Setup and Operation
Operation Method:
Power on the device using a mobile phone charger plug with an Android data cable (Micro USB). The frequency will default to 7.83Hz upon boot. To adjust the frequency, directly input the desired frequency via the keypad and press the “OK” button to confirm.
For example: To set the frequency to 888Hz, after powering on, input the digits [8][8][8] on the keypad and then press the [OK] button. The device will display "Loading..." and then the new frequency.

External Antenna Usage
To use an external antenna, insert one end of the AUX audio cable into any headphone jack on the main unit. Connect the other end to the headphone port on the external antenna board. Ensure the cable is fully inserted for proper operation.
The headphone ports support daisy-chain configuration, allowing multiple external antenna units to be used concurrently. Connect AUX audio cables to the corresponding headphone ports on each device to achieve multi-unit daisy-chain operation. A single main unit can accommodate up to 10 antenna boards.
