18ENGLISHAbout the DHT-T100 Control Button LEDsThe eight LEDs illuminating the top panel control buttons flash or light in various patterns to indicate different functions.Power Momentarily bright when DHT-T100 is turning on/waking from sleep; steadily dim while on/awake(operating mode); steadily dark when DHT-T100 is “asleep” in standby mode; flashes whentoggling between manual- and auto-on/standby modes.Television Input Momentarily bright when Television Input is selected, whether manually or automatically byactive signal at any wired input.Bluetooth® Input Flashes bright, rapidly, while Bluetooth is “pairing” a wireless device; steadily brightwhen selected.The Bluetooth LED will flash bright, slowly, while attempting to re-pair a device that has passed out of range orotherwise lost wireless contact, and blink rapidly to indicate a Bluetooth error (unable to pair). This will cease after 60seconds or if any DHT-T100 key is pressed.Learning Flashes when learning functions from your remote (see "Use Any Remote to Control your DHT-T100"on page 20).Listening Mode Flashes once when pressed at the front panel, and selects the next Listening Mode (see"Listening Modes" below).Mute Flashes bright continuously as long as Mute function is invoked.Listening ModesDHT-T100 includes five Listening Modes for different kinds of audio programs, room acoustics, or personal preferences. It alsohas a special “Night Mode,” which enhances low-volume listening, which is described in the following section.Select a Listening Mode using either Listening Mode key (front panel or remote). Each keypress advances in sequencethrough the five modes – Dialog, Music, Music Wide, Movie, and Movie Wide. DHT-T100’s front panel key LEDs momen-tarily display a pattern representing each newly selected mode. The following information describes the various listeningmodes, and shows an illustration of the LED pattern displayed when that mode is selected.Note: The LED displays used to indicate the various Listening Modes are simple horizontal display patterns—there is noc orrespondence between the lit LEDs and their underlying key functions.Dialog mode highlights center-recordedsounds such as movie dialog, televisionannouncers, or musical soloists; it is valuable for everyday television viewing. The Remote Learning and Listening Mode LEDslight to indicate the Dialog mode is selected.Music mode produces conventional stereosound. The Bluetooth and Mute LEDs light toindicate the Music mode is selected.Music Wide mode widens the “soundstage”somewhat for a more enveloping, involvingsound. The four buttons indicated show whenit is selected.
