Operational Error Codes

During radio operation, the radio performs dynamic tests to determine if the radio is working properly.
Problems detected during these tests are presented as error codes on the radio's display. The
presence of an error code should prompt a user that a problem exists and that a service technician
should be contacted.

4.6 VHF (136–174 MHz) Band Main Board Troubleshooting
This information will help you troubleshoot the RF section of the VHF (136–174 MHz) band
XTL 1500 radio. Use this information, along with the theory of operation and troubleshooting charts,
to diagnose and isolate the cause of failures.
Prior to troubleshooting, it is important to review the theory of operation, including specific
precautions and troubleshooting methods. Because much of the radio's circuitry operates at high
frequencies, measurements must be taken very carefully. Notes and cautions are added to the text
to alert you to this need in areas of greatest sensitivity. However, the need for extreme care does
exist in all measurements and tests.

Display Flashes "FAIL 001"

This display indicates a synthesizer "out-of-lock" condition. The following information will help to
trouble shoot the frequency generation unit to the component level. Perform the following checks to
determine the mode of the Fail 001:
1. Determine if the "out-of-lock" condition occurs in either receive mode, transmit mode, or both.
Also, check other frequencies programmed in the unit if available.
