3. MTR: Calculating the mitre angle
Press the MTR2 (16) button again. MTR and the calculated mitre angle for
the mitre saw are indicated on the display. The mitre angle is used to define
the rotation of the saw table (MTR).
4. BVL: Calculating the bevel angle
Press the MTR2 (16) button again. BVL and the calculated bevel angle for
the mitre saw are indicated on the display.
The bevel angle is used to define the incline of the saw blade (BVL).
If necessary, the mitre and bevel angle can be retrieved again, but only if the
on/off button (14) has not been pressed to change the operating mode.
Press the button MTR2 (16) to retrieve the angle. In the display, MTR and
the calculated mitre angle appear; upon pressing the button MTR2 (16)
again, BVL and the bevel angle appear.
Press the button MTR1 (15) for less than one second to switch back from
the "compound mitre" operating mode to the "standard measurement" oper-
ating mode.
Notes on "Compound Mitre" Operating Mode
The calculated mitre angle MTR can only be transferred for mitre saws, for
which the setting for vertical cuts is 0°. When the setting for vertical cuts is
90°, the angle for the saw must be calculated as follows:
90° – displayed angle MTR = angle to be set for the saw.

Grade Measurement Operating Mode

Switching the Laser On and Off
To switch on the laser beam, press the laser on/off button (18).
Do not direct the laser beam at persons or animals and do not stare
u
into the laser beam yourself (even from a distance).
To switch off the laser beam, press the laser on/off button again (18).
Never leave the measuring tool unattended when switched on, and
u
ensure the measuring tool is switched off after use. Others may be
blinded by the laser beam.
When not using the laser, switch it off in order to save energy.
Changing the Measuring Unit (see figure B)
You can change between the units of measure "°", "%" and "mm/m" at any
time. For this, press the button for changing the unit of measure (20) as
many times as needed for the required unit of measure to be displayed in the
indicator (k) or (m). The current measured value (n) will be automatically
converted.
The unit-of-measure setting is retained when switching the measuring tool
on or off.
Switching the Audio Signal On and Off
The audio signal can be switched on or off with the audio signal button (19).
When the audio signal is switched on, the indicator for the audio signal (o)
appears in the display.
The signal tone setting is maintained after switching the measuring tool off
and on again.
Measured Value Indicator and Alignment Aids (see figure F)
With each movement of the measuring tool, the measured value (n) is up-
dated. If the measuring tool has been moved significantly, wait until the
measured value no longer changes before taking note of the value.
Depending on the position of the measuring tool, the measured value and
the unit of measure are indicated in the display rotated by 180°. Thus, the
indicator can also be read when working overhead.
The measuring tool uses alignment aids (h)/(i) on the display to show in
which direction it has to be tilted in order to reach the target value. In stand-
ard measurements the target value is the horizontal or vertical, in the Hold
function it is the stored measuring value.
