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 instru-
ment from operating if it is dis-
turbed. 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).

* LS-70B is included for some markets instead of LS-70C.
• 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.

(1 9/16") 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/70C
Indicator diagram below.)
