Ⅱ. Input Operation
To provide external power for the product, please use the included
power cable to connect it to 100V-240V 50/60Hz AC power source, and
turn on the ON/OFF switch ( when the "∣" on the switch is pressed
down). When turning off the ON/OFF switch ( when the "O" on the
switch is pressed down), the internal battery provides power to the
product.
Tips: The ON/OFF switch on the back doesn’t control the clock screen
brightness. If you want to adjust the clock screen brightness or turn it
off, you can use the knob switch. Please see article IV 4.1 for details.
