Warranty
Trimble warrants the DR400 to be free of defects in material and workmanship for a
period of 5 years. For the first 3 years, Trimble or its authorized Dealer or Service
Center will repair or replace, at its option, any defective part, or the entire product,
for which notice has been given during the warranty period. For the 4th and 5th
year an exchange fee may apply. This warranty period is in effect 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.
Any evidence of negligent or abnormal use, or any attempt to repair equipment by
other than factory-authorized personnel or Trimble certified or recommended parts,
automatically voids the warranty.
Special precautions have been taken to ensure the calibration of the angle sensor and
laser in the DR400; however, calibration is not covered by this warranty.
Maintenance of the calibration is the responsibility of the user (see the Calibration
section in this manual).
The foregoing states the entire liability of Trimble regarding the purchase and use of
its equipment. Trimble will not be held responsible for any consequential loss or
damage of any kind.
This warranty is in lieu of all other warranties, except as set forth above, including an
implied warranty. Merchantability of fitness for a particular purpose is hereby
disclaimed.
Customers should send products to the nearest authorized Factory, Dealer or Service
Center for warranty repairs, freight prepaid. In countries with Trimble Service
Subsidiary Centers, the repaired products will be returned to the customer, freight
prepaid.
Calibration
Before each use, be sure to check the DR400 for signs of damage. If the DR400 has
been dropped or subjected to other rough treatment, it should be checked for
accuracy. For instructions on checking calibration, please visit our website support list
at www.trimble.com/support.shtml.
Request for Service
To locate your local dealer or authorized Trimble Service Center outside
the U.S.A for service, accessories, or spare parts, contact one of our offices
listed below.

Laser Safety
Use of this product by people other than those trained on this product may
result in exposure to hazardous laser light.
• Do not remove warning labels from the unit.
• The DR400 is Class 3A/3R (<5mW @ 639 nm).
• Never look into the laser beam or direct it to the eyes of other people
• Always operate the unit in a way that prevents the beam from getting into
people’s eyes.
• NOTE: It is required to post a Laser Safety Sign and to read, sign and carry
a Laser Operator’s Card when this laser is operated in public places. To
download and print the required materials please visit our website support line
at www.trimble.com/support.shtml.

Step Back Delete:
Press and release ON/OFF to allow display, change or deletion
of Benchmark Elevation and change (if enabled) or deletion of
Benchmark Height of Instrument (BMHI) and offset numbers.
1st press allows change/deletion of Benchmark or Offset elevations.
2nd press allows change (if enabled) or deletion of Benchmark H.I.
1. Before Benchmark deleted
2. 1st press prompts BM ELV adjust.
3. 2nd press deletes BM ELV and prompts BM HI adjust.
4. 3rd press deletes BM HI
Offset (stored additional benchmark):
A benchmark must be entered and its elevation must be set to Zero before
offset can be used. The offset value is stored in memory and remains after a
power cycle. The previous benchmark can be restored by deleting the offset.
Simultaneously press and release the Benchmark
and Point buttons to create an offset from an
existing benchmark elevation. Accept or change
the offset value as desired using the up/down/
enter buttons.
Once the offset value is accepted, the offset HI
(the distance from the laser plane to the offset) are displayed. (the previous
BM is not displayed).

Exiting DigiRod mode:
Cycle ON/OFF to exit DigiRod mode and go to
Laserometer mode,
or press the ON/OFF and Units buttons to exit
DigiRod mode and go directly to laser distance meter
mode.

Sensitivity of Reception:
Medium*: for most applications
High: When the laser beam is weak, or at very long distances
Low: If outside sources are disturbing elevation readings
Out-of-Beam Indication: Sequence to show the direction to get back into the
laser beam (for 25 seconds)
ON: Out-of-Beam Display ON
OFF*: Out-of-Beam Display OFF
Grade Alert: When turned ON, disables the audible signal when on-grade.
When moved out of the on-grade dead-band, the beeper activates as normal:
OFF*: Alarm off (solid beeper ON)
ON: Alarm on (solid beeper OFF)
Automatic Shutoff
0.5 h*: shutoff after 30 minutes
OFF: Unit is permanently ON
24 h: shutoff after 24 hours
DigiRod Menu Mode:
Press switches together for 2 seconds while in DigiRod mode (after pressing
either the Benchmark or Point buttons)

or
then
BM ELV Adjust - Benchmark elevation adjustment ON*- OFF
Tilt Comp. - Tilt compensation ON*- OFF
BM HI Adjust - Benchmark height of instrument adjustment ON- OFF*
Only appears in the DigiRod Menu if BM ELV Adjust is ON
BM ELV Adjust: When turned ON, allows the benchmark elevation to be
adjusted by the user, permitting direct elevation rod functions and preset
digging depths to be entered
ON*: Prompts user for benchmark elevation after a benchmark is shot
OFF: No prompt is available to the user, limiting the DigiRod functions to
cut/fills and indirect rod (HI) readings only
Tilt Compensation: When turned ON (recommended), allows the DigiRod to
compensate for tilt for better accuracy. When turned OFF allows the DigiRod
functions to be used in inverted or sideways mounted applications (although
with NO compensation)
ON*: Tilt compensation is ON
OFF: Tilt compensation of OFF
BM HI Adjust: When turned ON, allows the benchmark HI (the vertical
distance from the laser plane to the benchmark) to be adjusted by the user
ON: Prompts user for a benchmark HI after a benchmark is shot
OFF*: No prompt is available to the user, so the benchmark HI determined
by the internal laser distance meter is always used

Move Clamp Positions:
Offset on-grade clamp position - clamp position is sensed
automatically and displayed. Offset clamp position moves the
on-grade location to allow more grade information to be displayed
above grade. This is useful in applications where going below grade is
not required, i.e. driving stakes down to grade.
Rod Clamp
1. Captive Rod Clamp Screw - attaches to
the back of detector.
2. Alignment Points (2) - help secure and
align rod clamp.
3. Level Vial - can be viewed from above or
below to verify that the rod is plumb.
4. Clamping Screw Knob - secures clamp
to rods by moving the traveling jaw. Clockwise tightens; Counterclockwise
loosens.
5. Reference Bar - top of bar is aligned with on-grade.
6. Traveling Jaw - moving jaw grips tightly to rods.
7. Reversible Face - slanted face for round and oval rods; flat face for
rectangular and square rods.
Handle
1. Mounting Locations – Insert the base feet of the DR400
into slots
2. Captive Rod Clamp Screw – attaches to the back of the
DR400.
