EW780-8180-00AAudio Baby Monitor - Baby Unit

Install the parent unit batteryThe parent unit runs on rechargeable battery or AC power. To continuously monitor your baby, make sure you use both battery and AC power at the same time. With the battery alone, the parent unit can cordlessly run for a short time only. NOTESNOTE • Use only the battery supplied with this product.• If the parent unit will not be used for a long ti me, disconnect and remove the battery to prevent po ssible leakage. Replace the battery To replace the battery, unplug the battery connector from the socket, and then pull the battery out of the battery compartment. Follow the steps above to install the battery. Connect the baby monitor NOTESNOTE • Use only the power adapters supplied with this product.• Make sure the baby monitor is not connected to an electric outlet that is cont rolled by a switch. • The power adapters’ prongs are not designed to hol d the weight of your baby monitor. Make sure you connect the adapters to wall outlets that are in vertical or floor mount position. Do not connect them to undermount and ceiling outlets. Otherwise, y our baby monitor would fall out of the outlets. • Make sure the parent unit, the baby unit and the power adapter cords are out of r each of children.

INTERTEK TESTING SERVICES FCC ID: EW780-80818000A 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: DM221 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 DM221 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.”
