PREP ARA TIONS 38 Battery Operation (Cont’d) Precautions for the Battery Opera- tion • Do not detach the battery pack while recording is taking place.
39 PREP ARA TIONS FOR OPERA TION T urning the Power ON T urning the Power ON 1. Set the POWER switch to ON. This device turns on in Camera mode. The operation differs according to whether this device is in the Camera mode or in the VTR mode. The mode switches each time you press the CAM/VTR button.
PREP ARA TIONS FOR OPERA TION 40 Loading/Unloading the Cassette Cassette Loading Use a videocassette tape marked MiniDV . • T o record, slide the switch on the back for use in prevent- ing accidental erasure to the “REC” side. • Remove any the tape slack before loadi ng.
41 Setting and Displaying the Date and T ime The date and time of the built -in clock should be set. Pow- ered by the built-in backup battery the set date an d time data continue to count even when the power is switched off.
PREP ARA TIONS FOR OPERA TION 42 Setting and Displaying the Date and Time (Cont’d) Setting the Date and Time 1. Display the CLOCK ADJUST menu screen. Select the CLOCK ADJUST item on the TIME/DA TE menu screen. 2. Set the date and time. The blinking digit is the one to be set.
43 Displaying T ime Code The GY -HD25 0/GY -HD251 reco rds SMPTE-standard (NTSC) or EBU-standard (P AL) time codes and user ’s bits. In the play mode or the record mode, the reproduced time codes or user ’s bits are shown on the LCD monitor or in the viewfinder .
