RF Wireless Air Quality Sensor Model: 001A21 USER’S MANUAL Congratulations on your purchasing this New Air Quality Sensor. This unique product was designed for everyday use at home or office and it is a definite asset of great use. To fully benefit from all the features and understand the correct operation of this product, please read this manual thoroughly. MAIN FEATURES DESCRIPTION OF BUTTONS A. RED LED INDICATOR: blinks when RF transmitting. B. [MODE] BUTTON C. BATTERY DOOR D. STAND E. AC/DC ADAPTOR SOCKET F. [RESET] BUTTON G. SENSOR COVER (for cleaning) H. SENSOR LENS Functions of the wireless Air Quality sensor This Air Quality sensor is a precision instrument that displays Air Quality Index (which help to understand what local air quality means to health, and the table below shows the detailed information), color indicator, health level and comfortable face icon. And the device transmits the data continuously to the receiving unit to bring you the latest information. This product adopts wireless 433 MHz technology, which can transmit data at the maximum distance of 30 meters (100 feet) in an open area. Power supply The user can select battery supply (just for spare use), and/or the special adaptor for continuous power supply. For battery installation: 1. First pull the stand out of the device, and remove the battery door. 2. And then insert 4 AAA size batteries according to “+”, “-” polarity marks inside the battery compartment. 3. Close the battery door and install the stand To enable the continuous power supply: 1. First plug the adaptor into the socket at the bottom side of the device. 2. Plug the power adaptor into the electrical socket. Getting Started At power on, LCD full display for 3 seconds. Then the remote sensor will automatically transmit registration codes to the receiving unit, together with LED indicator blinking and the ) ) ) icon flashing. And the face icon, color indicator, AQI, and health level will be displayed on the LCD of the sensor unit. If the transmission is sucessful, the display of the receiving unit will show a new channel number, AQI, face icon, and color indicator. If not, you can also press and hold “MODE” button for 2 seconds to send the signal manually to the receiving unit. Installation of the Air Quality Sensor Locating the remote sensor in an open area can attain a maximum 30-meter transmission distance. Actual transmission distance can be reduced by interference from building, obstruction or a screen between the remote sensor and the receiving unit. The user can use the stand to enable the horizontal surface mounting. Note: In order to get good air convection, the front panel of the device should be cleared of obstructions. To reset the device The RESET button allows you to return all settings to factory set values. The button is required only when the device is not operating in a good way, such as in rare case of malfunction. Slide to open the battery door of the device, and use a pointer to press the RESET button. The device will be reset and all data will initiate with default values. Sensor cover In normal operation, the user cannot slide open the cover and doing so will have bad effects on the testing values. If the device operates with the lower sensitivity, please slide open the cover, and clean the lens with a clean swab and ethyl (denatured) alcohol. Do not use rubbing alcohol. Generally, the user just needs to clean the lens once a year. Battery replacement The device is equipped with the low battery detection.
