Keyboard Polling
4.36 For proper operation of the console a visually impaired atten-
dant must be aware of the status of the keyboard. For example,
he/she must know whether the BELL OFF or NIGHT 1 button has been
enabled. To do this the attendant presses the LAMP TEST button in the
silent mode (the ringer is off, the 7-segment indicators are on and the
LEDs are off). While this button is held depressed, the remaining rel-
evant buttons are pressed in turn. If the LED associated with a button
is lit, the ringer will sound as long as the button is pressed down. If
the LED is flashing, the ringer will give a 0.5 second on, 0.5 second off
audible signal. In this manner the status of the BELL OFF, NIGHT 1 or
any button (including an incoming call) can be determined and appro-
priate action taken. When this operation takes place, the LAMP TEST
button is the last to be released; otherwise the current button being
polled will become active when the LAMP TEST is released first.

5.04 GUEST ROOM: This button is used to give a number of facili-

display information about a hotel room and to give room occupants
additional facilities (or restrictions). These features are summarized as
follows:
(a) The display of the status of each room can be given in respect
to whether it is occupied (rented) or vacant, and whether it is
clean or requires cleaning. In addition, the display indicates I'
whether the maid is in the room. This display is accomplished
by pressing the GUEST ROOM button and dialing the room
