Adcom GTP-740 - Manual (Page 9)

Shift (8-14) button; This allows each of the 7 tuner preset buttons to do “double duty.” When the
LED in the center of the shift button is illuminated red, the 7 tuner preset buttons activate tuner
presets 8-14. When the LED in the center of the shift button is not illuminated, the 7 tuner preset
buttons activate tuner presets 1-7.
FM/AM button; As you might expect, this button selects AM or FM. In addition to the selected
broadcast frequency, a small “AM” or “FM" indicator appears in the bottom of the Display Window
to confirm your choice.
10 Seek/Manual button: This controls the tuner’s scan function.
In Seek mode (indicated by the word “seek” in the bottom center of the Display window), the tuner
will automatically go to the next active broadcast frequency when you press either of the Tuning
buttons (see #11 immediately below.)
In Manual mode, the tuner will jump to the next higher or next \ower adjacent frequency when you
press either Tuning button, whether or not that frequency is active. For example, if the GTP-740
indicates an FM frequency of 91.1 (MHz) and you press the Tuner Up button, the GTP-740 will
display 91.3, the next available frequency. Similarly, if you’re listening to an AM broadcast at
1630 (kHz) and press the Tuning Down button, you will see 1620.
Note: These frequency intervals apply only to North America. Other countries may be different.
11 Tuning DownAJp buttons: These allow easy selection of all the stations your GTP-740 can
receive. Remember that these Tuning buttons will scan to the next active or to the adjacent
frequency depending on how you’ve set the Seek/Manual button described above.
12 Panel Dim button; This reduces Display window brightness for listening or viewing in a dark
room. The button simply toggles between full and reduced illumination.
13 Audio Mute button; This button lowers levels at the main preamplifier outputs by 20 dB. Press
It again to restore previous levels. Audio Mute does not affect “Room 2” outputs.
14 input Selector buttons and LED indicators: These allow easy dioice of any available input.
When you select a particular input, the LED in the center of that button will light and the input
name will appear in the Display window to confirm your choice. Choosing an input automatically
selects the Surround mode last used with that input. You may change frie Surround mode at any
time by using the Surround Mode button (#3 above.)
15 Master Volume control; This rotary knob raises the volume to all active speakers
simultaneously as you turn it clockwise and lowers volume when you turn it counter-clockwise.
16 IR (infrared) sensor: This small window receives invisible infrared commands from the remote
controller. Do not block this window with accessories, cables, CD jewelboxes, etc., or the
remote controller will not work.
17 Room 2 button; Pressing this button will activate the Room 2 output circuitry, enabling any of six
analog audio and video sources; LD, VCR, video aux, CD, tape, and tuner. Pressing the
Room 2 button will cause the LED’s on the available source buttons to illuminate. The source that
is currently selected for room 2 will be flashing. Choose the source you want to send to Room 2
by pressing the desired source button, it wili illuminate steadily and the others will go off.
