• Character searches can only be performed during stop, pause, and playback modes.
• The unit will fast forward or rewind until it finds the character string, then shift into still frame mode.
• If the unit does not find the character string, it will stop automatically.
• When there are multiple instances of the same character string, repeat character search if the retrieved image is not the
desired image.
• Character searches may be time-consuming as the process involves searching through all the data.
• Forward searching is the only option available when using a DDS device for playback.
