T804 DIGITAL VIDEO RECORDER – OPERATING INSTRUCTIONS
The T804 DVR combines the reliability of digital recording with the simplicity of 'VCR
style' controls. Instead of dealing with files and folders, the T804 DVR employs simple
'one-touch recording', 'one-touch playback' and a simple 'time remaining' display.
However, although the controls are as simple as those on a VCR, the T804 DVR never
needs rewinding and there is no possibility of recording over an important survey.
There is no tape, hard disk or delicate DVD to get damaged; all recordings are made on
the Industry-standard Compact Flash Card (CF). The T804 DVR is fully integrated into
the T804 system and was designed specifically for this application.
This Operating Manual contains a 'Quick Start Guide' to get you working quickly and
has separate sections for the most-used functions. Please read the manual fully before
operating your Digital Video Recorder.
