2BDAL-RC-50Bluetooth voice remote control

The product name is Bluetooth voice remote control model name is RC-50 Product description: instructions device name：RC-50 While holding down the【back】and【home】buttons on the remote control for approximately 3 seconds, the working indicator light flashes, indicating that the pairing mode has been entered. Turn on the host's Bluetooth - click on the host's Bluetooth - search for devices - connect to the device named "RC-50" and complete the connection. During the Bluetooth pairing process, the indicator light flashes. If the pairing is successful, the light will remain on for 3 seconds; if the pairing fails after 60 seconds, the light will go out (after the pairing broadcast ends, it enters a low-power state). power alarm When the battery power is lower than 2.2V, Every time the user presses a key, Press any key, the red light flflashes for 3s, and the frequency is 1Hz Back connection When there is pairing information, press any key to send the corresponding infrared code. The reconnection is successful, and the indicator light remains on for 3 seconds (the reconnection broadcast time is less than 5 seconds, and it enters a low-power state after the reconnection broadcast ends). 4.Bluetooth unpairing Press the shortcut key on the remote control to deactivate the Bluetooth pairing. If the deactivation is successful, the indicator light will remain on for 3 seconds.. After the Bluetooth connection is established and the device is in standby mode, press the button that sends the Bluetooth code. The Bluetooth broadcast will be a directional broadcast and the TV will reconnect normally. (Bluetooth is not connected. Pressing any key cannot send non-directional broadcasting. Only the designated pairing key can send non-directional broadcasting.) After the Bluetooth connection, back+home disconnects the Bluetooth connection but does not clear the pairing information (a Bluetooth directional broadcast is sent after the Bluetooth is disconnected). 6. sleep and wake up Bluetooth sleep mode: The Bluetooth sleep time is ≥1 hour. When Bluetooth is in sleep mode, the function is normal: When operating the remote control in Bluetooth sleep mode, the first key press can normally respond to the infrared function, and the second key press can normally respond to the Bluetooth function. 7. OTA When the TV is turned on, the upgrade fifile of the remote controller is detected. If the upgrade fifile exists, the remote controller performs OTA upgrade, and the LED lamp flflashes. At this time, the remote controller can't be used, and any buttons don't respond. After the upgrade is successful, the LED light stops flflashing, and the remote controller can be used normally at this time. If the upgrade fails, it will be detected and upgraded again at the next boot. After OTA fails, the LED light stops flflashing, and the remote controller returns to the old version for normal operation. 8. PID/VID vendor:0x0B7A.product:1489 FCC Warnning: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 0cm between the radiator and your body.
