Troubleshooting
This chapter will help you diagnose and solve some common problems that may occur with the receiver.
Check This First!
Before contacting your local dealer or Sokkia Technical Support, check the following:
•
Check all external receiver connections carefully to ensure correct and secure connections. Double check for
worn or defective cables.
•
Check the receiver’s internal batteries for a full charge.
•
Check the power source for incorrectly connected cables, and ensure the power source is valid. See
“Specifications” on page 43 for external power requirements.
•
Check the software. Make sure the most current software version is downloaded onto the computer and the most
current firmware is loaded into the receiver. Check the Sokkia website for the latest updates.
•
Check Sokkia Technical Support (www.sokkiasupport.com) for the latest updates.
Then, try the following:
•
Power on and off the receiver by pressing the Power button or by using SRU (Tools
Reset receiver).
•
Restore default settings by clearing the NVRAM. See “Performing a Factory Reset” on page 30. This restores the
receiver’s parameters to the factory default settings and erases the almanac and ephemeris files. This action
does not delete data files from the receiver memory.
If the problem persists, see the following sections for other solutions.
Powering Problems
The following are some of the most commonly encountered power problems.
The receiver does not power up
•
The battery may be discharged.
– Charge the battery overnight. See “Charging the Batteries” on page 16.
•
If you are using an external power source, the cable may be disconnected or damaged.
– Make sure the cable is securely connected and undamaged.
•
The receiver may have a defective charger or defective battery.
– If, after changing the battery or connecting an external power source, the receiver still does not power
up, contact your local dealer or Sokkia Technical Support for advice.
Do not attempt to repair equipment yourself. Doing so will void the warranty and may damage the
hardware.
