Wuxi Weida Intelligent Electronics Co., Ltd.

2 Remote control instructions 1. Basic requirements for remote control
1). 1). When Bluetooth is connected, the remote control sends the Bluetooth key value; when Bluetooth is not connected, the infrared key value is sent.

2). BT BT IR
2).Indicator light: When working with BT, the button flashes blue light; when not connected to BT, when working with IR, the button flashes red light. Each time the button is pressed, the indicator light flashes

3). 2.4v±0.05v LED 3 2.0V 3). Low voltage reminder: When the power is lower than 2.4v±0.05v, press the button and the red LED flashes 3 times to indicate that the battery power is insufficient and the battery needs to be replaced in time.When the voltage is lower than 2.0V, the remote control does not work.

4). a. HOME+BACK 3 3 b. HOME+BACK c. HOME+BACK
d. Connection interval12ms 4). Pairing method:
a. Press and hold the HOME+BACK keys at the same time for 3 seconds, the indicator light flashes, and the pairing success indicator light is always on for 3 seconds and then goes out. b. When the pairing is not successful, if you still press the HOME+BACK key, you must keep sending the pairing broadcast so that the user can pair. c. Press the HOME+BACK button once to be able to pair successfully, do not clear the pairing repeatedly and then pair. After a key pairing is successful, the pairing broadcast can no longer be sent until the key is pressed again next time. d. Connection interval12ms

5).10m 5). Remote control distance: 10m

6). RemoteB064 6). Bluetooth device name: RemoteB064

7).”OK+Back” 7). Bug report : Press the “OK+Back” keys together support upload bug report .

8). 5.0 8). Support to connect to devices with Bluetooth version 5.0

2. Remote control other requirements 1). 50 1). Pairing function requirements: there must be no problems that the Bluetooth device cannot be scanned or paired (including continuous pressing of the pairing key within a short period of time), please verify 50 times to ensure that there is no problem;
2). : 2 50 2). Reconnection function requirements: there must be no problems with the connection failure, including the box power failure and the connection, the remote control power failure and the connection, stand for 2 hours to reconnect, etc., please verify 50 times to ensure that there is no problem; 3). WIFI WIFI 3). Anti-interference function requirements: there must be no problems that greatly affect the host’s WIFI throughput, please ensure that the host’s WIFI throughput is normal when connecting the remote control;
4).10m 4). Performance requirements: It is required to support 10m, and there must be no voice call jams, loss, and remote control button jams, missing codes, or continuous keys;
5). 6 5). Power consumption requirements: the remote control can be used continuously for at least 6 months

6). 16Khz voice sample with 16-bit sampling

30s

6). Voice: 16Khz voice sample with 16-bit sampling, short press the voice button (color button) to start

recording, and the remote control will stop recording after receiving the stop recording command from

the voice engine. The voice timeout is protected for 30s, and the recording is forced to exit.

7). MIC 7). The box software can control the opening and closing of the MIC.

8). MIC MIC apk 8). Support the remote control MIC and other MIC (such as the recording key on the phone apk) to alternate and switch voice input.

9)THD 5%@1KHz 200Hz 8KHz +/-5dB 94dB SPL 1KHz 9) Other requirements: Harmonics (THD) must be less than 5%@1KHz; amplitude +/-5dB in the frequency range of 200Hz to 8KHz; 94dB SPL reference sound pressure level 1KHz.
