Learning the Receiver Functions
Turning On/Off the Receiver
1.
Press the power/audio
button to turn on the
receiver.
Note:
When the receiver
is initially turned on/off,
all LCD symbols, LEDs,
and the audio signal are
turned on for one second
(diagnostic mode). After the
diagnostic mode is complete,
the grade sensitivity (fine) and the audio (loud) symbols appear.
2.
Press and hold the power/audio button for one second to turn off
the receiver.
Turning On/Off LEDs
The LEDs show the position of the receiver relative to the laser beam.
Turning off the LEDs extends battery life.
The factory default setting for the LEDs is on.
1.
Press the grade-sensitivity and power/audio buttons repeatedly to
turn the LEDs on or off.
Note:
When the LEDs are turned on, all LEDs light for one second;
when the LEDs are turned off, both red LEDs light for one second.
Selecting the Grade Sensitivity
The receiver always starts up with the on-grade sensitivity (fine) active.
1.
Press the grade-sensitivity button repeatedly to select between fine:
1.5 mm (
1
/
16
in.) and medium: 3 mm (
1
/
8
in.) grade sensitivity.
Selecting the Audio Function
The receiver always starts up with the audio mode (loud) active.
1.
Press the power/audio button repeatedly to cycle through the audio
levels, which include off, soft, and loud.
Note:
If the audio function is on, the receiver beeps quickly when
the receiver is above the laser beam, slowly when below it, and
continuously when centered in the laser beam or on grade.
Using the Receiver with a Laser
1.
Press the power/audio button to turn on the receiver.
2.
Position the receiver so that its photocell faces the laser.
3.
Move the receiver up/down until the LCD and LEDs show an
on-grade reading.
Note:
The LCD shows a down arrow when the receiver is above the
laser beam, an up arrow when below it, and a horizontal line when
centered in the laser beam.
Note:
The top/bottom LED flashes when the receiver is within
6 mm (
1
/
4
in.) of being on grade and light continuously when the
receiver is between 6 mm and 25 mm (
1
/
4
in. and 1 in.) of being
above or below the laser beam. The green LED flashes when the
receiver is on grade.

Determining the Height of Instrument (HI)
The height of instrument (HI) is the elevation of the laser’s beam.
The HI is determined by adding the grade-rod reading to a benchmark
or known elevation.
1.
Set up and level the laser.
2.
Attach the receiver to a grade rod and turn on the receiver.
3.
Place the grade rod on a job-site benchmark (BM) or known
elevation.
4.
Slide the receiver up/down the grade rod until the LCD shows an
on-grade reading.
5.
Add the grade-rod reading to the benchmark to determine the
height of instrument.
Example: Benchmark elevation = 30.55 m (100.23 ft)
On-grade rod reading = + 1.32 m (4.34 ft)
Height of instrument = 31.87 m (104.57 ft)
6.
Use this HI as a reference for all other elevations.
Checking Calibration
As with any precision instrument, the calibration needs checking on a
regular basis (such as at the beginning of a job, or if the laser has been
handled roughly). If the laser is being used at temperatures below
freezing, be sure to check calibration under those conditions. The laser
is calibrated if the laser plane is within ±2.2 mm (±3/32 in.) of true
level at 30 m (100 ft). If the laser has a calibration error, go to the
“Request for Service” section of this manual to get more information.
CAUTION:
When checking all four axes for a calibration error, be
sure not to rotate the laser more than 360°. Doing so can cause the
extension spring that holds the laser to the leveling base to break. If
rotating the laser becomes difficult, turn the laser 180°in the opposite
direction.
1.
Set up and level the laser 30 m (100 ft) from a wall.
2.
Use the receiver to take an elevation reading for the +Y axis.
3.
Rotate the laser 180° (–Y axis toward the wall) and re-level the laser.
4.
Use the receiver to take an elevation reading for the –Y axis.
5.
Calculate the difference between the two elevation readings. If they
differ more than 4.4 mm (
3
/
16
in.), the laser needs calibrating.
Return the laser to an authorized Trimble service center for servicing.
6.
To check the X axis, repeat steps 1–5 using the X axis instead of the
Y axis.

Laser Safety
The United States Government Center of Devices for Radiological
Health (CDRH) has classified this laser as a Class1 laser product.
The classification is the safest one available in that it uses laser energy
similar to that used in a compact disc player. A Class 1 certification
means that NO risk of injury exists when this laser product is used in
accordance with the instructions in this manual.
CAUTION:
If you’re using an optical instrument within 30 m (10 ft)
of the laser, do not point it toward the laser.
No OSHA or ANSI requirements with regard to signs, warning labels,
or operator’s licensing are needed because of the laser’s low operating
power. Question about laser safety should be address to:

Warranty
Trimble warrants the laser system (laser, receiver, tripod, and grade rod)
to be free of defects in material and workmanship for a period of one
year. The Warranty is in effect twelve months from the date the system
is delivered by Trimble or its authorized dealer to the purchaser, or is
put into service by a dealer as a demonstrator or rental component.
If the laser fails due to damage to the beam reflecting compensator or
laser source, those components will be repaired or replaced at no
charge during the original warranty period.
Special precautions have been taken to ensure the calibration of the
laser; however, calibration is not covered by this warranty. Verifying
the laser’s calibration is the responsibility of the customer.
Trimble or its authorized service center will repair or replace, at its
option, any defective part for which notice has been given during the
warranty period. If required, travel and per diem expenses to and from
the place where repairs are made will be charged to the customer at the
prevailing rates.
Customers should send the product to Trimble or the nearest
authorized service center for warranty repairs, freight prepaid. In
countries with Trimble subsidiary service centers, the repaired product
will be returned to the customer, freight prepaid.
