2Check that the image received on the TV monitor is correct.

3Check that the on-screen display of the date and time is correct.

4To check the recording condition of the previous day, rewind the recorded tape a few seconds.

5Press the PLAY button and check that the playback image is correct.

6Check that the recorded date and time are correct.

NOTES:

œIf the security lock is engaged, it has to be released before proceeding to the inspection.

œIf any problem is discovered during the inspection, unplug the power cord then consult your dealer.

Periodic Inspection

Periodic inspection and maintenance should be referred to your dealer.

If the playback picture is not clear, and it cannot be corrected using the tracking control, it may indicated that the video heads need cleaning.

The video heads should be inspected every 1,000 hours of use to determine if they need to be replaced.

The video heads usage can be checked using the (POWER/DEW/USED TIME) menu.

Cabinet Cleaning

Clean the outside of the cabinet with a clean, soft cloth, moistened with lukewarm water and wrung dry.

DO NOT USE SOLVENTS OR OTHER TYPES OF CLEANERS. THESE CHEMICALS CAN CRACK OR DISCOLOR THE CABINET.

About the Backup Lithium Battery

The date and time settings are maintained for up to 30 days by a rechargeable lithium battery that is fully charged after the VCR has been connected to a power source for 48 hours or more.

Depending on the battery usage it may become necessary to change it. For replacement and disposal of the old battery, please contact your dealer.

After the battery has been replaced, press the ALL RESET button, then enter all the time, date, etc. settings as required.
