When you are not going to use the video monitor for some time, store the parent unit, the baby unit and the adapters in a cool, dry place. Below are the questions most frequently asked about the video monitor. Can I turn the parent unit display screen off but keep hearing sounds from the baby unit? Yes, press | LCD ON/OFF on the parent unit to turn off the screen. The parent unit display will also dim automatically after being inactive for some time. In both instances, you will still be able to hear all sounds from the baby unit. Press any key to turn the screen back on. Why is the baby unit not responding normally? Try the following (in the order listed) for a common cure: 1. Disconnect the power to the baby unit. 2. Wait a few minutes before connecting power back to the baby unit. 3. Reboot the parent unit. Why is my screen in black and white? The baby unit has a light sensor that measures ambient light. When the ambient light is dim, such as during night time or in a dark room, the baby unit activates its infrared LEDs, and displays the camera images in black and white night vision. Why does my baby unit show offline? Why is the connection lost every now and then? The baby unit may have lost connection to the Wi-Fi router. Check your network and router settings. Other electronic products may cause interference with your baby unit. Try installing your baby unit as far away from these electronic devices as possible. Why can’t I hear a sound/Why can’t I hear my baby crying? The parent unit speaker volume may be too low. Press on the parent unit to increase the volume. You may have set a low sound sensitivity level. Set the sound sensitivity to a higher level. For details, go to www.vtechphones.com for online help topics. Frequently asked questions General product care Storage mount the baby unit (optional) 1. Place the wall mount bracket on a wall and then use a pencil to mark two holes in parallel. Remove the wall mount bracket and drill two holes in the wall (7/32 inch drill bit). NOTESNOTE Notes • Check for reception strength and camera angle of the baby unit before drilling the holes. • The types of screws and plugs you need depend on the composition of the wall. You may need to purchase the screws and plugs separately to mount your baby units. 2. If you drill the holes into a stud, go to step 3. • If you drill the holes into an object other than a stud, insert the wall plugs into the holes. Tap gently on the ends with a hammer until the wall plugs are flush with the wall. 3. Align the wall mount bracket and screws with the holes in the wall as shown. Tighten the screw in the middle hole first, so that the wall mount bracket position is fixed. You can tighten the other screw in the top hole. 3. Insert the screws into the holes and tighten the screws until only 1/4 inch of the screws are exposed. 4. Place the baby unit on the wall mount bracket, and then slide it forward until it locks into place. Align the holes on the wall mount bracket with the screws on the wall, and slide the wall mount bracket down until it locks into place. 5. You can maximize your baby unit’s viewing angles by tilting the wall mount bracket. Hold the baby unit, and then rotate the knob in anticlockwise direction. This will loosen the joint of the wall mount bracket. Tilt your baby unit up or down to adjust to your preferred angle. Then, rotate the knob in clockwise direction to tighten the joint and secure the angle. OR 4. Place the baby unit on the wall mount bracket, and then slide it forward until it locks into place. Connect the power adapter to the baby unit and a power supply. 1 2 Need help?

INTERTEK TESTING SERVICE FCC ID: EW780-2529-00A MPE Analysis Report The Equipment-Under-Test (EUT) is a Video Monitor - Baby Unit. It has a microcontroller and 2.4GHz RF module. The EUT is powered by a 5V DC AC/DC adaptor. For Maximum Permissible Exposure (MPE) evaluation of the unit, the maximum power density at 20 cm from this transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65 and meet the requirement listed in K DB447498 D04 V01. For the 2.4GHz RF portion of the unit, the measured powers among all the measured channels were within its production tolerance. The antenna gain is 0 dBi = 1 (num gain) and its maximum source-based time-averaging duty factor is 100%. From these data and its operating configuration, the exposed power density at a distance (R) of 20 cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: BLE portion Antenna Type: Internal, integral A ntenna Gain: 0dBi Nominal rated power: 7.6dBm Range of Peak Conducted Power: 3dBm to 8dBm WiFi portion The WiFi portion was tested in according with the following power output and in actual application the below limit shall not be exceeded. Operating Mode Range of Peak Conducted Power 802.11b 9dBm to 22dBm 802.11g 9dBm to 22dBm 802.11n (HT20) Nominal Radiated Field Strength 13.9dBm 11.5dBm 10.6dBm 9dBm to 22dBm An internal, integral antenna has been used. Antenna Gain: 0dBi FHSS portion Antenna Type: Internal, integral Antenna Gain: 0dBi Nominal power: 16.01dBm Range of Peak Conducted Power: 13dB m to 17dBm INTERTEK TESTING SERVICE FCC ID: EW780-2529-00A For Maximum Permissible Exposure (MPE) evaluation of the EUT, the maximum power density at 20 cm from this transmitter shall be less than the General Population / Uncontrolled M PE limit in OET Bulletin 65. 1) For the BLE portion, maximum power was 8 dBm. And the maximum source-based time- averaging duty factor is 100%. From these data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET B ulletin 65 as follow: The radiated power = 8dBm + 0 dBi = 8dBm (6.3 mW) The radiated (EIRP) source-based time-averaging output power = (6.3 * 1) mW = 6.3 mW The power density at 20 cm from the antenna = EIRP / 4πR^2 = 0.001253 mW cm-2 2) For the WiFi portion, maximum power was 22 dBm. And the maximum source-based time- averaging duty factor is 100%. From these data, 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 radiated power = 22dBm + 0dBi = 22 dBm (158.5 mW) The radiated (EIRP) source-based time-averaging output power = (158.5 * 1) mW = 158.5 mW The power density at 20 cm from the antenna = EIRP / 4πR^2 = 0.031533 mW cm-2 3) For the FHSS portion, maximum power was 17 dBm. And the maximum source-based time- averaging duty factor is 100%. Fr om these data, 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 radiated power = 17dBm + 0dBi = 17dBm (50.1 mW) The radiated (EIRP) source-based time-averaging output power = (50.1* 1) mW = 50.1 mW The power density at 20 cm from the antenna = EIRP / 4πR^2 = 0.009967 mW cm-2 INTERTEK TESTING SERVICE FCC ID: EW780-2529-00A 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 Internet Music System at least 20cm from nearby persons.” In addition, for this product with multiple transmitter and antenna (BLE portion, WiFi portion and FHSS portion), the requirement of Simultaneous Transmission evaluation has also been considered and has complied with the following conditions of the worse case; MPE1 /Limit1 + MPE2/Limit2 + MPE3/Limit3 ≤ 1 Thus, 0.001253 / 1 + 0.031533 / 1 + 0.009967 / 1 = 0.042753 BLE portion WiFi portion FHSS portion It is concluded that no Simultaneous Transmission evaluation is required.
