Battery installation (Fig. 2)
This multi-function digital laser level uses two "AAA" batteries (sold separately), to power both the LCD module display and
the Laser dot.
NOTE: Always ensure the on/off button is in OFF position before installing or replacing the batteries.
1. Open the battery cover, located in the middle of the back of the level (Fig.2).
2. Insert two new "AAA" alkaline batteries with the polarity (+/-) as indicated on the inside of the battery compartment.
3. Close the cover securely in place.
Turn on the LCD display
Press the Power button to turn the LCD display screen on. When the screen first comes on, the temperature is displayed in
centigrade for about 2 seconds, to indicate if level is being used in optimum operating temperature range. The current angle
of the level is then displayed, and a picture of that angle is shown either above or below the line for true level. An arrow on
the display indicates if the level has to be moved up or down. True level is reached when the two lines are together and the
angle shows 0.00°. Turn off the LCD display by pressing and holding the button in for about 2 seconds. If the digital level is
not used for 5 minutes the level automatically turns off. The LCD display is large and easy to read. When the level is turned
upside down, the LCD screen senses and changes to read correctly in the inverted position.
