Safety Precautions 3
Electronic Copy of LTI's UltraLyte LR B User's Manual - 2nd Edition © 2002
Safety Precautions
Avoid staring directly at the laser beam for prolonged periods.
The UltraLyte LR B is designed to meet FDA eye safety
requirements and is classified as eye-safe to Class 1
limits, which means that virtually no hazard is associated
with directly viewing the laser output under normal
conditions. As with any laser device, however, reasonable
precautions should be taken in its operation.
It is recommended that you avoid staring into the
transmit aperture while firing the laser. The use of
optical instruments with this product may increase eye
hazard.
Never attempt to view the sun through the scope.
Looking at sun through the scope may permanently damage your
eyes.
Never point the instrument directly at the sun.
Exposing the lens system to direct sunlight, even for a brief period,
may permanently damage the laser transmitter.
Do not expose the instrument to extreme temperatures.
UltraLyte LR B components are rated for a temperature range of
-22° F to +140° F (-30° C to +60° C). Do not expose the instrument
to temperatures outside that range.

Section #1 – Getting Started
Laser Technology’s UltraLyte LR B is part of the UltraLyte family of
handheld laser speed and ranging devices. Compared to the other
UltraLyte models, the UltraLyte LR B:
•Has simplified menus and options.
•Includes a built-in Weather Filter that is an alternate speed
measurement mode. The Weather Filter is a simplified
UltraLyte gating option. This factory-defined gate ensures that
targets are beyond the range where rain and snow can affect
the laser's ability to capture a speed reading.
•Displays one speed reading after another until you release the
TRIGGER.
Other Features of the UltraLyte LR B include:
•Liquid Crystal Display (LCD) screen for instant access to
measurements and options.
•Serial output port for easy connection to a data collector or
remote computer.
•Fully adjustable, fold-away shoulder stock.
•Sighting scope with in-scope red aiming dot and
in-scope measurement display.
•Two 3-button panels that provide quick and easy access to the
instrument functions.
•Sounds and visual indicators that ensure confidence of positive
target acquisition.

Section #1 – Getting Started 7

Sensors
The UltraLyte LR B has two lenses on the front panel. The top lens
transmits the infrared laser signals. The bottom lens receives signals
back from the target and feeds signal information to the internal
circuitry.
The internal circuitry consists of a laser range sensor and timing,
analysis, computation, and display circuits. The UltraLyte LR B
determines distance through its laser range sensor, by measuring the
time of flight of short pulses of infrared light. The UltraLyte LR B has a
broad spectrum of sensitivity, and can work with both reflective and
non-reflective targets.
The maximum measurement distance varies with target and
environmental conditions. The absolute maximum is about 3280 feet
(1000 meters).
LCD Screen
The LCD Screen displays menu items, option indicators, error codes,
and speed and survey measurement results.
Serial Port Connector
The serial port connector allows you to connect the instrument to a
data collector or remote computer. For more information about the
Serial Data Interface, see page 45.

Filter adjustment ring
Sighting Scope
Mounted on top of the UltraLyte LR B is a single-power sighting scope.
The scope features:
•Adjustable polarizing light filter to optimize viewing contrast.
Figure 2 shows the polarizing light filter's adjustment ring.
•In-scope red aiming dot to help you aim accurately to the
target.
•In-scope measurement display. As Figure 3 shows, the
appearance of the aiming dot varies, depending if the
Speed Mode or Survey Mode is active. In these examples,
the number '87' represents the measured value, either a
speed or a distance, depending on the active mode.
You can vary the intensity of the red dot to account
for different lighting conditions. For more information,
see page 18.

Inserting the Batteries
Two C batteries are required to power the UltraLyte LR B. Refer to the
instructions and Figure 8 below when inserting the batteries.
1. Remove the battery compartment cap by twisting counter-
clockwise.
2. Insert the two batteries, positive end first, into the battery
compartment in the instrument handle.
3. Replace the cap.
4. Twist the cap clockwise until it stops and is secure.
Be careful to not over-tighten the cap.
Battery Voltage Level
The UltraLyte LR B continuously monitors its power source. LTI has
defined an acceptable battery voltage range to ensure that the
instrument has sufficient battery voltage to guarantee correct operation.
•
The “BATT” display feature flashes on the screen if the battery
voltage drops to the upper end of the acceptable battery
voltage range. It continues to flash as long as battery voltage
is within the acceptable range. You should replace the
batteries as soon as possible. The display backlight is not
accessible during low battery situations.
•
The “BATT” indicator stops flashing, and stays displayed on the
screen
if the battery voltage level drops below the acceptable
battery voltage range. If you fail to replace the batteries, the
button panels will lock out.

Figure 10. Aiming Dot Intensity Setting
Adjusting the Aiming Dot’s Intensity
The in-scope red aiming dot has eight intensity settings from OFF (00)
to
BRIGHT (07). Refer to the instructions and Figure 10 below to adjust
the red aiming dot’s intensity.
1. Press the BRIGHTNESS CONTROL button. The display
should look similar to Figure 10. The current setting is
whatever “br xx” is displayed. The factory default setting
is “br 05” as shown in the figure.
2. Press the BRIGHTNESS CONTROL button until the setting
is correct. It's easy to get the correct setting if you look
through the scope while making the adjustment.
3. Press the TRIGGER to return to the measurement mode that
was most recently active. Otherwise, press the button that
corresponds with whatever it is that you want to do next. For
more information, see Table 2 on Page 14.
•Each time you press the SCOPE BRIGHTNESS button,
the “br xx” value increases by 1.
•If you press the SCOPE BRIGHTNESS button while
“br 07” is displayed, you will see “br 00” next.
•Powering OFF the instrument does not change this
setting. The next time the instrument is powered ON,
the setting will be the same.
