This can be additional information such as the presenter's or program's name; what song is playing, etc. This text scrolls continuously over the 8 alphanumeric display segments. It takes a few seconds for the tuner to gather the RT information, so immediately after tuning to a station and selecting to view RT the display will indicate "WAIT" and default to the station name. c) Press the button from the display RT mode to display the station frequency.

With each successive tap of the keys, the tuner will take 0. 05 MHz steps on FM so you can accurately tune into the desired frequency. For AM the tuning steps can be 9 kHz or 10 kHz, depending on the version of your T770. This tuning mode can also be useful when trying to receive a radio station which is too weak for the auto search mode. When tuned accurately to a station, " TUNED " will light up in the display. With stations carrying RDS information, the station's RDS name is displayed, Program Service (PS; normally the station's calling letters, BBC R3, for instance). Refer to the separate chapter "Storing, recalling and naming Presets" for more information. NOTE: The 120V versions (North America) do not have RDS (Radio Data System). FM MUTE/MODE This button combines two functions; it switches the tuner from Stereo to Mono and disengages the muting circuitry at the same time. The muting circuit will mute the tuner in between radio stations when searching or tuning. Very weak radio station signals however may be suppressed by the muting circuit. If such a very weak station is in stereo it will have a high level of background hiss. Switching to Mono Mode and disengaging the muting circuit by depressing the FM MUTE/MODE button will allow the station to be heard and will cancel most or all of this background noise. In normal operation the mute circuit is engaged, the display indicates "FM MUTE". Press the FM Mute/Mode button to disengage the muting circuit and switch from stereo to mono reception. "FM MUTE" will extinguish in the display. Also, "STEREO" will extinguish if a stereo broadcast was received. [. . . ] The Level settings are stored in the T770's memory. They are automatically recalled when the unit is switched on. Depending on the software played back on the T770 is may sometimes be desirable to make minor adjustments to the level of the Center, Surround speaker or subwoofer. Instead of through the OSD Speaker Setup procedure it is also possible to access Level Calibration direct: · Make sure the volume is set to a normal listening level. [. . . ]
