Thank you for purchasing the TOPCON RL-H3CS Rotating Laser.
The RL-H3CS instrument has many unique features. For basic operation, rough level the instrument and press power switch. It
will self-level, then emit a rotating laser beam to create a level reference plane. The laser provides controls that allow the beam
plane to be tilted up to 5 degrees for single slope applications.
For superior product performance, please read these instructions carefully and keep them in a convenient place for future reference.
GENERAL HANDLING PRECAUTIONS
Before star ting work or operation, be sure to check that the instr ument is functioning correctly with nor mal performance.
When storing the instrum ent for long period, remove the batteries.
Always make sure instrument is dr y before putting it in the carrying case. Never store a damp instrument.

WARNING
Ignoring or disregard of this display may
lead to the danger of death or serious inju-
ry.
CAUTION
Ignoring or disregard of this display may
lead to personal injury or physical damage.
CAUTION
• Use of controls or adjustment or performance of procedures other than those spec-
ified herein may result in hazardous radiation exposure.
• Do not stand or sit on the carrying cases.
It could overturn, causing injury.
• Do not use a damaged instrument case.
It could accidentally open causing damage to the instrument or injury to people.
• Do not place yourself or a reflecting object in the path of the laser beam. If using the
laser outside, avoid positioning it anywhere near eye level to avoid any possibility of
it striking someone in the eye. If this should happen, visibility could be temporarily
impaired, causing disorientation and possible accidental injury.
• Please note that the tips of tripod can be hazardous, be aware of this when setting
up or carrying the tripod.
• 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.
• Do not place instrument on unstable platform, surface or tripod.
If using tripod, make sure instrument is securely attached.
• Risk of injury by falling down a tripod and an instrument.
Always check that the screws of tripod are tightened.

Detect the on-grade position “---” by moving the Laser Sensor
up and down. Directional arrows and audio signals assist in
locating the on-grade position as the laser strikes the beam
receiving window. (Top of Laser Sensor is 40mm (1 9/16")
from on-grade index for offset marking.)
LS-70B:The indicators are located on front and back sides of the
instrument.
Indicator
On-Grade precision switch
Two on-grade precision options are available, normal preci-
sion and high precision. By pressing this switch, the preci-
sion options are switched alternately . Confirm the precision
choice by the indicator. (Normal precision is the default set-
ting each time the sensor is turned on. See LS-70B Indica-
tor diagram below.)
The power switch turns ON or OFF by pressing. If the power
switch is turned ON, all signs will be displayed on the indica-
tor for a second with a beep sound.
Volume of the sensor buzzer can be alternately switched to
LOW/LOUD/OFF by pressing the switch.
Auto shut off function
The power will be turned off automatically if no laser beam
is detected for approximately 30 minutes. (To turn on the
laser sensor, press the power switch again.)

Height alert function
(Safety lock system)
When auto-leveling and height
alert function are active, after the
laser beam emits for one minute,
this function prevents the instru-
ment from operating if it is dis-
turbed. This insures accurate
control. If the unit is disturbed,
manual mode ON lamp, height
alert OFF lamp and auto leveling
lamp will blink simultaneously. The
elevation (height of instrument)
should be verified and re-estab-
lished if necessary. This function
is not active in the manual mode.

Remove the battery cover by turning battery cover knob to “OPEN” side.
2
Remove the batteries by pulling out the slide plate.
3
Install the new batteries referring to the illustration on the battery
cover.*1, *2, *3
4
Install the battery cover. By using a coin, tighten the battery cover knob
to “CLOSE” side until the knob does not turn.*4
*1 Replace all 4 batteries with new o n es at t he same time. Do not mi x used and new batteries,
and do not mix different types of batteries together.
*2 Use alkaline dry c ells. (Dry cells for movement confirmation are packed in s hipment.)
Nickel hydrogen dry c ells and nickel cadmium dry cells c an be used too, but the operating time
is different from the time of alkaline dry cells.
*3 Generally, performanc es of dry cell deteriorate temporarily in low temperature, but recover in
normal temperature.
*4 It is important to use a coin or other tool to make sure cover is firmly closed to seal out water.
