Receivers
Receivers are powered by two AAA alkaline batteries
that last for at least forty hours of continuous opera-
tion with the backlight turned off and twenty hours with
the backlight on. The Receiver has two user controls
and a backlit LCD display so the user can choose and
view options and status information. The user controls
are momentary pushbutton switches. A LIGHT button
toggles the LED backlight on and off, and a MODE but-
ton turns power on and off and moves through all the
user options.
Figure 2 shows the LCD display with all icons turned on. There are five rows of icons
with the top four rows arranged into six columns. Each column represents one associ-
ated Sensor if it has been programmed. The icons have the following meaning:
ALARM icons come on for five seconds after a motion message is received
from the associated Sensor.
SIGNAL icons indicate that the Sensors are in range. Since Sensors send a
message once per minute and remain on for one minute each time a message
is received, the SIGNAL icon will remain on for as long as the Receiver is within com-
munication range of the Sensor. Note that when power is turned on it may take up to
one minute for any SIGNAL icon to appear.
