1 STANDBY SWITCH: Pressing this key, or the HTR 2 remote’s [ON] button, will switch the receiver on, making it operational, changing the amber
Standby indicator to green and illuminating the VFL display.
2 STANDBY LED: Illuminates amber when the T 743 is in Standby mode; green when it is powered on; and flashes momentarily to indicate infrared
commands received from the HTR 2 remote. Protection Mode is indicated by a red illumination, and indicates that there is a problem with your set-
up or the unit itself. When the fault is removed, normal operation can be resumed (this may require turning the unit off and on again). This indicator
will be steadily dark only when the main POWER switch (REAR PANEL No.10) is switched off (or the receiver is unplugged from the AC supply).
3 AM/FM: Press to toggle between the tuner’s AM and FM bands.
4 DISPLAY: Press to display the channel mode of the currently selected source (other than the internal AM/FM tuner), in the format “front/rear/LFE.”
For example, a Dolby Digital or DTS 5.1-channel source will display 3/2.1. Note that the display shows signal channels, not speakers; for example,
a 2-channel analog or digital source (whether stereo or surround-encoded) will show 2/0.0, even though the receiver’s <Speaker Settings> may
indeed be set up to use the subwoofer with all sources, and the current Listening Mode may employ center and surround speakers.
When the AM/FM tuner is the selected input, sequentially pressing DISPLAY shows the currently tuned station’s RDS data, toggling between the
current station’s Radio Text and Station Name displays (see Listening to Radio, below).
5 MEMORY: Use to store tuned stations to the T 743’s 40 preset-memory locations. (see Listening to Radio, below)
6 FM MUTE/MODE: In the normal Mute position, only the stations with a strong signal can be listened to, and the noise between stations is muted.
Pressing the [FM Mute/Mode] button allows distant (and potentially noisy) stations to be received. (See “Listening to Radio”)
7 PRESET
: Press to step up or down between radio presets; 30 FM and 10 AM station presets are available. Note that this function “wraps”:
Pressing
will step from Preset 30 to Preset 1, or vice versa using thekey. “Unused” presets are skipped over. (Note that Presets must previously
have been stored; see “Listening to Radio,” below.)
8 SEARCH
: Press momentarily to step up or down between FM or AM frequencies. Press and hold SEARCHfor more than 2 seconds to
search up or down; the T 743’s tuner will stop at the next sufficiently strong signal it encounters. Note that this function, too, “wraps,” and will
continue searching up or down from one end of the AM or FM band to the other.
Note that: SEARCH
tunes the FM band by 0.05 MHz steps (twice the precision of most tuners and receivers). On the AM band, SEARCH
moves by 10 kHz or 9 kHz steps. To change the step amount, hold in the FM MUTE/MODE and AM/FM keys simultaneously.
9 VFL DISPLAY: The Vacuum Fluorescent Display provides visual information on all of the T 743’s important modes, settings, and functions for both
MAIN and second ZONE locations.
10 VOLUME (SETUP): Turn clockwise to increase the master-volume setting; counterclockwise to lower it. The VFL and on-screen displays show the
setting, displayed in decibels between –74 and +18.
The VOLUME (SETUP) knob is also used to increment/decrement individual channel levels and other adjustable parameters.
