ABOUT VOC GASES
VOC gases are invisible to the human eye. They are chemical compounds very often found in building materials, household detergents and bleaches, cigarettes, material additives and adhesives and the like. Here is a brief look at the most common sources of household VOC gases:

Cosmetics

Pesticides

Appliances

Others
POTENTIAL HEALTH HARZARDS
These gases cause pollution to the environment and when breathed in high concentrations over a long period of time, may cause harm to the human body. Here are some of the potential health hazards caused by common VOC gases:
Sources Vinyl tiles VOC Gases Benzyl chloride Affected Organs Central nervous system, liver, kidney, eye and respiratory tract Respiratory tract

SOLUTIONS

As VOC gases are not particles that can be filtered by a household air filter, the best ways to guard against such harmful VOC gases are adequate supply of fresh air, constant ventilation and a good air quality monitor to alert you to the existence of such gases.

BEFORE YOU BEGIN

It does not necessarily reflect the concentration of a particular type of VOC gases. - This unit is designed to response to a wide range of VOC gases. When the [ ] is activated, it does not necessarily mean you are in immediate bodily danger. It means the room needs immediate ventilation. - Always read the instructions of chemicals, materials and appliances used in the household careful. They may contain important information on the pos sible danger or health hazards they may affect when abused.
Paints, solvents, resins and cigarette smokes Paint removers, deodorizers and moth crystals
Benzene and styrene (carcinogens)
Dichloromethane and 1,4Dichlorobenzene (both narcotic)
Central nervous system, liver, kidney, eye and respiratory tract
Polyurethane foam Trichloroethene and aerosols, solvents toluene diisocyanate and cleansing (carcinogens) compounds Adhesives, vinyl Toluene (narcotic) floor covering, wallpaper, tobacco smokes, kerosene heaters Pesticides, varnishes Xylenes (narcotic) and pharmaceuticals

Central nervous system

PRECAUTIONS

POWER REQUIREMENT

The unit comes with a power adapter which should be connected to the unit to provide adequate power for air sampling. To connect the power adapter, plug it into the power adapter connector on the base of the unit before connecting it to a wall socket.
The unit also takes two optional AA-sized batteries. To install the batteries, 1. Remove the battery compartment door. 2. Insert new batteries. 3. Replace the battery compartment door.

NOTE: Do not mix fresh and old batteries, or batteries of differ ent specifications. If operated alone on batteries, the unit will only take temperature and humidity readings. The air sampling function will be disabled. Replace these batteries when the dis play becomes dim.

AIR SAMPLING

Once connected to the power, the AR112N starts to initiate. The whole column on the far right of the bar graph will light up for approximately 10 minutes. Then the unit will sample and display air quality according to the set interval and sensitivity. A normal dynamic display consists of seven columns of the bar graph lighting up one after another. Then the display will freeze for a few seconds and start again. The current temperature and humidity will be displayed at all times. When operated solely on batteries, the unit will not be able to sample air quality. Only the temperature and humidity will be shown and the botton row bar graph will flash.

HOW TO INSTALL THE UNIT

The AR112N Air Quality Monitor is designed to sample and determine the level of VOC gases in the room that it monitors. This unit is for indoor use only. As most VOC gases enter the human body through breathing, it is recommended you mount or place it at eye level of the user using the recessed mounting hole or retractable table stand. For instance, if the unit is to be installed in the living room, it should be installed at the eye level of a standing adult. If the unit is to be used in the kids room, it should be installed at the eye level of the kid sitting on the bed.

HOW TO READ AIR QUALITY

The air quality is displayed on the bar graph and rated very good, good or bad. An indicator will light up to show what the air quality is.

Very Good

You can select to display the average air quality in three intervals: 70 seconds, 7 hours or 7 days. To do so, press MODE repeatedly. When the 7-hour or 7-day interval is selected, the 0 column means the current hour or day and each column to its left means a previous hour or day, respectively. When the 70-second interval is selected,
the current 10 seconds are on the column on the far right. Each column to its left means 10 previous seconds.

TEMPERATURE AND HUMIDITY

The current temperature and humidity are displayed at all times. To show the maximum or minimum readings in memory, press [ ] or [ ], respectively. Press the button again to go back to the current readings. The unit will also do so automatically after 5 seonds. To clear the memory,press and hold C button for two seconds.
HOW TO ADJUST SENSITIVITY LEVEL
The sensitivity level affects how the unit rates the air quality. You may have to adjust the sensitivity according to the actual environment of the installation or specific needs. To adjust the sensitivity level, 1. Press [ 2. Use [ ]. The [ ] or [ ] indicator will blink. ] to select the desired level.

C/F SWITCH

The temperature unit is selected on the C/F switch. Slide the switch to C for degree Centigrade or F for degree Fahrenheit. The selected unit will apply to the current temperature as well as temperatures in memory.
3. Press [ ] to exit. The unit will also return to normal display after 10 seconds. Note that the new sensitivity level only applies to future samplings but not the old ones in memory.

HOW TO USE THE BACKLIGHT

Press [ ] to turn on the backlight for five seconds.

BAD AIR WARNING

When the air quality is considered bad, the [ ] indicator will appear to show the room needs immediate ventilation. These indicators will remain lit until the air quality improves. If the ALARM ON/OFF switch is set on ON, an alarm will also go off continuously for 10 seconds. If the air quality does not improve, a beep will be emitted every minute for the next 7 minutes and every 10 minutes afterward. To stop the alarm, press any button. To disable the feature, set the switch to OFF.

THE RESET BUTTON

This button is used only when the unit is operating in an unfavorable way. Use a blunt stylus to hold down the button. All memories will be erased.
