Foreword
Thank you for purchasing the Topcon RL-VH4G Rotating Laser.
It is one the world’s most advanced lasers.
To quickly and effectively use the RL-VH4G, please read these brief instructions carefully, and keep them in a convenient location for future reference.
Handling Precautions
Before starting work or operation, be sure to check that the system is functioning properly.
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.
3. Checking battery power.
Before operating, check remaining battery life.
4. Storing the instrument for long period
When storing the instrument for long period, remove the batteries.
5. Rotating Head
When sunlight, etc. enters the laser emitting window, laser beam output may temporarily
decrease. In such a case, prevent sunlight, etc. from entering by using a parasol or other
means.

Display Meaning
WARNING
Ignoring or disregard of this display may lead to death or serious
injury.
CAUTION
Ignoring or disregard of this display may lead to personal injury or
physical damage to the instrument.

Safety Cautions
WARNING
• There is a risk of fire, electric shock or physical harm if you 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. (RL-VH4G standard model)
Do not stare into beam or view directly with optical instruments. (RL-VH4G remote control compatible model)
• 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.
4
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 awareness 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.

Preparation for Use
Battery Installation
For battery placement or replacement instructions, see Maintaining Power Sources section,
page 20.
Instrument Set-up Procedure
Horizontal Rotation
1
Set the instrument on any smooth surface that is
within ±5° of true level. The RL-VH4G 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 .
Slope can be set in both axes, X and Y. See "Setting Slope" section, page 20.
Horizontal
Leveling range
12
Ver tical Rotation
1
Place the instrument on its back as shown in the illustration.
2
Tu rn the leveling screw (s) underneath the instrument until the
bubble in the level vial on the operational panel is centered.
Battery Warning Lamp
Flashing : The power is low
ON Solid: Dead batteries
Replace the batteries with new ones.
Auto-leveling Lamp
Flashing : Auto-leveling is in process. When automatic leveling is almost complete, the
flashing rate will be slow. The head will not rotate and the laser beam will not
emit during the auto-leveling process.
ON Solid: Auto-leveling is complete.
The rotary head is active and emits the laser beam.
Turn ing Auto-leveling Off
To turn OFF the auto-leveling function (manual mode), press the Auto/Manual control pad
twice in quick succession. The manual mode indicator light will illuminate. The instrument
can be positioned in any direction, the laser beam remains on and the head will rotate.
IMPORTANT:
In manual mode, the laser beam will not shut off if disturbed! To return to Auto-leveling mode,
press Auto/Manual control pad once.
13
Operation
Scanning Mode
In scan mode, the laser rotates slowly, "searching" for the Magnetic Scanning Target. When
the target is properly placed in the beam path, the laser beam will scan rapidly back and forth
on the target and "track" the target as it is moved in its path.
1
To change to scanning mode when operating, press the Mode Control Pad (see page 10).
2
To initiate target scanning, place the Magnetic Scanning Target in the beam path with the
reflective strips facing toward the laser.
3
To end target scanning and resume searching beam, remove target from beam path.
Vertical rotation
Horizontal rotation
Set scanning mode
Face the target toward the instrument to start scanning.
