IMPORTANT PRODUCT SAFETY INSTRUCTIONS

Electrical energy can perform many useful functions. But improper use can result in potential electrical shock or fire hazards. This product has been engineered and manufactured to assure your personal safety. In order not to defeat the built-in safeguards, observe the following basic rules for its installation, use and servicing.

ATTENTION:

Follow and obey all warnings and instructions marked on your product and its operating instruc- tions. For your safety, please read all the safety and operating instructions before you operate this product and keep this manual for future reference.

INSTALLATION

1. Grounding or Polarization

(A)Your product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature.

If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.

(B)Your product may be equipped with a 3-wire grounding-type plug, a plug having a third (ground- ing) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature.

If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.

2. Power Sources

Operate your product only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. If your product is intended to operate from battery power, or other sources, refer to the operating instructions.

3. Overloading

Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of fire or electric shock.

4. Power Cord Protection

Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product.

ANTENNA INSTALLATION

INSTRUCTIONS

1. Outdoor Antenna Grounding

If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

2. Lightning

For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges.

3. Power Lines

An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

GR-DVL100 specifications

The JVC GR-DVL300 and GR-DVL100 are part of JVC's line of compact and versatile MiniDV camcorders that gained popularity in the early 2000s. Both models are designed to cater to the needs of amateur videographers and provide high-quality video recording in a user-friendly format.

The JVC GR-DVL300 stands out with its progressive scan technology, which enhances video clarity and reduces motion blur. This feature is particularly beneficial when shooting fast-moving subjects, making it a great choice for capturing sports events or action-packed scenes. The GR-DVL300 also boasts a 20x optical zoom lens, which allows users to get closer to their subjects without sacrificing image quality, while a digital zoom feature extends this capability even further.

In contrast, the GR-DVL100 is equipped with a 16x optical zoom and offers slightly fewer advanced features compared to its sibling. However, it remains a robust option for those who prioritize simplicity and ease of use. Both camcorders incorporate JVC’s advanced Image Stabilization technology, reducing camera shake and ensuring smooth footage, even during handheld use.

A key characteristic of both models is their ability to record in both LP (long play) and SP (standard play) modes, providing flexibility in recording time and video quality. Users can choose the mode that best suits their needs, whether they want longer recording durations or superior video quality.

Additionally, both camcorders feature a built-in digital still camera function, allowing users to capture snapshots at 640x480 resolution. This dual functionality adds value for those who want to capture both video and still images without the need for separate devices.

The JVC GR-DVL300 and GR-DVL100 also come with an array of connectivity options, including USB ports for easy transfer of videos to computers as well as S-Video and AV outputs for playback on larger screens. Their compact design makes them portable and convenient for on-the-go shooting, catering to travelers and event documentarians alike.

With their blend of functionality, ease of use, and versatile features, the JVC GR-DVL300 and GR-DVL100 remain noteworthy options for casual filmmakers who want reliable performance and impressive video quality in a compact camcorder package.
