1. Turn on the MR265 switch and select the RX mode. When the power button is long for 2 seconds and the LOGO backlight is on, the MR265 enters the backconnection mode and automatically connects back to the last connected device. (When the device is powered on for the first time or factory Settings are restored, the device directly enters the pairing state.) If you need to connect a new device, press and hold the play\/Pause button for 3 seconds to enter the pairing state, and the blue light of the Bluetooth indicator on the left side blinks quickly (blinks once every 0.5 seconds, and enters the waiting state after 30 seconds of no connection).<\/p>\n

2. Enable the Bluetooth of the paired device.<\/p>\n

3. Search for connected devices on your Bluetooth device, find MR265 and tap Connect with it. If the pair is successful, the blue light of the Bluetooth indicator is on.<\/p>\n

4. With or without a paired device, the MR265 can enter forced pairing mode and connect to another device by holding down the play\/Pause button for 3 seconds. In pairing mode, the blue light of the Bluetooth indicator blinks quickly.<\/p>\n

5, the Bluetooth device is disconnected from MR265, the first 5 minutes MR265 is in the automatic connection state, the Bluetooth indicator flashes twice in 4 seconds, after 10 minutes into the standby state, the Bluetooth indicator flashes once in 4 seconds, disconnect the link for more than 30 minutes, no charging current input, MR265 will automatically shut down.<\/p>\n

Unpaired: Deletes all connected Bluetooth device records from your phone or tablet device. Restart the phone or tablet to restore the Bluetooth driver of the device and reconnect the device.<\/p>\n

1. Turn on the MR265 switch and select TX mode. When the power button is long for 2 seconds and the LOGO backlight is on, the MR265 enters the backconnection mode and automatically connects back to the last connected device. (After the first boot or factory Settings are restored, the boot directly enters the pairing state)<\/p>\n

2. If you need to connect a new device, enter the Bluetooth pairing state of the Bluetooth device (Bluetooth speaker or headset) to be paired (blue light blinks quickly or red and blue light blinks alternately, see the device description for more information).<\/p>\n

3. Press the Power button or + button to enter the pairing state. The blue light of the Bluetooth indicator blinks quickly (once every 0.5 seconds), and the matching state is automatically entered. 30 seconds No connection Enters the waiting state.<\/p>\n

4. After successful pairing, the MR265 Bluetooth status and protocol indicator will be steady on (SBC\/aptx\/ APTX-LL\/APTX-HD). According to the peer-to-peer protocol principle, the MR265 will automatically adjust the protocol and display the blue light according to the protocol of the matching Bluetooth device.<\/p>\n

5. To match the second device, repeat steps 2), 3).<\/p>\n

4, Back connection and transmission distance<\/strong><\/p>\n

1, when the Bluetooth device and MR265 have been successfully paired, when the Bluetooth device is turned on again, it will automatically connect back to MR265;<\/p>\n

2, when the Bluetooth device has been turned on and is waiting for the connection state, the MR265 will be automatically connected to the Bluetooth device when it is turned on;<\/p>\n

3, MR265 normal effective connection distance up to 30M (depending on environmental interference will be different);<\/p>\n

4, because the aptX-HD protocol wireless transmission of 24-bit audio, the amount of data is much larger than the ordinary 16-bit audio, higher requirements for the environment. Please use at the effective distance, the overdistance will be stuck immediately. Place the device close to or disable the aptX-HD protocol of the MR265.<\/p>\n

5, charging and power saving<\/strong><\/p>\n

1. Charging<\/p>\n

 <\/p>\n

\"MR265\u9ad8\u6e05\u84dd\u7259\u53d1\u5c04\u63a5\u6536\u4e8c\u5408\u4e00\"<\/p>\n

When the amount is too low, the brand LOGO backlight flashes. Please charge the MR265 with the included USB charging cable.<\/p>\n

It is recommended to choose a 5V 1A charger with an output voltage (be sure not to use a variable voltage fast charge).<\/p>\n

When charging, the LED charging indicator light is steady red, and the red light is turned off after it is full. A full charge takes about 2 hours, as the charging current varies.<\/p>\n

Note: When charging the MR265 with the USB charging cable, the MR265 will turn on automatically. MR265 unconnected Bluetooth devices will not enter automatic shutdown.<\/p>\n

2. Save electricity<\/p>\n

When the MR265 is not charged in standby state and there is no Bluetooth device to connect to, it will automatically shut down after 30 minutes.<\/p>\n

About compatibility issues<\/p>\n

When using CSR chip, the compatibility is the best. If your two Bluetooth devices use different Bluetooth schemes, because of different chip designs, the three different brands of chip devices may not be synchronized or connected, which is caused by different differential emission schemes used by the devices. You can try to replace two Bluetooth headsets of the same brand, preferably one with a CSR chip.<\/p>\n

Eight, common problems and solutions<\/p>\n

Can not boot<\/strong><\/p>\n

\u2022 Select a qualified adapter to power on, it is recommended to choose an output voltage of 5V 1A adapter (be sure not to use a variable voltage fast charge).<\/p>\n

\u2022 Turn on the switch.<\/p>\n

\u2022 Check whether the power cable is normal.<\/p>\n

unpairing<\/strong><\/p>\n

\u2022 Ensure that the product is in the corresponding pairing mode (RX-receive, TX-transmit) and the indicator light is blinking.<\/p>\n

\u2022 Ensure that the product is within range of the pairing device (first close to the connection).<\/p>\n

\u2022 Delete all connected Bluetooth device records from the phone or tablet device, restart the phone or tablet to restore the device’s Bluetooth driver, and reconnect the device.<\/p>\n

\u2022 When the distance is too short or the connection is not successful, please check whether there is too much interference from 2.4G wireless devices around the environment (such as WiFi signal, wireless mouse, other Bluetooth devices, etc.).<\/p>\n

About current noise<\/strong><\/p>\n

1. Please check whether the audio cable is improperly connected and re-plug the rotary audio cable connector;<\/p>\n

2. If the power cable and audio cable are connected to the same device, please connect the power cable to the main charge or replace the power supply to avoid interference from the common ground power supply.<\/p>\n

3, due to the weak anti-interference ability of some audio source equipment, other wireless signals are imported into the audio source along the audio line, causing interference. Please change the audio cable with shielding or use another device to test.<\/p>\n

4, some audio sources informal standard transfer, please replace the audio source test.<\/p>\n

Does not match with computer Bluetooth<\/p>\n

\u2022 Download the latest driver from the Bluetooth manufacturer or download Chizuki software (supports A2DP protocol). Contact your PC supplier for more information.<\/p>\n

\u2022 Or download third-party Bluetooth driver: Chiki software (supports A2DP protocol).<\/p>\n

The device can’t hear the sound<\/strong><\/p>\n

\u2022 Ensure that the device is properly connected to the product and the input mode is correctly set<\/p>\n

Receive mode (RX) – Corresponds to OUTPUT output port<\/p>\n

Transmit mode (RX) – corresponds to the INPUT signal input port<\/p>\n

\u2022 Check the volume of each connected device<\/p>\n

\u2022 Ensure that the sound of audio source devices such as TVS is set to fiber or coaxial output and that the audio format is PCM.<\/p>\n

\u2022 Ensure access to the corresponding digital or analog input\/output mode. \u2022 If the digital audio transmission synchronization with the connected device is abnormal, please press the reset button in the AUX hole to reset and restart.<\/p>\n","protected":false},"excerpt":{"rendered":"
