2AZUG-GGMMR3Wireless Transmitter

1 GGMMR3 Wireless sensor 1 Temperature display 2 Symbol for radio frequency connection between base unit and wireless sensor (display only appears when the transmission is occurring), and Current 2 transmission channel 3 Low battery indicator 4 Red pilot light 5 Humidity display 6 Sliding switch 1 2 3: Set sensor number (transmission channel) 7 Temperature switch button: °C/°F 8 switch button: TX 9 Battery compartment 10 Loop for hanging 1. Remove the battery compartment cover on the front of the wireless sensor. 2. Insert 2 LR6 (AA) / 1.5 V batteries (not included) facing in the direction indicated on the bottom of the battery compartment. Make sure that the poles of the batteries are correct (+/-). As soon as the wireless sensor is receiving power, the red pilot light will light up and thus display that data is being transmitted to the base unit. 3 3. Put the battery compartment cover back in place. - Do not use batteries that have a voltage that is too low (only 1.2 V instead of 1.5 V). This affects the accuracy of the measurements, among other things. - If possible, use alkaline batteries instead of zinc-carbon batteries. Alkaline batteries last longer, particularly outside in low temperatures. 4.FCC STATEMENT 1）. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. 2）. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to 4 provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/ TV technician for help.

MPE ESTIMATION FCC ID: 2AZUG-GGMMR3 1. Limit for Portable Equipment Exposure Frequency 1-g SAR 100MHz-6GHz 3.0 For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz 2. Estimation Result Frequency (MHz) PK Output Power(dBm) Output Power(mW) Test Separation Distance (mm) Measurement Result 1-g SAR 433.92 -21.97 0.006 5 0.001 3.0 Note: 1. use the maximum E-field strength(75.38dBuV/m) for the RF exposure evaluation 2. E(dBuV/m)=EIRP(dBm)-95.2 for distance 3m so the EIRP=75.38dBuV/m-95.2=-19.82dBm 3. EIRP(dBm)= ERP+2.15dBi so the ERP=-19.82dBm-2.15dBi=-21.97dBm ------The End------
