HOLD
to track measurements
- for continuous readings while moving.
Fastest way to measure but no reading
validation . Useful for locating correct
surfaces when there are obstacles in the
way.
Press and
RELEASE
to validate measure-
ment only when unit is held absolutely still.
Most accurate mode
. Useful in environ-
ments when obtaining a stable reading
can be difficult. Validates all measurement
before displaying. Filters out noise from
machinery and other sources.
Multiplies
measurements for area and
volume. Stores and recalls memory.
Adds
linear distances, areas and volumes.

release to clear display. Press twice to turn
unit off.
Press and hold key for more than 2
seconds to change display units. The display
will cycle between

TAKING A MEASUREMENT -
Getting Started:
1) Install a fresh 9V alkaline battery in rear of
unit. Push contacts firmly in place.
2) Aim cone at a hard, flat, unobstructed surface
such as a wall or mirror.
3) Make certain you have a clear path to the
surface (wall). (See FIG. 1)
4) Hold Receiver perpendicular to the surface.
(See FIG. 2)
NOTE:
Measurement will be taken from bottom
of unit.
5) Press and hold until a consistent measure-
ment appears (about 2 seconds). The unit will
continue to take and display rapid measure-
ments as long as the button is held. Release
button to freeze the measurement.
Press and release to validate
measurements.
6) Your unit is factory preset to display metric. To
set your display to desired mode (m or ft:in)
Press and hold button until desired mode
displays, then release.
NOTE:
Unit will now
default to your preset mode even after unit is
turned off.
HELPFUL MEASURING HINTS:
1) Measurements cannot be taken through glass
or off of soft or padded surfaces.
2) The SONIN 45s range and ability to measure
in tight spaces can be increased. Stand in the
middle of the distance to be measured and
add measurements taken in opposite directions.
3) When measuring in confined spaces (hallways),
try to measure down the center line and midway
between the floor and ceiling.
4) To find a specific distance from a wall, walk
toward or away from the wall while holding
down .
5) When the surface being measured to has
protrusions and recesses, you can determine
where the beam is hitting. Move sideways,
parallel to the target, while holding down
. You will see the distance increase for
recesses and decrease for protrusions.
6) Be sure the surface you are measuring to is
hard, flat and uniform. Some surfaces such as
stucco or clapboard may scatter signals.
7) The unit may lock on to a stronger (usually
closer) target. If this happens, release the
measuring button and try again.
8) Remember that the unit measures from the
bottom of the unit (end opposite cone).
