Wireless Keyboard Guide Keyboard Overview Other Fn combination keys Indicator lights: Product Specification Mode switching Bluetooth mode: Set the two gear switch to "ON" FCC Caution: Company Name: HAINAN JIAMEIHUACHENG INFORMATION TECHNOLOGY CO., LTD Made in China High end and dazzling backlit mechanical keyboard. RGB lighting with multiple cool lighting modes. Adapted systems: Windows XP, Win7, Win8, Win10 The Caps Lock light is located at this button, and when turned on, the button will light up in white. The actual effect will prevail The wireless coding light is located at the Q/W/E/R button, and the button flashes white light quickly during coding. The actual effect shall prevail. Port: USB 2.0 Number of Keys: 87 Switch: Mechanical switch Lifespan: 50 million Total Travel: 3.75+0.25mm Operating Force: 50±10g Type-C Line: 150cm Dimension: 358x130x41mm Long press FN+Q to switch to BT1 Bluetooth channel 1. The Q key flashes rapidly at 2.5Hz and stops flashing after successful code matching. Long press FN+W to switch to BT2 Bluetooth channel 2. The W key flashes rapidly at 2.5Hz and stops flashing after successful code matching. Long press FN+E to switch to BT3 Bluetooth channel 3. The E key flashes rapidly at 2.5Hz and stops flashing after successful code matching. Short press FN+Q, W, E to switch the Bluetooth channel, connect the corresponding Bluetooth channel back, and the corresponding indicator light will flash slowly at 0.5Hz. After successful connection, it will stop flashing. 2.4G mode: Set the two speed switch to "ON" 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: 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.The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. Wired mode: Connect the keyboard to the computer using a data cable and wait for the automatic installation of the driver before using the keyboard. Two speed switch requires short pressing FN+TAB to switch to wired mode Power saving instructions: Power saving design: In wireless mode, if there are no buttons pressed for 2 minutes, the keyboard backlight will automatically turn off, and the keyboard will enter standby mode; 30 minutes of inactivity, the keyboard enters deep sleep, while disconnecting 2.4G or Bluetooth and turning off all LEDs. Press any key to exit sleep. USB wired mode never sleeps.
