1 NOMENCLATURE AND FUNCTIONS
• Laser Pointer ON/ON(blink)/OFF (GPT-7500)
The laser pointer assists with collimation by radiating visible laser light from the objective lens to the
target. The laser pointer can be used for the Prism, Non-prism and Non-prism long mode.
• Non-prism mode / prism mode
To switch the non-prism / prism mode, press the Non-prism / prism switching icon.
For more information, see Chapter 3.2 “Distance Measurement”.
•
The laser pointer indicates the approximate collimation position of the telescope. It does
not indicate the exact collimation position.
•
When the EDM is working, the laser pointer will blink.
•
You cannot see the laser pointer when looking through the telescope. Therefore, please
look directly, with the naked eye, at the point indicated by the laser pointer.
•
The distance to which the laser pointer can be used will vary with climatic conditions and
with the eyesight of the user.
•
When the laser pointer is used, the operating time of internal power source will become
short.
•
When the GPT-7500 is used in the open air, in an urban area, etc., the laser pointer can be
stopped and distance measurement then conducted, making it possible to prevent the
laser light from hitting a third party.
•
Use the operation keys on the telescope eyepiece side for key operation. If you use the
operation keys on the objective lens side, an error will be displayed and the laser pointer
will not turn on. This prevents the laser beam from hitting the eyes of the operator.
