POWER SUPPLY

INSERT / REPLACE THE BATTERIES
Open the battery compartment cover on the rear of the receiver and insert 4 x AA alkaline batteries. Refer to the battery compartment diagram to ensure correct polarity. Close the battery compartment cover. Always remove the batteries if the receiver will not be used for a long period of time to avoid leakage. Take care to replace empty batteries in due time.

POWER ON
Press the ON/OFF button once to power on the receiver. The LCD display will initialise for about 0.5 seconds when all the display symbols are illuminated. A double beep will sound. The receiver is now ready for use (see right diagram).

SELECT THE DETECTION ACCURACY
Power on the unit and select the detection accuracy fine or normal by pressing the „accuracy button“. Fine detection: ± 1 mm (working at close distance) Normal detection: ± 3 mm (working at far distance) The display will show the symbol of the accuracy setting made

POWER ON /OFF THE SOUND
Power on the receiver and press the button „sound“ to power on the sound. The symbol in the LCD display shows the status of the sound: if no symbol is displayed the sound is off.

SELECTION OF CLOSE / FAR DISTANCE WORKING

• Close distance: up to 30 m
• Far distance: from 30 m

RECEIVE A LASER BEAM
Power on the receiver and make all required settings (i. e. accuracy fine, sound on). Carefully move the receiver up and down to detect the laser beam.

If the instrument receives a laser signal the height difference within the working range (± 25 mm) will be displayed by an exact numeriacal value. If the laser beam is outside the working range „OUT“ will be displayed.

The laser beam is low.

• The lower LED is illuminated.
• Acoustic signal: slow short beep.
• The distance in mm to the 0-position will be displayed ->Move the receiver down.
