NOMENCLATURE AND FUNCTIONS
Manual mode ON (Red LED)
Auto leveling does not function.
Height alert OFF (Red LED)
Height alert does not function.
Height alert OFF switch
OFF:Push twice continuously.
ON:Push once.
Manual mode ON switch
ON:Push twice continuously.
OFF:Push once.
Handle
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
instrument from operating if it is
disturbed. This insures accurate
control. If the unit is disturbed, all
lamps will blink except battery
power lamp. The elevation
(height of instrument) should be
verified and re-established if
necessary. This function is not
active in the manual mode.
HOW TO OPERATE
1
• Set the instrument to the tripod or smooth surface.
• Make sure instrument is roughly level (±3°).
• Press power switch (ON).
EXAMPLES OF TYPICAL USE

CAUTION
• Use of controls or adjustment or performance of procedures other than those specified
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.
Beam aperture
Power switch
The power switch turns ON or OFF by pressing.
On-Grade precision switch
Two on-grade precision options are available, normal
precision (±2mm) and high precision (±1mm). By pressing
this switch, the precision options are switched alternately.
Confirm the precision choice by the indicator. (Normal
precision is the default setting each time the sensor is turned
on. See LS-80A/80B Indicator diagram below.)
Beam receiving window
Turn the beam receiving window side towards RL-H3C to
detect the laser beam.
Indicator
Detect the on-grade position "---" by moving the level 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 level sensor is 40mm (1 9/16")
from on-grade index for offset marking.)
The indicators are located on front and back sides of the
instrument.
LS-80A:The indicators are located on front and back sides of
the instrument.
LS-80B:The indicator is located only on front side.
Buzzer sound switch
Volume of the sensor buzzer can be alternately switched to
LOW/LOUD/OFF by pressing the switch.
Auto-cut off function
The power will be turned off automatically if no laser beam is
detected for approximately 30 minutes. (To turn on the level
sensor, press the power switch again.)
