for the left channel and flashes slowly for the right channel.

Check before connecting power

The supplier gives conflicting H2 voltage ranges: 8–36V DC for the upgraded model and 8–26V DC for the board-only package. Confirm your selected version’s label and documentation before connecting it. Never connect AC power. The board-only H2 lists a 10K single potentiometer with a 6mm splined shaft and 23.34mm spacing. Connect its audio output to a compatible power amplifier; this is not a complete speaker system.
