User manual ROTEL RA-1062

[. . . ] 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 allow foreign objects to get into the enclosure. [. . . ] For example, to change the volume level, you can either turn the control on the front panel or use the buttons on the remote. When only one identifier appears, that control is available only on the front panel or the remote, but not both. Two UM-4/AAA size batteries (supplied) must be installed before the remote control can be used. To install the batteries, remove the cover on the back of the RR-AT94. install the batteries as shown in the illustration in the battery well. Test the control for proper operation, then replace the cover. When the batteries become weak the remote control won't operate the RA-1062 consistently. Installing fresh batteries should eliminate the problem. NOTE: Remove the batteries from the remote if it will not be used for a long period of time. Do not leave run down batteries in the remote control; they can leak corrosive chemicals which will damage the unit. The size and quality of the wire can have an audible effect on the performance of the system. Standard speaker wire will work, but can result in lower output or diminished bass response, particularly over longer distances. in general , heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. Your authorized Rotel dealer can help in the selection of cables for your system. 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. The polarity ­ the positive/negative orientation of the connections ­ for every speaker and amplifier connection must be consistent so all the speakers will be in phase. if the polarity of one connection is reversed , bass output will be very weak and stereo imaging degraded. All wire is marked so you can identify the two conductors. there may be ribs or a stripe on the insulation of one conductor. The wire may have clear insulation with different color conductors (copper and silver). Turn off all the components in the system before connecting the speakers. [. . . ] Each setting provides a fixed frequency contour as follows: OFF: the tone contour circuits are bypassed to ensure the purest possible sound. Press the button again to return the sound volume to the original level. The LED in the volume control will flash when the unit is muted. The PHONES output allows you to connect headphones for private listening. [. . . ]
