2. Yellow LED Display (800-1200ppm)

3. Red LED Display (>1200ppm & buzzer alarm)

4. Mute Button

5. Power Inlet

6. Housing Stand

7. Screw Position

8. Ventilation Slots

1. 2 min. warm-up time when powering up for the first time.

2. The LCD shows 4 bars with 1sec blank cycle during warm-up

3. The MUTE button is disabled during warm-up

4. The device shows the CO2 reading after warm-up

Press MUTE button to select buzzer on/off. If the “MUTE” function is off, while CO2 concentration exceed the alarm level (>1200 ppm), there will be a buzzer.

Note: The device setting of the alarm is buzzer on when power on first time, user can set the alarm on/off under MUTE function.

Product Overview

Thank you for selecting the RM 100 Room climate monitor. It is a smart, compact and easy-to-use device. In addition to measuring the CO2
concentration, the RM 100 can also measure the ambient temperature and the relative humidity (CO2+Temp. +rH). This product is developed
to help people taking care of the Indoor Air Quality. The RM 100 can be widely used in office buildings, schools, exhibition halls, shopping malls,
meeting rooms, fitness centers, restaurants and other public places where personal comfort and a healthy environment is important.

Features:

 Three different LEDs show the current Indoor Air Quality
 MUTE button for alarm on/off.
 Built-in LCD backlight for easy reading in the dark

Warnings:

 Please take off the AC power adapter and store it well when this CO2 monitor left is idle for

long.

 This CO2 monitor is for home use, not suitable for certifying test results.

EMC/RFI

Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the
performance of the instrument will not be permanently affected.

Note: Within an electromagnetic field of 3V/m, the reading will not meet the specification.
Warm-Up Time: 2 MIN.

3. Do not keep the product under hot and moisture environments. Keep the product away from heat sources or near water.

4. Please use only the included power adaptor. Improper power adaptors or power sources can cause serious damage to the product, or result in injury or death
to the user.

Caring for the product

To ensure you gain the maximum benefit from using this product, please observe the follow guidelines.

1. Cleaning— Disconnect the power before clean. Use a damp cloth, do not use a liquid cleaning agent, such as benzene, thinner or aerosols.

2. Repair— Do not attempt to repair the product or modify the circuitry by yourself. Please contact with the local dealer or a qualified repairman if the product
needs servicing.

3. Air diffusion— The ventilation slots on the housing are designed for CO2 diffusion, so these ventilation slots should not be blocked.
