FOREWORD
Thank you for purchasing the TOPCON Auto Tracking Total Station GTS-900A/
GPT-9000A series, Servo Total Station GPT-9000M series.
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 functioning
correctly with normal performance.
Do not aim the instrument directly into the sun
Aiming the instrument directly into the sun can result in serious damage to the eyes. Damage to the
instrument could also result from exposing the instrument’s objective lens to direct sunlight. The use of a
solar filter is suggested to alleviate this problem.
Setting the instrument on a tripod
When mounting the instrument on a tripod, use a wooden tripod when possible.
The vibrations that may occur when using a metallic tripod can effect the measuring precision.
Installing the tribrach
If the tribrach is installed incorrectly, the measuring precision could be effected. Occasionally check the
adjusting screws on the tribrach. Make sure the base fixing lever is locked and the base fixing screws are
tightened.
Guarding the instrument against shocks
When transporting 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 instrument by its handgrip.
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 sudden change of temperature to the instrument or prism may result in a reduction of measuring
distance range, i.e when taking the instrument out from a heated vehicle.
Let instrument acclimate itself to ambient temperature.
Battery level check
Confirm battery level remaining before operating.
Memory back up
The back-up battery built in the instrument needs to be charged approximately 24hrs. before using it for the
first time after purchase. Connect the fully charged battery to the instrument in order to charge the back-up
battery.
Taking the battery out
Leaving the instrument without the battery for more than an hour will cause the memorized data to be lost,
due to low voltage of the back-up battery. Connect the battery as soon as possible or execute RAM back-up.
No responsibility
TOPCON Corporation has no responsibility for loss of data stored in the memory in case unexpected
accidents.
Battery cover
Completely close the battery cover before using the GTS-900A/GPT-9000A/GPT-9000M.If the battery cover
is not completely closed, the GTS-900A/GPT-9000A/GPT-9000M will not operate normally, regardless of
whether the battery or the external power source is used.
If the battery cover is opened while the GTS-900A/GPT-9000A/GPT-9000M is in operation, operation will
automatically be suspended.
Power OFF
When turning off the power, be sure to turn off the GTS-900A/GPT-9000A/GPT-9000M’s power switch.
Do not turn off the power by removing the battery.
Before removing the battery, press the power switch and confirm that the power is off. Then remove the
battery.
While using the external power source, do not turn off the GTS-900A/GPT-9000A/GPT-9000M with the
switch on the external power source.
If the above-mentioned operating procedure is not followed, then, the next time that power is turned on, it will
be necessary to reboot the GTS-900A/GPT-9000A/GPT-9000M.
Maintenance for driving parts
Every 4,000~5,000 hours operation in total, change grease of driving parts.
Contact your dealer or TOPCON Head Office for the maintenance.
External power source
Use only recommended batteries or external power source. Use of batteries or an external power source not
recommended by us may result in equipment failure.
(For further information see Chapter 14 “BATTERY SYSTEM”.)
