About Hard Disc (HDD)

This Recorder has a built in hard disc (abbreviated “HDD”) for recording and playback. Beware of the following points when setting up and using the Recorder. Failure to observe precautions may cause damage to the HDD itself or its content, failure of the disc to operate, or recording of noise.

•Do not subject to any vibration or impact.

•Do not place at a cramped location which might block the cooling fan or ventilation port on the back of the Re- corder.

•Do not place at a location with severe temperature

variation.

sIf the Recorder is set up at a location with severe temperature variation, dew may form on and inside the Recorder. If the Recorder is used with internal dew formation present, this may cause HDD damage or malfunction. We recommend keeping variation in room temperature within 10˚C per hour.

•Do not place at a location with high humidity.

•Place the Recorder horizontally, never at an incline.

•When the power is on, do not unplug the power cord from the AC outlet, turn off the breaker for the area where the

Recorder is set up, or move the Recorder.

sWhen moving the Recorder, first turn off the power and then unplug the power cord from the AC outlet.

Recording Format

■HDD recording is done using the variable bit rate format for more efficient recording.

The following phenomena may occur.

With the variable bit rate format, the remaining amount which can be recorded may increase or decrease relative to the display of the remaining amount of HDD space.

•When the display indicates that the remaining amount of HDD space is low, first delete unnecessary programmes, and then record with an extra margin in the amount of remaining space.

•Even if you delete a programme, the remaining amount may not increase by the amount of deleted time. When recording new video, record with an extra margin in the amount of remaining space.

•With this Recorder, part of the HDD capacity is used as a system management area.

Unrecordable Material

•This Recorder is equipped with a copy guard function that prevents recording of video software or broadcast programmes that contain a signal that restricts copying in accordance with copyrights and so forth.

•In the case a copy guard signal is contained in a source video that occurs partway through recording, recording is paused at that point. Recording resumes when the copy guard signal is no longer present, while no recordings will be made for the part where the copy prevention signal is present.

In the unlikely event that there is some problem like loss of recorded video or audio content due to a HDD malfunction, please be aware beforehand that Sharp will bear no responsibility to compensate for the content which could not be recorded or edited, for the loss of recorded or edited video, or for other related direct or indirect damages.

■If a power failure occurs

•The content being recorded or timer recorded will be damaged if power failure occurs.

•The content being played back may be damaged.

■For important recording

•If the HDD malfunctions, the content recorded on the HDD may be lost. If you wish to save content perma- nently, we recommend copying or moving the content to DVD-RW or DVD-R.

NOTE

•If a message indicating a HDD error is displayed (such as “CANNOT OPERATE DUE TO HDD ERROR.”) and the HDD has malfunctioned, you cannot replace the HDD by yourself. If you disassemble the Recorder, the warranty will become void. Also, recovery of data is impossible. If playback is possible, re-record the recorded content onto a DVD-RW/R disc, and contact your nearest service centre approved by Sharp.

Hard Disc Operation

(Recording / Playback / Time Shift

Recording)

•If the Recorder is used in a cold location (a location at low temperature), the drive will only allow live viewing after power is turned on until the HDD is ready. During this time, the Recorder will not allow Time Shift Viewing, recording, display of recording lists or playback of recorded programmes. Please wait until the HDD is ready.

Initialization

•Initialization erases all video recorded on the HDD. Be sure to dub important recordings onto DVD-RW/R discs before initializing.

CPRM (control) Information

•There are 3 types of copy control signals: “Copy Freely”, “Copy Once” and “Copy Never”.

“Copy Never” programmes cannot be recorded on HDD. When a “Copy Once” enabled programme is copied from HDD to DVD-RW, the video is not copied — it is moved from the HDD to the DVD-RW (i.e. the content recorded on the HDD is erased).
