Other versions may not comply with FCC technical regulations.The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. NTM-DA1 has been tested and found to comply with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65.PrecautionsSafety Precautions Operate the transmitter and receiver on 5V DC. To operate them from house current, use only the supplied AC adaptors; do not use any other type. Place the transmitter more than 0.9m (3ft) away from your child. Should any solid object or liquid fall into the unit, disconnect the AC adaptor after turning the unit is power off and have the unit checked by qualified personnel before operating it any further.Notes on the AC adaptor Connect the AC adaptor to a nearby easily accessible wall outlet. If trouble occurs while the adaptor is in use, immediately set the Power/VOICE ACT switch of the receiver to OFF and disconnect the AC adaptor from the wall outlet. And also set the Power switch of the transmitter to OFF and disconnect the AC adaptor from the wall outlet. The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off. If you are not going to use the Digital Audio Nursery Monitor for a long time, disconnect both the transmitter and receiver from the wall outlet by pulling out the AC adaptors.If you have any questions or problems concerning your Digital Audio Nursery Monitor, please consult your nearest Sony dealer.http://www.sony.net/Precautions on UsageThis product cannot replace responsible adult supervision of a child. It is designed to assist adults in child supervision. Do not use it for medical monitoring of a sick baby or child. The transmitter detects normal sound levels within a range of 2 to 3m (6 to 10feet) from your child. If the child moves outside of this range, it may not be able to detect sounds from him or her. The transmission range between the transmitter and receiver is up to 270m (900feet) (Line of Sight). It is essential that you check the transmission range and condition of the Digital Audio Nursery Monitor on initial installation, and on a regular basis after that. Stay close to the receiver in order to hear normal sounds from it. Check the volume regularly to ensure that it is set high enough. The sensitivity of the Digital Audio Nursery Monitor can be affected by other devices using 2.4GHz frequency, such as a wireless LAN device, a cordless telephone, or a microwave oven, that may be used near the transmitter and receiver. Using such devices may shorten the transmission range and cause sounds to be distorted. Avoid placing the transmitter and receiver near heat sources or where they are subject to direct sunlight, excessive dust, moisture, or mechanical shock.Cautions on Water-resistance (for the receiver only)The receiver is designed so that it can be used with slight exposure to water, rain, snow and other forms of moisture, but there are several points on which caution should be observed. Do not allow the receiver to come into contact with large amounts of water. Do not immerse the receiver in water. If the receiver is dropped into water, set the Power/VOICE ACT switch to OFF immediately and disconnect the power cord. Do not use it any more and consult your nearest Sony dealer. If the receiver get wet, wipe it off with a dry cloth. Do not pour cold or hot water directly from a faucet or hose onto the product, as it is not of waterproof. If you use the product near water, close the waterproof cover of the DC IN 5V jack firmly. If it is left open, moisture may get inside the product and may cause a malfunction. If moisture has getten inside the product, some may remain in its openings. Shake the product lightly to shed water then wipe the surface. If not, the remaining water will spill out when you move the product.SpecificationsFrequency: Digital 2.4 GHzTransmitting Distance: Approx. 270 m (900 feet) (Line of Sight)TransmitterPower requirement: AC adaptor (DC IN 5 V jack): 100 V-240 V AC, 50 Hz/60 HzDimensions:Normal positionApprox. 53 mm × 62.3 mm × 56.1 mm (w/h/d) (2 1/8 in. × 2 1/2 in. × 2 1/4 in.) incl. projecting partsWhen mounting on the wallApprox. 53 mm × 45.1 mm × 70.3 mm (w/h/d) (2 1/8 in. × 1 13/16 in. × 2 7/8 in.) incl. projecting partsMass: Approx. 41 g (1.45 oz)Power consumption: At the maximum load: ## W (IR LED On)Normal mode: ## W (IR LED Off)ReceiverPower requirement: AC adaptor (DC IN 5 V jack): 100 V-240 V AC, 50 Hz/60 HzAudio power output:0.65 WSpeaker: 28 mm dia., 8 ΩDimensions:When the stand is closedApprox. 51.1 mm × 99.1 mm × 36.1 mm (w/h/d) (2 1/8 in. × 4 in. × 1 7/16 in.) incl. projecting partsWhen the stand is openApprox. 51.1 mm × 97.7 mm × 69.5 mm (w/h/d) (2 1/8 in. × 3 7/8 in. × 2 3/4 in.) incl. projecting partsMass: Approx. 100 g (3.53 oz)Operating temperature: 0 °C - 40 °C (32 °F - 104 °F)Power consumption:At the maximum load: ## WNormal mode *: ## W* When operated with the medium volume level, and Voice Activation offAC adaptor:Input: 100 V - 240 V AC, 50 Hz/60 Hz, 0.3 AOutput: DC 5 V/0.4 ADimensions:Approx. 63mm × 26.8mm × 44mm (w/h/d)(2 1/2 in. × 1 1/16 in. × 1 3/4 in.) excl. projecting partsMass: Approx. 71 g (2.5 oz)Design and specifications are subject to change without notice.[TENTATIVE]](https://usermanual.wiki/Sony-Group/NTMDA1T.User-Manual-UPdate/User-Guide-1917165-Page-1.png)

Charging may take longer, depending on whether or not the receiver is turned on and other ambient conditions.Checking the remaining battery powerWhen the battery power is getting low, a beep sounds and BATT/CHG indicator light of the receiver flashes red.Notes If you consume the battery power completely and leave it like that, the battery life may be affected. Charge the battery by connecting it to the AC adaptor as soon as it has been used up. Even if you do not intend to use the receiver for a long period, charge the battery to its full capacity once every 6months to maintain its performance.Setting upTurning on the powerPower/VOICE ACT switchPower switchTransmitter Receiver1 Set the power switch of the transmitter to ON.2 Set the power/VOICE ACT switch of the receiver to ON or VOICE ACT.You will hear sound from the speaker.Notes When the receiver is turned on while the transmitter is not on, an alarm sounds in the receiver as no signal can be transmitted. We recommend turning the transmitter on first. Do not turn the power on when the receiver is close to the transmitter. Feedback noise will be generated.Tips According to the level of sound detected by the microphone of the transmitter, more SOUND LEVEL indicator lights (up to 3 lights) turn on in red. The receiver sounds an alarm when it is moved out of the transmission range.Turning off the power1 Set the power/VOICE ACT switch of the receiver to OFF.2 Set the power switch of the transmitter to OFF.Customizing the Digital Audio Nursery MonitorAdjusting the volumeThe volume of the sounds you receive varies depending on the loudness of the baby’s voice, distance between the transmitter and the baby, direction of the built-in microphone of the transmitter, obstructions, etc.Set the volume as required using the VOLUME control. If the volume level is set too high and is accompanied by a shrill noise, reduce the volume.To increase sound volume, turn the VOLUME control downward. The green area of the VOLUME indicator is extended.To decrease sound volume, turn the VOLUME control upward. The green area of the VOLUME indicator is reduced.VOLUME indicator(Green)VOLUME controlThe sound volumes decreased.The sound volumes increased.Note The SOUND LEVEL indicator lights turn on according to the input sound level received from the transmitter. The level setting of the VOLUME control does not affect it.Using the Voice Activation functionThe VOICE Activation function eliminates most background noise when the receiver does not detect any sound.This function is usable when it is not required for the receiver to constantly check for sounds from the nursery, such as when the baby is sleeping quietly or the parents are sleeping.1 Set the power/VOICE ACT switch to VOICE ACT to turn the function on.The SOUND LEVEL indicator lights on the receiver turn on according to the sound level from the transmitter (0 [low] to 3 [high] indicators from the left).Tips If no sound is detected, no SOUND LEVEL indicator lights turn on. If the sound is very loud, all 3 indicator lights turn on. You can also hear sound from the speaker.TroubleshootingShould any problem persist after you have made the following checks, consult your nearest Sony dealer. For checking or repairing the Digital Audio Nursery Monitor, the Sony dealer must have your transmitter and receiver together, even if only one of them seems to have a problem.No sound The AC adaptor is disconnected from the wall outlet. The battery of the receiver is used up. The receiver is too far from the transmitter. Volume is low. (The volume is turned down.) In quiet surroundings, the power/VOICE ACT switch of the receiver is set to the VOICE ACT position.Too much noise The receiver is too far from the transmitter.
