PLEASE READ THIS FIRST:
Your choice of the SONIN COMBO PRO shows
you are a professional who demands quality and
value from your tools. Please take a few minutes
to read this manual. Your SONIN COMBO PRO
has many easy-to-use features that will make your
measuring tasks faster and easier once you
understand them.
The SONIN COMBO PRO is actually two measur-
ing tools in one. It can take measurements by
bouncing sound waves off flat hard surfaces such
as walls or ceilings from 1 ft 6 ins (46cm) up to
60 ft (18m) in the SINGLE UNIT MODE or
from 3 ft (1 m) up to 250 ft (75m) by sending
infrared light signals to the Target (included) and
receiving sound waves back from the Target in
DUAL UNIT MODE.
Use the SINGLE UNIT MODE primarily for
indoor measurements or whenever you are
measuring to a suitable, hard, flat surface, less
than 60 ft (18m) away.
Use the DUAL UNIT MODE when you need
to measure distances greater than 60 ft (18m),
when there is no suitable surface to bounce the
signal off of, or when there are obstacles partially
blocking the measuring path. [ If you can see the
Target (and it is within range), the COMBO PRO
can take a measurement. ]

KEYS AND THEIR FUNCTIONS:
Determines whether the unit
is operating in Single Unit or Dual
Unit mode. The Receiver will not turn on
until either
or is pressed.
Measures from bottom of unit 
icon will appear in the lower right
corner of the display.
Measures from top of unit 
icon will appear in the lower right
corner of the display.
Using either button: Press and 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 measurement only
when unit is held absolutely still. Most accurate
mode. Useful in environments when obtaining a
stable reading can be difficult. Validates all
measurement before displaying. Filters out noise
from machinery and other sources.
Turns on Memory. Cycles through memory
registers.
Stores data displayed into blinking memory
registers.
Recalls memory from blinking memory
registers.
Multiplies measurements for area and
volume. Stores and recalls
memory.
Adds linear distances, areas and volumes.
Stores and recalls
memory.
Subtracts linear distances, areas and
volumes.
Clear/Convert/Off Button. Press and
immediately release to clear display. Press
- 3 -
and hold for two seconds to change display
units. Press twice to turn unit off.
Press and Hold
key for more than 2 seconds
to change display units. The display will cycle
between m, ft:in, ft:ft and yd. Release key to
select desired mode.
GETTING STARTED
TAKING MEASUREMENTS
SINGLE UNIT MODE:
1) Install a fresh 9V alkaline battery in rear of
unit. Push contacts firmly in place.
2) Select SINGLE UNIT MODE by sliding
the switch on the side of the unit to the
position.
3) Aim cone at a hard, flat, unobstructed surface
such as a wall or mirror.
4) Make certain you have a clear path to the
surface (wall). (See FIG. 1.)
5) Hold Receiver perpendicular to the surface.
(See FIG. 2.)
