4. OPERATION

WARNING! Danger of injury due to defective components! The product must only be put into operation if no defects are found. Ensure that any defective parts are replaced before the product is used again.

It's recommended to carry out an accuracy check before first use and periodic checks during future use, especially for precise layouts. Also when the laser may have been dropped.

Check the device:

Make sure all parts are fitted on the machine firmly.
- Check whether there are any visible defects: broken parts, cracks, etc.
- Check the accuracy when it is the first time you are using the laser or when the laser has not been checked for accuracy in a while.

• Also check the accuracy when the laser may have been dropped.

Switch on and off (Fig. A)

Press the measure button (2) to switch on the device. Device will always start in the default reference setting of single measurement mode. Hold down the switch off button (8) to switch off the equipment.

Automatically switch off

The laser will be switched off automatically after 15 seconds and the device will be powered off after 30 seconds of inactivity.

Clear button (Fig. A)

Press clear button (8) to clear the last command or displayed data.

Unit conversion (Fig. A)

The instrument's default unit is meters but can be set to meters 'm', feet 'ft' and inches 'in'. Press the units button (7) to switch between units of measurements.

Adjusting measuring reference (Fig. A+C)

When the device is switched on, quickly press the measuring reference button (4) to adjust the measure reference. It's possible to measure from the front or the rear of the device.
