CG-2000/CG-1800/CG-1000 Release Notes Updates Always use the most recent firmware version for this unit. For information about the latest firmware, visit the TEAC Global Site (http://teac-global.com/). New functions V1.04 addition o A SCREEN SAVERitem has been added to the Menu Screen UTILITY 1page. This function prevents the occurrence of afterimages on the display during use for long periods of time. NOTE A screen saver function has been added. For details, see "New functions in firmware version 1.04" in the CG-2000/CG-1800/ CG-1000 addendum. Maintenance items V1.08 improvement o Fixed a bug that the end detection display function of video output may be displayed incorrectly. V1.07 improvements o Unlocked judgments are now controlled for reference inputs with large amounts of jitter. This change only affects error display. It has no effect on operation itself. o Video output chasing judgments are now controlled for reference inputs with large amounts of jitter. This change only affects error display. It has no effect on operation itself. V1.06 improvement o Sometimes it would take some time to lock with an external reference signal immediately after starting up. This has been improved (CG-2000/CG-1800 only). V1.05 improvements o If the reference clock setting was changed when it was switching, sometimes locking would not complete. The performance of this function has been improved. o When RED. SEQ.(redundant sequencing) was set to ONE WAY, if both the primary and secondary references were lost, HOLD OVER operation would continue after recovery, but sometimes using PRESET RECALL for primary recovery would not succeed in one operation. The performance of this function has been improved. V1.04 improvements o Sometimes relocking would not occur immediately after starting up during the period when the OCXO was unstable. The performance of this function has been improved. o The activation of the redundant sequencing (RED. SEQ.) setting has been changed from immediately after starting up to after the OCXO stabilizes. o Until the OCXO stabilizes, the unit will operate with preference given to the primary source (PREF.PRI). As a result, the issue of reference clock loss and holdover that sometimes occurred during the period when the OCXO was unstable immediately after starting up (when the INTERNAL SIGNAL LED was blinking) has been resolved. V1.03 improvement o If the reference clock was set to WORD, but the quality of the word reference signal was poor, the LOCK (green) and INFO (blue) indicators would not light after locking sometimes. This has been improved so that they light properly. V1.02 improvements o Even if the unit is turned on when no reference clock is being input, it can now generate synchronized video clock and audio clock (CG-2000/CG-1800 only). o When the AUTO RATEitem on the VIDEO CLOCKscreen is set to ON, the unit will no longer automatically set formats that it does not support (720P/30fps, etc.) (CG-2000/CG-1800 only). V1.01 improvements o If the unit is turned on while the reference clock is set to INTERNAL, WORDor AES, and then redundancy is set to use video and audio reference (WORDor AES), the word clock output signal will stay stable even when switching the reference clock from audio reference to video reference as a result of the redundancy function (CG-2000 only). o If the unit is turned on while the reference clock is set to VIDEObut no video reference signal is being input, when a video reference signal is input later, the amount of time required to lock to it has been reduced (CG-2000 only). o When redundancy is set for video and word reference (WORD or AES), the amount of time required to lock to the video reference signal has been reduced when switching the reference clock from word reference to video reference as a result of the redundancy function (CG-2000 only). o A spelling error has been corrected in the PUSH CANCEL TO CLEARmessage that appears at the bottom of the ERROR INFORMATIONscreen (CANCLE> CANCEL).
