Radar system configuration is saving to non-volatile memory at fixed intervals.8.4.5.1 About the Battery AlarmIf is appeared at the lower-right of the display when start up the radar system, the battery has not enough time left to live. We recommend to replace the battery.If is appeared at the lower-right of the display when start up the radar system, the battery has no time left to live. There is a necessary to replace the battery. In This condition, this radar system is restored configuration information from flash memory and normal operation is available. However, you turned of the radar system before saving to flash memory, the configuration information is maybe lost. In this case, you must setup the configuration again.8.4.5.2 How to Replacement of Backup Battery[Required tools]•A flat tip screwdriver for 6 mm screws•A Phillips screwdriver for 4 mm screws•A flat tip nonconductive screwdriver for 3 mm screwsReplacement of backup battery must be made by specializedservice personnel.
