7.0 OPERATING THE UNIT
The LM-1520R and LM-1920R monitors are operated using front panel controls and an
On Screen Display (OSD). The controls consist of a group of six buttons located on the
lower center of the front panel. Please refer to illustration below and the discussion that
follows.
Power Switch: Pressing the button labeled ‘POWER’ will cause the LED at the extreme
right of the control panel to change color from Red to Green and power will be applied
to the monitor’s circuitry. Pressing the button again will cause the LED to glow with a
Red color and the power will be removed from the monitor’s circuitry.
Source Switch: Pressing the button labeled ‘SOURCE’ will step the inputs through all
possible signal input selections. Repeatedly press the button until you arrive at the
desired input.
Auto Switch: Pressing the button labeled ‘AUTO’ will cause the monitor to optimize the
picture any time a VGA source is present and selected. This function is only used when
VGA video is the selected signal.
Menu Switch: Pressing the ‘MENU’ button will cause the OSD menus to appear. When
an OSD Menu is active, the two adjust buttons become the controls for selecting
individual functions on the OSD and also are used to adjust functions once they are
selected.
Operationally, the Menu button is pressed and a menu item is selected by using the
Adjust switches (arrow keys) to move a cursor until it is over the desired menu item.
Once the cursor is over the menu item you want, pressing the Menu button again
selects the item. The adjust buttons are then used to make an adjustment or turn a
function on or off as appropriate.
There are several menus to choose from but the method of accessing and changing
menu items is always the same: Press the Menu button to begin the selection process,
move the cursor using the adjust buttons, press the menu button again to select the
desired activity or sub menu. Once you are at the desired menu item, use the adjust

10
buttons to make the adjustment. When you are through making adjustments, press the
menu key again and move the cursor to the Exit selection. Press the menu button to
select ‘Exit’.
Adjust Switches: Adjust Switches (Adjust Buttons) are used to set the audio volume
level anytime the OSD is inactive. When the Menu button is pressed, the adjust buttons
function as described above.
7.1 Menu Structure
There are four sub-menus that are used to make adjustments to the monitor via the On
Screen Display (OSD) should monitor performance need improvement.
Pressing the Menu button begins the selection process. Move the cursor using the
adjust buttons and then press the menu button to select the desired sub-menu. Once in
the sub-menu, use the adjust buttons to move to the desired activity and press the
Menu button again to select the individual function you wish to change. Use the adjust
buttons to actually make the change. When you are through making adjustments, press
the menu key again to save the adjustment. Move back to the main menu and to
another sub-menu via the Adjust buttons. After a period of time determined by the OSD
Timeout parameter in the System Sub-menu, the OSD display will disappear.

properly, the picture will be unclear. Therefore this value should be
carefully adjusted.

the pixel clock across one line at a time. Therefore it can affect the
picture position and size.
Note: improper adjustment will cause image failure.

8.0 TROUBLESHOOTING
The major cause of difficulty with the LM-1520R and LM-1920R monitors is use of faulty
or low quality cables, attempting to use cables over to long a distance and selecting the
wrong source for what is actually connected to the monitor.
A second problem is misadjusting the monitor through improper use of the various setup
menus. Before contacting TV One’s technical support personnel, please make certain
that your problem is not due to one of the above issues.
After trying the above suggestions should the problem still persist, contact your dealer
for additional suggestions before contacting TV One. Should the dealer’s technical
personnel be unable to assist you, contact TV One via our support website:
http://tvone.crmdesk.com. Create a technical support request on the site and our
support team will respond within a short period of time.
