LCD BLINKING BACKLIGHT
When working in the menus, should the backlight
begin blinking, it means that there is an alarm
message. You can exit to the top level (Banner
Message Display) and read the message or just clear
the blinking backlight.
This is how to clear the blinking backlight: From
the Banner Message Display, press the right arrow,
then press the down arrow three times. The display
will read Clear Latched Alarm. Press the
EXEcute key and the blinking will stop. To return
to the top menu, press the up arrow until the
Banner Message Display appears.
Another way to clear the display is through the
Commands Facility Main Menu by selecting
option 9, Clear Alarm Displays.

EYPAD RESET
The Multiserver can be manually reset from the
keypad by pressing the two outside keys at the same
time and holding them for two seconds. This is a
hardware reset (warm start), and the current
configuration will remain unchanged, except for
the time and date. The time and date are lost
during this reset. (A warm reset accessed through
the LCD/Keypad Administration Menu does not
erase the date and time.) This reset does not
require a password.
Within the Administration Menu of the LCD, there
are four reset options: warm start (current
configuration), cold start (default configuration),
link reset, and channel reset. These four reset
options can be protected with a keyboard password
(see Section 11.5, Network Security).
LCD/K
EYPAD PASSWORD PROTECTION
The LCD/keypad password protects all the
administrative, diagnostic, and configuration
functions, allowing access only to review the alarm
and status messages in the system message log.
The password may be a series of up to eight up,
down, left, and right arrows, followed by the
EXEcute key. This sequence is entered in the
Command Facility as U, D, L, R characters followed
by a <cr>. For example, after configuring
UUDL<cr> as the password, you would enter 2 up
arrows, a down arrow, a left arrow and EXEcute at
the LCD/Keypad password prompt. Do not use
commas when configuring. If no password is
required, enter a space during the password
configuration.
The default configuration is for no password. If you
wish to configure a password, see Section 11.5,
Network Security, for more information.
The following LCD/keypad functions are not
password-protected:
• Review system messages log function
• Banner message display
• Hardware reset.
T
IMEOUTS
• Backlight Timeout. The LCD backlight will
remain lit for five minutes. After that time, if
there is no keypad activity, the light will go out.
To relight the display, press any key of the
keypad.
• Menu Timeout. There is a five-minute timeout
feature on the menus. If there is no activity on
the keypad within a five-minute period, the
system will time out and return to the Banner
Message Display.
NOTE: There is one exception. When the
LCD is in a monitoring mode (during
a diagnostic test), the menu will not
time out.
• Event and Alarm Messages Display Timeout.
Current event and alarm messages will be
displayed at the Banner Message Display as long
as there is activity at the keypad. If there is no
keypad activity for two minutes, the message will
time out and no longer be displayed at the LCD.
The messages in the system log queue will not
time out; the queue will always display the most
current ten messages.
