User manual ROTEL RA-1070

[. . . ] Do not place objects filled with liquids, such as vases, on the unit. Do not allow foreign objects to get into the enclosure. If the unit is exposed to moisture, or a foreign object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit to a qualified service person for inspection and necessary repairs. [. . . ] The PLAY, STOP, PAUSE, TRACK and RANDOM buttons, and NUMERIC keys (0-10) operate many Rotel CD players after the CD button on the remote has been pressed. Like all audio components that handle low-level signals, the RA-1070 can be affected by its environment. This will minimize the chance it will pick up hum or interference. This programming only needs to be done once: The speaker outputs are controlled by the switch on the front panel. It must be unobstructed or the remote control will not work properly. The operation of the remote sensor can also be affected if it is exposed to bright sunlight or certain types of lighting (such as halogen lights) that emit infrared light. In addition remote control functions may not work reliably if the batteries in the RR-AT94 are weak. If only one set of speakers will be used at any given time, the speakers may have an impedance as low as 4 ohms. If there are times when both the A and B speakers will be used, all the speakers should have an impedance of 8 ohms or more. Speaker impedance ratings are less than precise. In practice, very few loudspeakers will present any problems for the RA-1070. Note: The IR signals from the EXT IN jack can be relayed to source components using external IR emitters or hard-wired connections from the IR OUT jacks. Turn off all the components in the system before connecting the speakers. the RA-1070 has color-coded speaker connectors on the back panel. These connectors accept bare wire, or connector lugs. Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using dual banana plugs, connect them to the wires and then plug into the backs of the binding posts. If the turntable has a "ground" wire connect it to the screw terminal to the left of the Phono inputs. Because of its relatively high power rating, the RA-1070 can draw considerable current. Therefore, it should be plugged 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 RA-1070 and all the other components connected to it. Your RA-1070 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60Hz AC or CE: 230 volts/50 Hz AC). [. . . ] If you are unable to get sound from the RA-1070 refer to the suggestions for the following conditions: Should you need to reset the IR code, press the MUTE button A on the RR-AT94 remote control for more than 5 seconds while pointing it at the RA-1070. The unit will return to default condition and the Listening CD LED q will turn on to indicate the IR code is reset. Contact your authorized Rotel dealer for further information. The power indicator ring around the power button should be lit whenever the RA-1070 is plugged into the wall power outlet and the POWER switch is pushed in. [. . . ]
