2AJVKTWKB100Wireless Mechanical Keyboard

color: Black Size:332*177*47.6mm Weight: 719.84g Number of keys: 83 keys Battery capacity: 2000mAh Switch: Blue Outemu switches Working Voltage/ Current : 1)BT mode: 3.7V/162.7mA; 2)Wire mode: 5V/270mA Charging Cable:1.6m braided Type C cable Type: Mechanical keyboard Switch button: BT/ OFF/ USB (wired), when switch to BT, then it’s under BT mode, and when switch off, then turn off the keyboard, and when switching to USB, then means it’s working as a wired keyboard In Bluetooth mode, there is no keyboard action (no keys pressed or scroll wheel), and it goes to sleep after 5 minutes. In wired mode, sleep synchronously with your computer Under bluetooth mode Bluetooth can match three devices, corresponding to three different positions of key Q, W and E respectively. In Bluetooth mode, there are two ways to pair Bluetooth connections. 1. Long press Fn + Q, W and E keys (for 3 seconds) until the blue indicator light blinks slowly and enters the code matching state. After successful connection, this LED will be steady blue and the connection information will be saved in the corresponding key position. Second, short press Fn + Q, W, E the host of the corresponding position (select), USB/bluetooth indicator light blue into rapid flash back to the state (which can be connected to the connection before the host), press the code key at this time, the USB/bluetooth indicator light Blue slow flashing, into the state of code, after the connection is successful, the blue LED normally on, In addition, the connection information is saved in the corresponding position of the key, which can be connected back to the corresponding host by short pressing Fn + W, W, E. 3. After connecting the corresponding positions of Fn+ Q, W and E to the host, you can switch the connected host by short pressing Fn+ Q, W and E. Note: 1. If Fn+Q has been paired with the host, it can be paired with other hosts by long pressing Fn+Q or short pressing Fn+Q and then pressing the pairing button. 2. If the keyboard does not move after the Bluetooth is successfully connected to the host device, the Bluetooth will first go to sleep after 3 minutes. When the key is pressed at this time, there will be a phenomenon of stalling, because the Bluetooth is in the state of connecting back, and it will take some time from the beginning to the success of connecting back. 3, when the USB cable is not connected to the computer and other hosts, the backlight may not be bright, then you can switch the keyboard to Bluetooth mode. 4, Bluetooth adapter if you have Bluetooth 4.0 version above, and to use in Win10. when connecting with bluetooth, the device name is showed TWKB100 Switch button: Mac/ Windows, switch Mac, means working on Mac system, when switching Windows, then working on Windows system Backlit: Rainbow backlit, each line with each color LED, from top to bottom, the color is blue/ red/ orange/ green/ purple/ white Right roller: is for volume control, turn right is for increasing the volume, turn left is for decreasing the volume Left roller: is for brightness control, turn right is for increasing the brightness, turn left is for decreasing the brightness Compatible with Mac/ Windows, the multimedia function is laser for Mac system 4 indicator light: wired/ bluetooth indicator, winlock indicator, caps lock indicator, charge low battery indicator Bluetooth Wired Indicator The blue light of indicator flashes when switching to Bluetooth mode. The LED is always on in blue after a successful connection. The LED is always on in red when switching to wired mode. Win Lock Indicator Win Lock function can be turned on or off after pressing FN+Win. Win key has no function when the Win Lock function is turned on (the LED is on). Win key is normal when the Win Lock function is turned off(the LED is off). Caps Indicator The LED is always on when the Caps is turned on and the LED is off when the Caps is off. Charge Low Battery Indicator Charging blue light on, fully charged blue light off The LED flashes red when the voltage is lower than 3.4V. Multimedia function Windows system Mac System FN + F1 My Computer F1: Screen brightness - FN+F2 Search F2: Screen brightness + FN+F3 Calculator F3: Call out all programs and all desktops that are running FN+F4 Media F4: Launch an interface similar to Apple's iOS FN+F5 Previous track F5: Keyboard brightness - FN+F6 Next track F6: Keyboard brightness + FN+F7 Play/ Pause F7: Previous track FN+F8 Stop F8: Play/ Pause FN+F9 Mute F9: Next track FN+F0 Volume + F10: Mute FN+F11 Volume - F11: Volume + FN+F12 Lock Whole keys F12: Volume- Support 14 backlit modes Long press FN + ESC for 3 seconds to restore the factory settings, the lighting effects will be switched to constant light mode only in wired mode FN+ Del: ON/OFF the light FN+Home: switch the backlit modes FN+↑: brightness + FN+ ↓: brightness- FN+←: lightning speed - FN+ →: lightning speed+ There is memory function in light effect speed, brightness and mode Notes: brightness cannot be switches in breathing mode, Speed cannot be switched in constant light mode FCC Caution： This device complies with part 15 of the FCC Rules.

FCC ID: 2AJVKTWKB100 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHZ)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f(GHZ) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
