10. Trouble Shooting

• If the unit does not turn on, check the battery polarity or install new

alkaline batteries and clean the battery terminals.

• If the unit will not turn off, hold the power button in for several

seconds until the unit turns off.

• If the LCD shows an “Erro” code, this indicates that the unit is being

tilted too far forward or backward. Position the level flat on its

intended read surface.

• If the unit is out of calibration or the numbers are inverted, confirm

that the unit is not in “hold” mode when the H is solid. Push the

“hold” button to disengage the “hold” function before attempting

calibration. Follow the calibration procedure in the user manual

(section 5).

• If the unit will not calibrate, contact our Customer Service

Department.

• If the unit turns off after a short time, install new alkaline batteries

and clean the battery terminals.
