Do Not Stare into beam. Class ilia Laser Product

1. DO NOT remove or deface any product labels,, Removing product labels
increase the risk of exposure to laser radiation,

2. DO NOT stare directly at the laser beam or project the laser beam directly
into the eyes of others. Serious eye injury could result.

3. DO NOT place the ultrasonic measuring tool in a position that may cause

anyone to stare into the laser beam intentionally or unintentionally° Serious
eye injury could result°

4. DO NOT use any magnifying optical tools such as, but not limited to

telescopes or transits to view the laser beam. Serious eye injury could result,,

5. DO NOT operate the ultrasonic measuring tool around children or allow

children to operate the tool. Serious eye injury, could result°

6. ALWAYS use only the accessories that are recommended by Sears for use

with this product.

7. Keep the tool dry and do not place in direct sunlight,

8. ALWAYS turn the tool off when not in use,

KNOW YOUR TOOL

This laser guided measuring tool is used for measurement of distance., It emits a laser
beam which projects a visible spot (_ on the target surface_ The tool generates ultrasound
to permit easy floor to ceiling and wall to wall measurement. Use to measure distances
to the object, calculate area in square feet and volume in cubic feet.

TOINSTALL BATTERY (See Figure 3)

NOTE: This tool operates on one 9-volt battery

(not included).

1. Open battery compartment door on the back of tool

2. Plug 9-vott battery into the battery conductor,

3. Close battery compartment door_
IMPORTANT NOTE: When the battery is low,the low battery

[_ will be continuously displayed on the upper left side
of the LCD display screen,

HOWTO USE LASER GUIDED MEASURING TOOL
Place the bottom of the tool at the point from which the

measurement is to begin (such as a wall or floor),
The built-in level vials will help you to align the tool at 90°.,

The ultrasonic signal is projected in circular
waves (see Fig. 4).

For tong distance measuring, between 40 to 50 feet
(12 to t5 meters), the target area should not be smaller

than 10 x 10 feet (3 x 3 meters)

IMPORTANT NOTE:

1. In order to get the most accurate result, make sure the ultrasonic wave is perpendicular
to the target,,

2. The targetarea must bea hard regularsurface with no objects or obstacles in the measured field
3, Placea piece of cardboard on front of the target ifthe measured target is small, irregularor soft_,

4.This tool cannot be usedto measurethrough glass, eventhough the laser beam can pass through

5. All measurements are calculated from the bottom of your tool (as shown in Fig, 4)

HOWTO READYOUR LASER GUIDED MEASURINGTOOL

1. Press the power key and the LCD display screen will show the temperature in degrees
Fahrenheit,

2. Point the toolperpendicularlyat the target and get the measurement by pressing the
"Read" key,

3oEach measurement erases the previous one.

4. The measurement was unsuccessful if "Err" appears on the LCD display screen

5_When "Err" appears on the display screen, press "Read" key or re-start the tool to measure

again, making sure to avoid the following conditions:
,,The target surface does not provide a good reflection for the ultrasonic measuring

signal (e i.,it isa soft, irregular surface such as thick carpet, curtains, or irregular

wallpaper, etc)
oThe distance measured is out of the specified measuring range (2 to 50 feet),,
oThere are obstructions within the specified measuring range°
=The tool is not perpendicular to the target

6. The tool automatically turns off, if not used for 30 seconds,
7oMeasurements can be ready easily even in dark conditions due to the back-lit LCD screen.

IMPORTANT NOTE: in order to get accurate measurements, always be sure to point the tool
perpendicularly to the target before starting any measurements,

3. Choose the measuring mode and read.
Measuring a single distance:
A. Press single distance key "t-----t",

B. Press "Read" key to get measured

distance (see Fig. 8)

C, Press "Read" key again to get new

measured distance_

D, Press "Recall" key and the latest measured distance will be shown on screen

MEASUREMENT OFTWO DISTANCES AND COMPUTING THEIR SUM

1. Press "HH" key

2. The left blinking line in "_----" shows the first

measurement to be taken (see Fig 9),

3. Press "Read" key to get the measured
distance (see Fig. 9),

4.The right blinking line in "__" shows the

second measurement to be taken,

5. Press "Read" key to get the second measured

distance shown in the upper row,The sum of
the two measurements will immediately show

at the bottom of the screen (Fig°10)

6, Press "Recall" key and the first

measurement will blink inthe upper row

Press "Recall" key again and again and the
two measurements wilt blink in the upper row
circularly

NOTE; When measuring large distances that are beyond the capability of the tool, measure from
the middle point of the distance to both sides and add their values using the "t--Ill" key_
