Disclosure / Before Use
LitZERO is a rather unfamiliar device, and it requires ‘adjustment period’ in order to
use it smoothly. It is recommended that you read this user manual in full before use.
Please refer to the Youtube channel “Litube”as many useful videos and tutorials are
uploaded.
Precautions when using iPhone, iPad (iOS)
1) Ensure to allow “Share System Notification” that pops up during Bluetooth pairing. If
you do not allow it, clicks may not operate normally.
2) The mouse function can be used on devices with iOS 13.4 or later. Go to Settings ->
Accessibility -> Touch, and select “Assistive Touch”. In Google, search iPad mouse
settings, and set speed, cursor size and mouse key accordingly.
Precautions when charging
1) It is recommended to use 5V charger, 1A or less charger. In case of a high-speed
charter that supports high voltage and current, charging may be blocked to prevent
overcurrent or overloading of the product.
2) It is recommended to charge the product when the product is turned off. The LED
light will turn red when you push the charger all the way, when turned off.
3) If the LED light does not turn red when connected to the charger, try a different
charger (5V, 1A), and if the problem persists, contact support.
Firmware Update
1) Firmware updates are provided regularly via “LitAPP”. To check for firmware
updates, please connect the device to Bluetooth, install and run the latest LitAPP.
Others
1) Smart devices recognize LitZERO as a hardware keyboard. If the on-screen
keyboard does not appear, please set “Show on-screen keyboard” in the smart
device setting.
2) If it is difficult to identify the LED color, you can check and change the mode
status in the LitAPP.
