Peak Level Reading Feature
The peak level reading is the highest level of CO recorded by the unit until the battery is disconnected. To display the peak level reading
first place your left thumb or finger over the sounder vent, then press and hold the test/reset button down with your right thumb or finger.
The horn will sound and the low-level CO monitor will display the peak level reading stored in the memory until you release the button or for
a maximum of 4 seconds. This feature is helpful to a technician servicing your home or possibly to yourself when returning home after a
period of time and discovering the high or low-level icon displayed on the digital display.
Replacing the battery will cause the peak level reading to reset to 0.
Battery Installation/Replacement
a. If the low-level CO monitor is wall mounted, flip the low-level CO monitor casing down so that the battery compartment is exposed.
b. Remove the battery cover.
c. Replace the battery with an approved 9 volt alkaline battery, making sure the battery terminals align properly with the low-level CO
monitor terminals and push the battery into place. Replace the battery cover and return the low-level CO monitor to the original position.
d. When the battery is connected, your low-level CO monitor will first display all the icons. The digital readout will then display a CAL for
several (5 minutes), and the low-level CO monitor will shortly emit a single beep to indicate that the battery is properly connected. The red
LED will also flash once per minute to indicate that the monitor is receiving power from the battery.
e. Your advanced low-level CO monitor does not require a prolonged ‘power-up’ period. If you have followed all of the above steps
correctly, your unit will begin monitoring for CO in 5 minutes. The circling line is your assurance that your unit is receiving power. If there
are problems with your unit, the digital display will flash “Err” to indicate that there is a problem.
f. Test the unit by pressing the Test/Reset button briefly to confirm that the low-level CO monitor is operating properly. The low-level CO
monitor should sound as soon as the button is pressed, indicating that the horn is working and the battery is providing power to the unit.
Release the test/reset button to silence the horn. The horn and battery should be tested on a weekly basis.
Warning: Prolonged exposure to the horn in close proximity will damage your hearing.
When there is no battery in place, a missing battery indicator will remind you to replace the battery. Under normal operating conditions, the
battery should last 1 year. The battery life in full alarm is 7 days. The low-level CO monitor will not protect against the risk of CO poisoning
when the battery has drained.
Warning: Constant exposure to extreme high or low temperatures may reduce battery life.
