To compensate for this difference, the mode called drop mode drops frame 00 and 01 for every minute that cannot be divided by 10. The non-drop frame mode is when no frames are dropped and the actual time shift is neglected. Note: When the VCR Setup Menu item No. 398 SSF MODE is set to CUE MODE or MARK MODE, the time code generator's running method is internally set to the REGEN mode. When this is the case and you want to enter the preset mode, set the VCR Setup Menu item No. 398 SSF MODE to "OFF", or set the PRESET/REGEN switch to the PRESET position again. Ⅲ Setting the time code related switches • Set the PRESET/REGEN switch to "PRESET". • Set the REC/FREE switch. REC : The data preset in the time code generator runs only during recording. Use this setting if it is required to record continual time codes across different scenes. * However, approximately ±1-frame variations may occur in scene transition accuracy. FREE : The time code starts to run from the time it is preset in the time code generator. Ⅲ Setting the VCR Setup Menu • Set the VCR Setup Menu item No. 516 DISPLAY SELECT to "TC". Select the time code generator's framing mode using the VCR Setup Menu item No. 416 NON DROP/DROP. DROP : The time code generator's running method is set to the drop frame mode. Use this setting when placing emphasis on the recording time. The "DF" indicator lights up on the display in the drop-frame mode. NON DROP : The time code generator's running method is set to the non drop frame mode. Use this setting when placing emphasis on the number of frames. In the NON DROP frame mode, the "NDF" indicator lights on the display. NDF H M S F 56
