uTake the batteries out of the laser receiver when you are not using it for a pro-

longed period of time. The batteries can corrode and self-discharge during pro-

longed storage in the laser receiver.

Operation

Starting operation

uProtect the laser receiver against moisture and direct sunlight.

uDo not subject the laser receiver to extreme temperatures or variations in tem-

perature. As an example, do not leave it in vehicles for longer periods. In case of large

variations in temperature, allow the laser receiver to adjust to the ambient temperat-

ure before putting it into operation. In case of extreme temperatures or variations in

temperature, the accuracy of the laser receiver can be impaired.

Setting up the Laser Receiver (seefigureA)

Place the laser receiver at least5m away from the line laser or point and line laser. En-

sure that receiver mode is active on the line laser or point and line laser. Select an oper-

ating mode in which either only a horizontal or only a vertical laser beam is generated.

Note: Do not select an operating mode which generates both horizontal and vertical

laser beams at the same time (cross-line operation) because this might impair the height

readings of the laser beam.

Position the laser receiver so that the laser beam can reach the reception area(5). Align

it so that the laser beam runs straight through the reception area (as shown in the fig-

ure).

Switching On/Off

uA loud audio signal sounds when switching on the laser receiver. Therefore, keep

the laser receiver away from your ear or other persons when switching it on. The

loud sound can damage hearing.

To switch on the laser receiver, press the on/off button(3). All display indicators and all

LEDs light up briefly and an audio signal sounds.

After the laser receiver is switched on, the volume is always set to medium and the re-

ception accuracy set to "fine".

To switch off the laser receiver, press the on/off button(3) again. All LEDs and all dis-

play indicators light up briefly before the tool switches off, and an audio signal sounds.

If no button on the laser receiver is pressed for approx.20min and no laser beam

reaches the reception area(5) for 20min, then the laser receiver will automatically
