User manual ROTEL RC-1550

[. . . ] WARNING: There are no user serviceable parts inside. refer all servicing to qualified service personnel. WARNING: To reduce the risk of fire or electric shock, do not expose the unit to moisture or water. Do not expose the unit to dripping or splashing. [. . . ] Do not connect the power cord to the power outlet until all the audio input and output connections have been made. It is usually best to plug the RC-1550 directly into a 2-pin polarized wall outlet. A heavy duty multi-tap power outlet strip may be used if it (and the wall outlet) is rated to handle the current demanded by the components connected to it. Your RC-1550 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 120 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). the AC line configuration is noted on a decal on the rear panel. Note: Should you move your RC-1550 amplifier to another country, it is possible to reconfigure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RC-1550 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information. If you are going to be away from home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug your amplifier (as well as other audio and video components) while you are away. Like all audio components that handle low-level signals, the RC-1550 can be affected by its environment. Do not stack the RC-1550 on top of a power amplifier. This will minimize chance it will pick up hum or interference. we recommend installing the RC-1550 in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. Be sure to keep the power cords, digital signal cables and regular audio signal cables in your installation away from each other. This will minimize the chance of the regular audio signal cables picking up noise or interference from the power cords or digital cables. Using only high quality, shielded cables will also help to prevent noise or interference from degrading the sound quality of your system. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system. The STANDBY switch 1 is located on the left side of the front panel. to use the RC-1550 , press the STANDBY switch. [. . . ] If it does not light, test the power outlet with another electrical device, such as a lamp. Be sure the power outlet being used is not controlled by a switch that has been turned off. If another electrical device works when plugged into the power outlet, and the Standby Indicator still will not light when the RC-1550 is plugged into the wall outlet, it indicates that the internal power fuse may have blown. If you believe this has happened, contact your authorized Rotel dealer to get the fuse replaced. [. . . ]
