TROUBLESHOOTING
Before the system tests are started, the
Table 8 is intended as an aid in localizing trouble. If trouble is encountered with the operation of the D3LX, verify that all installer connections are correct and that the options are configured properly. If technical assistance is required, refer to “Appendix C - Product Support” on page 41. ADC strongly recommends that no internal (component level) repairs be attempted on the module. The only field service should be a fuse or module replacement. Any unauthorized adjustments or repairs may void the unit’s warranty.
