EN If the LCD displays “-.-”, press and hold the CH button to rescan for the signal. · Press "CH" button to query CH2, CH3 data or cyclic display, When the symbol appears, it means that the data of three channels will be displayed circularly. 1 2 Query Maximum/minimum numerical value · When the indoor / outdoor temperature and humidity are shown in the LCD, the product began to record temperature and humidity maximum and minimum numerical value. · Press once MEM button, the LCD will display maximum value of temperature and humidity. The LCD will display the minimum value of temperature and humidity if you press once MEM button again when the maximum value is displayed. · At the same time, there are "MAX" or "MIN" displayed on the LCD. · The arrow in the lower right corner of the screen indicates the maximum and minimum outdoor temperature: The symbol indicates the maximum temperature The symbol indicates the minimum temperature · The temperature and humidity maximum/minimum value will RE records after press and hold MEM button 2 seconds, at the same time, there will be "- -.-" displayed in the LCD 2 second. · The memory value of the day will be automatically cleared at 0:00 every night. F.Y.I.: · If the temperature reading is below ranges, the LL.L will be displayed. If the temperature reading is above ranges, the HH.H will be displayed. EN MAX MIN Comfort level The temperature of the remote sensor is below 20°C(68°F); The temperature of the remote sensor is Between20°C (68°F) and 30°C (86°F); The temperature of the remote sensor is above 30°C(86°F). Low battery indicate When the symbol of low batteryappears in the INDOOR, it means that the RX needs to be replaced with new batteries. When the symbol of low batteryappears in the OUTDOOR, it means that the remote sensor needs to be replaced with new batteries. FCC Caution: This device complies with part 15 of the FCC Rules. Operation is subject to the following two cond…

Page 1 of 3 RF EXPOSURE EVALUATION FCC ID: 2BRMO-TX15 Product Name : Outdoor Sensor Model Name : TX15 Operating frequency : 433.922MHz Numbers of Channel : 1channels for SRD Antenna Type : Spring antenna Antenna Gain : 0dBi Type of Modulation : ASK Power supply : DC 3V Hardware Version : N/A Software Version : N/A Page 2 of 3 Standard Requirement According to § 15.231 and § 1.1307b(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See KDB 447498 D01 General RF Exposure Guidance v06, section 4. 3. 1. The 1-g and 10-g SAR test exclusion thresholds for 100MHz to 6GHz at test separation distances ≤ 50mm are determined by: [ (max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]*[ √f(GHz)] ≤3.0 for 1-g SAR and ≤7.5 for 10-g SAR extremity SAR, where ⚫ f(GHz) is the RF channel transmit frequency in GHz ⚫ Power and distance are rounded to the nearest mW and mm before calculation ⚫ The result is rounded to one decimal place for comparison. The test exclusions are applicable only when the minimum test separation distance is ≤ 50mm and for transmission frequencies between 100MHz and 6GHz. When the minimum test separation distance is <5mm, a distance of 5mm is applied to determine SAR test exclusion. Routine SAR evaluation refers to that specifically required by § 2.1093, using measurements or computer simulation. When routine SAR evaluation is not required, portable transmitters with output power greater than the applicable low threshold require SAR evaluation to quality for TCB approval. RF Output power Freq. (MHz) Field strength(max)(dBuV/m) EIRP (max) (dBm) 433.922 79.08 -16.12 Note: EIRP=E-104.8+20logD, Where E is the electric field strength in dBμV/m. EIRP is the equivalent isotropically radiated power in dBm. d is the specified measurement distance in m. where D=3, EIRP=E-95.2.
