FOREWORD
Thank you for purchasing the TOPCON Digital Theodolite. For the best performance of the instruments, please carefully read these instructions and
keep them in a convenient location for future reference.

General Handling Precautions
Before starting work or operation, be sure to check that the instrument is
functi onin g correctly w i th normal perf ormance.
Do not submerge the instrument into water.
The instrument can not be submerged underwater.
The instrument is designed based on the International S tanda rd IP66,
therefore it is protected from the normal rainfall.
Setting the instrument on a tripod
When mounti n g the i ns tru me nt on a tripod , use a wooden tri pod when po ssible. The vibr ations th at may occur when usi ng a metallic tripod can effect the
measuring precision.
Installing the tribrach
If the tribrach is installed incorrectly, the me asuring precisi on could be
effe cted . Occasionall y chec k the adjust ing scr ews on the tribrac h. Make sure
the base fix in g lever is locked and the base f ixin g screws are tightened.
Guarding the instrument against shocks
When transpor ting the instrument, provide some protection to minimize risk
of shocks. Heavy shocks may cause the measurement to be faulty.
Carrying the instrument
Always carry the instrum ent by its handgr ip.
Exposing the instrument to extreme heat.
Do not leave the instrument in extreme heat for longer than necessary.
It could adversely affect its performance.
Sudden changes of temperature
Any sud den chang e of temper atu re to the instrument or pris m may resu lt i n a
reduction of measuring distance range, i.e when taking the instrument out
from a heated vehicle. Let instrument acclimate itself to ambient temperature. When a high degree of precision is required for measurement, provide
shade against direct sunlight for the instrument and tripod.
Battery level check
Confirm bat t ery le vel re maining before opera t ing.
Store with the batteries removed, when operation is halted for more than a
month. Leav i ng the batteries att a che d for ext e nded period of time can res ult
in battery leakage, which may lead to malfunctioning.
2
Notice on Transceiver
When using high out put transceiver etc. , make sure it does not come near
the instrument.
Opening the carrying case
When opening the carrying case and taking out the instrument, place the
case ho riz ontally, then open the case.

•Batt ery can cau se ex pl o sion or inj u ry.
Do not dispose in fire or heat.
•Risk of fire or electric shock.
Do not use any po wer v o ltage except th e one given on manufacturers instructions.
•Batt ery can cause outb reak of fire.
Do not block up the vent of the bat tery.
•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.
Do not connect or disconnect equipment with wet hands , you are at
risk of electric shocks if you do!
Risk of injury by overturn the carrying case.
Do not stand or sit on the carrying cases.
Please note that the t ips of tripod can be hazardous , be a ware of th is
when setting up or carrying the tripod.
Risk of injury by falling down the instrument or case.
Do not use a carrying case with a damaged which belts, grips or
latches.
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.
A plumb bob can cause an injury to a person if used incorrectly.
It could be dang erous if the instrument falls over, please ensure you
attach a handle to the instrument securely.
Ensure that y ou mount the Tribrac h correctly, f aili ng to do so may re-
sult in injury if the tribrach were to fall over.
It could be dangerous if the instrument falls over, please check that
you fix the instrument to the tripod correctly.
Risk of injury by falling down a tripod and an instrument.
