Outside view

Operation buttons, USB TYPE-C, 3.5mm JACK, baseboard, battery, etc. are all concentrated in the left shell. The right enclosure is for speakers only.

Operation method

Turn on/off the power

• Perform this by operating the slide switch.

Join

• The Connect button must be pressed each time.

Volume UP Volume DOWN

• Press and press the volume + button continuously to operate. By short press, continuously press the volume-press to operate button.

charging

• Connect the USB cable to the USB Type-C port. When USB power is provided to the USB terminal, the system will automatically shut down even if the host power slide switch is in the ON position.

3.5 mm Jack

• After the 3.5 mm Plug is inserted, the power supply automatically turns off. Switch the speaker signal to a 3.5mm Plug signal.

LED display

• The power notification LED (green/orange) and charge notification LED (red) are built into the LED display window.

Indicator light (Green/orange) When the power is turned on, when the battery voltage is greater than or equal to 3.5V, the LED indicator (green) flashes; When the battery voltage is less than or equal to 3.5V, the LED indicator (orange) flashes Indicates the connection waiting state. Press the Connect button and switch to light after a connection is established. During use, when the battery voltage drops below 3.5V, the indicator light (green) goes off and the indicator light (orange) goes on. When the battery voltage becomes 3.3V, the power is automatically turned off and the LED is extinguished. In the case of automatic power OFF, sometimes even the ON/OFF slide switch operating the power supply can not be connected to the power supply, at this time by charging recovery.

LED indicator (red Colour)

Start charging by connecting the USB power supply to the USB TYPE-C port, and the red indicator lights up. When the battery is fully charged, the charge automatically ends and the LED (red) goes out. When the ambient temperature exceeds the rechargeable temperature range, the LED (red) goes out and the charging current does not flow. When the ambient temperature reaches the rechargeable temperature range, light up again. The charge can be charged in the range of 0 degrees ±3 to 45 degrees ±3. At other temperatures, charging stops automatically.

VOLUME Number of steps

• 10 VOLUME Settings. The GAIN value in each step can be changed in a step of 1dB. (Provisional values are as follows)

Beep Tone

• Inside the MCU is a PIANO TONE Generator that resembles a MIDI sound source.
• Chord number: 6, octave: C2~B6, rhythm: 1/4~4note, playback rate 60~120 beats/minute.
• Can be used for low-battery alarms, pairing tones and more. (If your company provides musical notes, you can use a PIANO TONE Generator))

3.5 mm Plug is supported

• Support 3.5mm stereo 3-pole mini plug. 4-pole plugs are not supported.

Check content during manufacturing

1. Confirm the internal voltage and current consumption
2. RF frequency calibration
3. RF TX POWER measurement RF RX receiving sensitivity measurement, AUDIO SIGNAL SNR/THD/LR LEVEL measurement
4. LED light, switch action, button action confirmation
5. charging action, charging current confirmation
6. 3.5mm JACK input confirm, JACK insert automatic OFF confirm, left and right cable confirm
7. sound phase, sound pressure, F characteristics, left and right sound pressure difference confirmation
8. Confirmation of RF output POWER inside the radio obscura (actual operation of the antenna)
9. Appearance inspection

Wireless stability
Since it is wireless communication, it is inevitable that communication will be interrupted due to interference. In addition, the 2.4GHz band is used by devices as diverse as microwave ovens, Wi-Fi, Bluetooth, codeless phones, and more. In the event of interference, only keep your distance from those devices.
