Справочник Пользователя для IBM 1483

The 1483 is designed to operate with a color SVGA or VGA, or a monochrome SVGA or
VGA monitor. If the screen is not displaying correctly, or there is interference from
nearby electronic devices, you may need to change the vertical refresh rate (color) or
mode/intensity setting (monochrome) on your monitor. Follow the appropriate
procedure below.

If you use a color monitor, two vertical refresh rates are possible, 72 Hz mode (the
default) and 60 Hz mode.

To change the vertical refresh rate, turn the Power-On/Off switch to Off, then press and
hold one of the following function keys while you turn the Power-On/Off switch to On:

F1 – Sets a color monitor to 60 Hz vertical refresh rate.

F2 – Sets a color monitor to 72 Hz vertical refresh rate.

F7 – For multifrequency monitors that can operate up to 42 KHz, sets vertical refresh
rate to 75 Hz.

To adjust the mode or intensity setup, turn the Power-On/Off switch to Off, then press
and hold one of the following function keys while you turn the Power-On/Off switch to
On:

F3 – Sets the monitor to 14-inch monochrome VGA mode with “color” menus that display
varying monochrome intensities in different fields.

F4 – Sets the monitor to 14-inch monochrome VGA mode with “color” menus that display
varying monochrome intensities. This setting gives a different set of intensity defaults
than those generated by pressing F3.

F5 – Sets the monitor to 15-inch SVGA mode.

F6 – Sets the monitor to 14-inch or 15-inch monochrome with overscan (for use with
monitors that support overscan).
