1)
Measuring inaccuracy will increase by ± 0.25 mm in the distance mea-
surement distance of 10-25 m. At a distance over 25 m, the inaccuracy
will increase by further ± 0.25 mm. Intensive sunlight, transparent
materials (clean water or colourless glass), small reflectivity of the
measured surface or large temperature differences may reduce mea-
surement accuracy. When the temperature of the measured surface is
high, inaccuracy may increase by ± 1.5-2 mm.
2)
The battery lifetime depends on the quality of the batteries used, the sto-
rage/operating conditions of the device and the operating time of the device.

ATTENTION
yBefore using the device, read the entire user's manual, and if you loan or
sell the product to anybody, also include the user's manual with it so that
they can learn about it. Prevent this user's manual from being damaged.
III. Simple measurement, turning on
and off
yTo turn on the device, press the
Then press the button to select whether the measured distance will
include the length of the device or whether the measurement will be taken
from the front side of the device (see respective symbol on the display). One
can toggle between both measurement modes by pressing the same button
. In the event of too much ambient light or a transparent surface, press
and hold the "disk" button to set a more intensive laser beam. The active
intensive beam function is signalled by the
panied by any other sound signal than when this function is not activated.
Deactivate the intensive beam function by holding down the same button.
Use the button to set the length unit m/ft/in/ft-in. The length unit
can be changed even after taking a measurement.
Then point the laser beam at the measured surface and press
this button again to take further measurements, whilst the preceeding
three measured values will be shown in the three rows on top of each other.
Press button to gradually delete the measured values from top down.
To turn the device off, hold down button

After measuring a given distance, it is possible to add or subtract another
measured value from it in the following way:
Measure a distance by pressing button
to add the next measured distance or button
quently measured value. The + or – symbol will be shown on the display.
The subsequently measurement made by pressing button
or subtract the measured value. In the event that in the subtraction mode
the subtracted value is higher than the first measured value, the result
will be negative (final value will have a "–" sign).
IV. Saving measured values to memory
yWhen taking the individual measurements by repeatedly pressing button
(when it is necessary to collect multiple measurements), these
values will automatically be saved to the device's memory and can be later
reviewed by pressing the "disk" button
values can be stored in memory. The four most recent measured values
will also be shown on the display in the active measurement mode.
yWhen a given set of values is measured, then pressing the "disk" button
will save the given values to the device's memory in reverse order,
i.e. when a total of only 6 out of 20 possible values are measured, the sixth
(last measured) value will be stored in memory under number 1, the fifth
value under number 2, etc. The remaining 14 values out of the storage
capacity of 20 will be values from previous measurements. Scroll through
the stored values by repeatedly pressing the "disk" button
buttons or to move up or down through the numerical row.
The stored measured values cannot be deleted from memory by pressing
button , rather, the initially stored values are replaced by newly
measured values in reverse sequence (see above).
V. Continual measurement function
yWhen button is pressed, the continual (non-stop) measurement
function is activated, where the device constantly measures the distance
