F e a t u res and Operation of Digital Display Model
(continued)
Other Possible Displays and Their Meanings
The following symbols will appear on the display during
normal or error operations, and are explained below.
Normal Operation
Normal operation (see figure 3) with a full b a t t e ry.
The dot in the lower right corner cycles on and off
every 5 seconds. If CO is present the display will
indicate the reading in Parts Per Million (PPM).
Normal Operation following Power-up or Reset
Figure 4 shows the normal display immediately
after installing batteries or after the test/reset
button is pressed. The display should change to the
normal display (see figure 3) approximately
30 seconds after pressing the test/reset button.
(see Test/Reset Button page 13).
If the test/reset button is pressed, the alarm will sound. The display
will show a number during the time that the alarm is sounding.
This number is a normal part of the test function, and does
not indicate a CO reading.
Peak Level Display
When the peak level button is pressed and held,
the display shows the highest CO reading taken
by the CO alarm since its last peak level reset or
power-up(Example shown in Figure 5). The
backlight will illuminate for several seconds after
the peak level button is pressed to help see the
reading.
Although the peak level feature will display levels below 30 PPM,
these levels will not result in an alarm no matter how long the
device is exposed to these levels.

Features and Operation of Digital Display Model
Your new Kidde Battery Powered CO Alarm utilizes sophisticated
electronic components to protect you and your family from the
dangers of CO.
Unique features include a digital display capable of displaying CO
concentrations in (PPM) Parts Per Million and the highest levels
of CO detected. Familiarize yourself with these features:
Digital Display Backlight Feature
To help see the displayed reading in the dark, a backlight appears
when the peak level button is pressed.
Digital Display - Shows CO level in PPM
Your Kidde CO alarm continuously displays a digital readout of
the CO level in Parts Per Million (PPM). The digital display is
capable of detecting and displaying readings between 30 and 999
( P P M ) .
A reading of 0 PPM is expected under
normal conditions
(see figure 2).
You will become accustomed to glancing at the
display in much the same manner as you look at a thermometer
or clock. The unit will not automatically display reading below 30
PPM. However, readings between 11 and 999 PPM will be stored
in the Peak Level Memory.
