RD8200SG model features an internal clock which is used to time and date survey measurements, the 1/second internal logging and for the CALSafe feature.

Every time the locator is switched on, it performs a check to verify its correct operation.

In the unlikely event of an issue with this clock the system will emit a warning audio tone and display the word ERROR, followed by a 3-digit error code.

Make a note of this code and contact your nearest service center or Radiodetection representative.
