1) If the unit is unable to take a "good" measur-
ement the display will show one of the following:
BLANK SCREEN Make certain
the Receiver switch is in the
or the position.
Check/replace battery. If unit
still doesn't work, call your
SONIN Dealer.
When the BATT symbol appears
on the display, replace the battery.
Out of Range or No Return
Signal.
No Valid Reading.
Possible causes for Error 1 and Error 2 include:
a) Measurement out of range [1.5 to 60 ft
(0.46 to 18.2 m) without Target, 3 to 250
ft (1 m to 75 m) with Target].
b) Unit is not perpendicular to the surface or
Target. (See Fig. 2.)
c) Surface is not hard and flat.
d) Interference from nearby noise sources. Try to
position the Receiver as far from the noise
source as possible or turn off the machinery
causing the noise (see section on ENVIRON-
MENTAL CONDITIONS).
e) Receiver or Target was moved during the
measurement. The distance between the two
units must not be change during the reading.
f) Excessive wind.

g) Target is not turned on.
h) The Target is being triggered by an infrared
light signal other than the Receiver. If direct
sunlight is "blinding" the Target, exchange
the position of the Receiver and the Target
so the light is coming from behind the Target.
Math error - square or cube
result overflow.
COMPUTATION FUNCTIONS:
To make the computations in the descriptions
below, the button symbol indicates taking an
actual measurement (length, width or height) with
either the or the button.
Multiplying: The unit multiplies linear
measurements to compute areas and
volumes. The
symbol will appear in
the upper left corner of the display.
Adding: The unit adds linear measure-
ments, areas or volumes. The
symbol
will appear in the upper left corner of
display.
Subtracting: The unit subtracts linear
meaurements, areas or volumes. The
symbol will appear in upper left corner of
display.
Adding distances:
(Display shows , , or )
(Continue until you are done adding
distances.)
Subtracting distances:
(Display shows , , or )
(Continue until you are done subtracting
distances.)
Multiplying to compute areas:
(Display shows , or )
3) To Exit Memory, continuously press the
key until Memory Registers no longer appear
on the LCD, NOTE: the unit will automatically
exit memory mode when you clear the memory,
store to memory or recall the memory.
To Store Memory:
Take a measurement. Press and release the
key until you reach the desired memory register.
Then, while blinking, press the key once to
store the displayed reading. The memory icon will
now turn off to indicate that it has data stored to
that register and back to the measuring mode.
Example: To store in M3
Press
once, and press 4 times -
(the icon will blink) then press .
Your measurement will be stored in M3.
To Recall Memory:
Press and release the key until you reach the
desired memory register. Then, while blinking,
press the key. This will recall the data stored
in that memory register.
Example: To recall from M3
Press
until is blinking. While blinking
press
key. Memory stored in M3 will
display on LCD.
To Clear All Stored Memory :
Press key until all 5 Memory icons are blinking.
Then press
key. All memory stored will be
erased and your unit will automatically go back
to measuring mode.
To store in :
Press , then (the symbol will
appear in the upper left corner of the display)
To store in :
Press , then (the symbol will
appear in the upper left corner of the display)

Multiplying to compute volumes:
(Display shows , or )
To add areas:
(Display shows total area)
(Continue until you are done adding areas.)
To add Volumes:
(Display shows total volume)
(Continue until you are done adding volumes.)
Note: The SONIN COMBO PRO can only add
like units of measure.
MEMORIES:
Your SONIN COMBO PRO has SEVEN Memories.
5 Memory Registers - M1, M2, M3, M4 and M5
and two calculation memories in
and .
To Access M1 - M5 Memory Registers:
Press
Key Once to Turn On Memory. If any
memory is already stored, the icon will appear
on the LCD showing where there is stored data,
otherwise it remains blank indicating all memory
registers are empty.
Continue to press and release the
key to
access the memory registers. The icons will blink
when accessible. (i.e. , , , and/or
blinking)
NOTE:
1) When M1 - M5 icons are blinking and the
key is pressed, it will clear the memory
in that register.
2) If you plan to store a new measurement, you
must first take the measurement before entering
into memory.
