-
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 at the point which they exit from the product.
-
Protective Attachment Plug: The product may be equipped with an attachment plug with overload protection. This is a safety feature. See the operating instructions for replacement or directions to reset the protective device. If replacement of the plug is required, be sure the service technician has used a replacement plug that has the same overload protection as the original plug as specified by the manufacturer.
-
Outdoor Antenna Grounding: If an outside antenna is connected to the product, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANS/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 (see figure).

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

USB CONNECTIONS
Minimum PC Requirements
You can connect the MP-C546 to a computer with a USB port to transfer files to your player or to manage the files on your player. The minimum requirements listed below will allow you to perform basic file management functions; advanced features will require a faster PC and Windows configuration.
MS Windows 98SE (Service Pack 1) or ME [USB-MSC];
MS Windows 2000 (Service Pack 3 or above) with Windows Media Player 9 [USB-MSC];
MS Windows XP (Service Pack 1 or above) with Windows Media Player 10 or newer [USB-MTP]

USB 1.0 port (a USB 2.0 Hi-Speed port will enable file transfers up to 40 times faster).
New versions of Windows Media Player may be downloaded from the Microsoft website at www.microsoft.com.
USB CONNECTIONS
USB Driver Installation (Windows 98SE Only)
It is not necessary to install the USB driver if your computer is running Microsoft Windows ME/2000/XP or newer, or Macintosh OS X. Computers running these operating systems will recognize your player automatically when connected.
If your computer is running Windows 98 SE, please download and install the driver from the COBY website: www.cobyusa.com.
USB Mode (MSC/MTP)
The MP-C546 can use either USB-Mass Storage Class (USB-MSC) mode or USB-Media Transfer Protocol (USB-MTP) mode to connect to your computer. Both USB modes allow for simple, high-speed transfers of files between your player and a computer, and allow you to use your computer's operating system to view, manage, and transfer files to your player from your computer
There are, however, a few differences to take note of.
USB CONNECTIONS
| USB-MSC USB-MTP | |
| Simple plug-and-play support for all major operating systems (Microsoft Windows 98SE/ME/2000, Macintosh OS X, Linux) | Simple plug-and-play support for Microsoft Windows XP with Service Pack 1 and Windows Media Player 10 (or newer) |
| Supports Windows Media DRM 9 | Supports Windows Media DRM 9 (WMDRM9) |

| -- Windows Media Playlist support | |
| USB 2.0 Hi-Speed file transfers USB 2.0 Hi-Speed file transfers | |
| Database rebuild required after each USB connection. | Database rebuild not required. |
In general, USB-MSC mode enjoys wider compatibility with different computers and operating systems, while USB-MTP mode enables advanced features (e.g., playlist synchronization), but requires Windows XP SP1 and Windows Media Player 10 or newer.

To transfer and synchronize encrypted WMDRM10 files, USB-MTP mode (in conjunction with Windows XP and Windows Media Player 10) is required. Most online music stores and subscription services use WMDRM10 files*. Please refer to the documentation of either Microsoft or the store from which you purchased your music for more information and support.
