DV-HR300U 1. IMPORTANT SERVICE NOTES This Unit is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the rear cover. This product contains a low power laser device. To ensure continued safety do not remove any cover or attempt to gain access to the inside of the product. Refer all servicing to qualified personnel. Note: This unit can be used only where the power supply is AC 110V-240V, 50/60Hz. It cannot be used elsewhere.
DV-HR300U IMPORTANT SERVICE NOTES etc.) and measure the AC voltage drop across the resistor. Reverse the AC plug on the set and repeat AC voltage measurements for each exposed part. Any reading of 0.45V rms (this corresponds to 0.3mA rms AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the VCR/DVD combination model to the owner.
DV-HR300U NOTES DE SERVICE IMPORTANTES pièces métalliques exposées ayant un parcours de retour au châssis (connexions d’antenne, coffret métallique, tétes de vis, boutons et arbres de commande, etc.) et mesurer la chute de tension CA entre la résistance. Inverser la fiche CA (une fiche intermédiaire non polarisée doit être utilisée à seule fin de faire ces vérifications.) sur l’appareil et répéter les mesures de tension CA pour chaque piéce métallique exposée.
DV-HR300U Precautions for using lead-free solder 1 Employing lead-free solder "Operation (R) PWB, Operation (L) PWB, Power PWB and UV PWB" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder. Example: LFa Indicates lead-free solder of tin, silver and copper.
DV-HR300U 2. FEATURES z A new timer recording system:"Easy Recording Guide" » The Recorder is equipped with a high-capacity hard disc, so you'll have more chances than ever before for timer recording, and the new timer recording system makes this even easier. A schedule grid of times and channels is displayed on the screen, and by simply designating cells in the grid with the remote control, timer programming becomes as easy as circling your favorite shows in the newspaper.
DV-HR300U 4 Batch erasing of titles/chapters Titles and chapters which become unnecessary after editing can be batch erased by selecting them from the list of recordings (thumbnails). 5 Edit undo function*4 If you mistakenly erase data during editing, this function lets you restore it to its immediately preceding state, just like "Undo" on a PC, so you can edit worry-free. *4 Edit undo can only be used once. It only works when "DELETEDIT" is assigned to a colored button (green) displayed on the screen.
