EW780-1410-00Baby Monitor - Baby Unit

Note • This baby monitor is intended as an aid. It is not a substitute for proper adult supervision, and should not be used as such. Test your baby monitor You may test the baby monitor before initial use, and at regular times thereafter. Caution • For hearing protection, make sure the parent unit is more than 6.5 feet (2 meters) away from the baby unit. If you hear any high-pitched noise, move the parent unit further until the noise stops. You can also press on the parent unit to lower or mute the noise. 1. Make sure your baby unit and parent unit are on. 2. Speak towards the microphone of the baby unit. You will hear the sound at the parent unit, and see the visual sound indicators light up. Note • When the POWER/LINK LED light flashes, move the parent unit closer to the baby unit (observe the minimum distance of 6.5 feet / 2 meters). You can also check if the baby monitor is connected to a live power socket and switched on. Tip • Increase the speaker volume of the parent unit if you cannot hear the sounds transmitted from the baby units. Positioning the baby monitor Caution • Keep the baby unit out of the reach of your baby. Never place or mount the baby unit inside the baby’s crib or playpen. Note • To avoid interference from other electronic devices, place your baby monitor far away from devices such as wireless routers, microwaves, cell phones and computers. 1. Place the baby units more than 3 feet (1 meter) away from your baby. 2. Place the parent unit more than 6.5 feet (2 meters) away from the baby unit to avoid screeching noise. Caution • The default volume of your parent unit is Level 3, and the maximum volume is level 5. If you experience high-pitched screeching noise from your baby monitor while positioning: -Make sure your baby units and parent unit are more than 6.5 feet (2 meter) apart, OR -Turn down the volume of your parent unit. Operating range The operating range of the baby monitor is up to 1,500 feet (450 meters) outdoors or 160 feet (50 meters) indoors. The actual operating range may vary depending on the environmental conditions and other interferences such as walls, doors and other obstructions.

INTERTEK TESTING SERVICES FCC ID: EW780-1410-00 RF exposure - 1 of 1 For Maximum Permissible Exposure (MPE) evaluation of the baby unit, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65 and meet the requirement listed in KDB447498. For the 1.9GHz Baby Unit of tested model: DM1111 BU, the measured powers among all the measured channels were within its production tolerance: +16 dBm (Minimum) and +21 dBm (Maximum).The antenna gain of DM1111 BU is 0 dBi = 1.00 (num gain) and its maximum source-based time-averaging duty factor is 12.5% (3/24 x100%). From these data and its operating configuration – Mobile device, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The Conducted Power = 21 dBm = 125.9 mW The Conducted Power source-based time-averaging output power = (125.9 * 0.125) mW = 15.74 mW The power density at 20cm = 15.74 *1.00/ 4πR 2 = 0.0031 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the baby unit at least 20cm from nearby persons.”
