Front Panel / Buttons

OPERATION

FRONT PANEL

The layout of the BH100 is a very simplistic design. The black piano-like finish can be easily cleaned
with the cloth supplied with the unit. With the lack of a true front bezel, all of the backlit buttons
are contained on the top panel. The POWER button (Œ) is a physical button located on the left side.
The remainder of the buttons, OPEN/CLOSE (•), PLAY/PAUSE (•), STOP (•), and RESOLUTION (•), are
touch-sensitive and located on the right side of the unit. As with most all LG – Zenith DVD Players,
that do not include a VCR, the Disc Tray (‘) is center-mounted. The IR Receiver (’) and Display Panel
(“) are located on the right side of the front.

Powering on the unit will cause the POWER button and LG Logo to light up, followed by the remainder
of the buttons lighting up from left-to-right. The Display Panel will scroll “PLEASE WAIT” while the
unit is powering up. In about 30 seconds from the initial power request, the unit will be fully booted.
After approximately another 10 seconds the backlights for the buttons will turn off, leaving the LG
Logo on as a power-on indicator.

NOTE: The control buttons are touch-sensitive and must not be pressed with force. A light touch

by a finger is all that is required to activate the button. Using objects other than human
fingers, such as pointing devices, discs, etc, may not activate the button(s) or cause
undesirable results.

TIP: By default, a slight chime, or beep sound, is played when a button is activated to alert the user
that the button request has been received. This can be disabled within the User Menu.

TIP: The control buttons can be disabled using the LOCK command from the Remote Control. When
the LOCK function is activated, “LOCK ON” will be shown on the Display Panel anytime a control
button is pressed on the unit. Simply pressing the LOCK button on the Remote Control will turn this
function on or off.
