Foreword
Thank you for purchasing the Topcon RL-VH3C Rotating Laser.
It is one the world’s most advanced lasers.
To quickly and effectively use the RL-VH3C, please read these brief instructions carefully; and keep them in a convenient location for future reference.
Handling Precautions
1 Vibration and Impact Protection
When transporting the instrument, provide protection to minimize risk of severe vibration
or impact. Severe vibration or impacts may affect beam accuracy.
2.Laser Scanning Interference
Particular reflective surfaces such as mirrors and some glass surfaces, can cause beam
reflection that in very rare circumstances can interfere with the laser scanning function. If
this should happen, simply change the location of the laser or cover the reflective surface.
Caution:
Use of adjustment controls or performance procedures other than those specified herein
may results in hazardous radiation exposure.

Safety Cautions
WARNING
• There is a risk of fire, electric shoc k or physical harm if y ou attempt to disassemble or repair the instrument yourself.
This is to be carried out by TOPCON or an authorized dealer, only!
• Laser beam can be dangerous, and can cause eye injury if used incorrectly.
Never attempt to repair the instrument yourself.
• Cause eye injury or blindness.
Do not stare into beam.
• Risk of fire or electric shock.
Do not use a wet battery.
• May ignite explosively.
Never use an instrument near flammable gas or liquid matter, and do not use in a coal
mine.
• Battery can cause explosion or injury.
Do not dispose in fire or heat.
• The short circuit of a battery can cause a fire.
Do not short circuit battery when storing it.

CAUTION
Use of controls or adjustment or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
Let the laser beam reach the aimed object or the target without anybody else in the laser
beam path. When operating in an open area, avoid radiating laser beam at eye level. It
is quite possible for the beam to enter into one's eyes, and it is possible to lose visual
sight temporarily , and lose one's caution and aw areness of other dangers - avoid glaring
beam.
Do not allow skin or clothing to come into contact with acid from the batteries, if this does
occur then wash off with copious amounts of water and seek medical advice.
Risk of injury by dropping the instrument or case.
Do not use a carrying case with damaged belts, grips or latches.
It could be dangerous if the instrument falls over , please check that you fix the instrument
to the wallmount or tripod.
Risk of injury by dropping a tripod and an instrument.
Always check that the screws of tripod are tightened.
Please note that the tips of tripod can be hazardous, be aware of this when setting up
or carrying the tripod.

Laser Safety
This product projects a visible laser beam during operation. This product is manufactured
and sold in accordance with “Performance Standards for Light-Emitting Products” (FDA/BRH
21 CFR 1040) or “Radiation Safety of Laser Products, Equipment Classification, Requirements and User’s Guide” (IEC Publication 825) provided on the safety standards for laser
beam.
As per the said standard, this product is classified as “Class 2 (II) Laser Products”.
This is a simple product to operate and does not require training from a laser safety officer.
In case of any failure, do not disassemble the instrument. Contact TOPCON or your
TOPCON dealer.

Head rotates slowly,
searching for Magnetic
Scanning Target. When
target is placed in beam
path, laser rapidly scans
back and forth on target.
Laser sensor mode
Head rotates at 300 rpm.
Use this setting when using
an optional electronic laser
sensor such as the Topcon
LS-70.
Head stops rotating and the
beam can be positioned by
manually turning the head.
Select X or Y axis for
manual beam sloping.

Instrument Set-up Procedure
Horizontal Rotation
1 Set the instrument on any smooth surface that is
within ±5° of true level. The RL-VH3C auto-level
system will not function if the unit is placed more
that 5° out of level. For best operation, it is recommended that it be mounted to a tripod or the Topcon Wall Mount Model 1C (provided).
Slope can be set in both axes, X and Y. See "Setting
Slope" section, page 16.
