FEATURES
• The detector indicates the presence of CO by a reading on the LCD
and by sounding a beeper.
• Large LCD displays CO levels between 0 and 999 PPM.
• Beeper sounds 3 times continuously between 30-400 PPM.
• Above 400 PPM, the beeper sounds 5 times continuously.
• Bright back-light allows easy screen viewing under dim lighting con-
ditions.
• Battery life indicator (fuel gauge).
• Automatic power off after 10 minutes.
• Max mode stores and displays the maximum CO level taken during
sample time.
• CO level beeper can be silenced if desired.
• Sensor malfunction checking.
• 9V battery is easy to replace.

BATTERY INSTALLATION AND SELF TEST
1. Open the battery door and install the battery
FIG
1.
2. Close the battery door.
3. Turn the detector on by pressing the
ON/OFF
button
FIG
1.
4. The detector beeps twice, then performs a self-test. The dis-
play shows all the icons then shuts them off and counts down
from 9 to 0.
5. Normal display will show the battery life indicator and the
PPM display amount. A small solid dot will flash every 3 sec-
onds showing that the unit is working correctly.
6. The unit will then be ready to automatically detect CO con-
centration levels.
SELF TESTING
1. The detector will self-test each time the
ON
button is pushed.
2. If the battery power is below the level required to power the
detector, the detector will emit a beep and show
Lb
(indicating
low battery) in the display window and the battery icon will show
level or empty bars. This indicates you must replace the battery.
3. If the detector shows
Err
and the sensor malfunction icon
shows on the display, the sensor has been damaged or failed.
See warranty for action.
ESTABLISHING A BASELINE
1. Before testing for CO, the detector establishes a baseline
against which the detector compares other environments.
2. Do this by turning on the detector in a clean environment.
3. If the detector reads between 0-6 PPM, it does not establish
a new baseline, but starts taking CO measurement.
MAXIMUM READING
1. To obtain the maximum reading of CO press the
MAX
button,
the beeper emits one chirp and the
MAX
icon will display in
the top left corner of the display.
2. The reading on the LCD refers to the maximum value, which
has been detected by the unit.
3. After a few seconds the display will restore back to normal
test mode and the
MAX
icon will disappear.
MUTING THE BEEPER
1. To mute the beeper, press the
MAX
button for more than 2
seconds.
2. The mute beeper icon will appear on the bottom left corner of
the LCD.
3. To re-enable the beeper, press the
ON/OFF
button, this will
turn the detector off and then back on.
AUTO BACK LIGHT
1. If the ambient light is too low (making the LCD difficult to
read), the LCD back light will automatically turn on.
2. The back light will automatically turn off when there is suffi-
cient light.
AUTOMATIC POWER OFF
1. The detector will automatically turns off after 10 minutes of
none-use.
