3. COMPONENTS

3.1. Power Supply

The instrument is powered by either 4 “AA” alkaline batteries or a supplied DC wall

adapter (9V/1A output). Install batteries into the battery compartment on the rear of

the instrument and make sure they are in correct polarity and making good contact.

When the wall adapter is used it will cut off the power supply from the batteries. The

wall adapter cannot

be used as a battery charger.

When battery voltage gets low, “Lob” will appear on the LCD and the audible alarm

sounds. The CO

infrared sensor cannot operate under low voltage, so the instrument

beeps to indicate failed CO

measurement. The user can press any button to stop the

beeps and at that time the sensor readings will not be displayed. To continue, replace

the alkaline batteries with fresh ones or connect the wall adapter.
