Before You Begin Thank you for choosing the Sony Sound-Sensor Nursery Monitor! Before operating the Sound- Sensor Nursery Monitor, please read these instructions thoroughly and retain them for future reference. Features • Up to 27 channels (NTM-910) or 9 channels (NTM-900) for maximized reception. • Voice Activation eliminates most background noise for a more peaceful sleep. • 5 indicators for monitoring sound levels. • RANGE ALM., POWER/BATT and CHARGE (NTM-910) indicators allow you to know the operating condition of the receiver. • Water-resistance allows operating the receiver in slight moisture areas such as kitchen or bathroom. • Operating on rechargeable battery pack (NTM-910). Precautions Safety Precautions • Operate the transmitter only on 120 V AC, 60 Hz; and the receiver on 9 V DC. To operate the receiver on house current, use only the supplied AC power adaptor; do not use any other type. For battery operation, use one rechargeable battery pack BP-T50 (NTM-910) or two size AA (R6) batteries (NTM-900). • Should any solid object or liquid fall into the unit, disconnect the AC power adaptor and remove the battery/batteries, and have the unit checked by a qualified personnel before operating it any further. • If you are not going to use the system for a long time: – Disconnect both transmitter and receiver from the wall outlet by pulling out the plugs of both AC power cord and AC power adaptor respectively. – Remove the battery/batteries out of the receiver to avoid damage from battery leakage. If you have any questions or problems concerning your system, please consult your nearest Sony dealer. Precautions on Usage This 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 3 meters (6 to 10 feet) from a child. If the child moves outside of this range, it may not be able to detect sounds from him or her. • It is essential that you check the operating range and condition of the Sound-Sensor 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. Recharge the rechargeable battery pack (NTM- 910) or replace the batteries (NTM-900) in the receiver or operate it on ho…

FCC ID : AK8NTM900 Model : NTM-900 CIRCUIT DESCRIPTION of NTM-900 NTM-900 is made up from a pair of components, which are a transmitter(TX) and receiver(RX). So, though FCC application of Certification is only applied for TX of NTM-900, explanation of TX and RX are described on “Circuit Description”. Transmitter(TX) part Configuration : crystal-controlled PLL circuit Transmitting frequency of the TX has 9 channels (please refer to the below). The channel is manually selected by SW302 and SW304. 1ch 902.200MHz 6ch 903.300MHz 2ch 902.300MHz 7ch 904.100MHz 3ch 902.400MHz 8ch 904.200MHz 4ch 903.100MHz 9ch 904.300MHz 5ch 903.200MHz Signal-flow path After IC301 get selected channel signal (which is occurred by SW302 and SW304) through IC302, fundamental frequency is oscillated by Phase Locked Loop circuit (IC301, Q302, D301 and Low Pass Filter). Range of the frequency is 451.1MHz to 452.150MHz. And, second harmonic frequency only of it is amplified by Q301. The frequency(902.2MHz - 904.3MHz) will take a route to FL301(Band Pass Filter), and finally to the Antenna for the transmission. MIC amplifier Voice sound picked up through the MIC will be amplified by Amplifier of IC301, then the sound will be injected to the D301(Variable Capacitor diode) and FM modulation is conducted. Voltage stabilizer circuit Floating voltage will be stabilized on Q305 and D302. FCC ID : AK8NTM900 Model : NTM-900 Receiver(RX) part Configuration : crystal-controlled PLL circuit Receiving frequency of the RX has 9 channels (please refer to the below). The channel is manually selected by SW2 and SW4. That receiving type is Lower Heterodyne with Intermediate Frequency (IF) of 10.7MHz. 1ch 902.200MHz 6ch 903.300MHz 2ch 902.300MHz 7ch 904.100MHz 3ch 902.400MHz 8ch 904.200MHz 4ch 903.100MHz 9ch 904.300MHz 5ch 903.200MHz Signal-flow path A RF-signal received through the antenna will take a route from Q1(RF Amp) to Q2(MIX), FL2 and FL3(Band pass filter), IC1(IF-Amp, Quad detector, Pre-Amp, Expander) and IC6(AF power amp), and finally to speaker. Fundamental frequency(445.750MHz- 446.8MHz) is made by Phase Locked Loop circuit (IC1, Q3, D1 and Low Pass Filter). And, second harmonic frequency(891.5MHz- 893.6MHz) of it will take a route to Q2(MIX). Sound monitor A part of AF signal is branched to Q4(Amp) and the signal is converted to DC voltage. CPU(IC2) reads the DC voltage level and illuminate LEDs(D6-D10). Voice activated system In case AF signal can not be detected for 5 seconds, sound is muted by Q5, Q6, Q7 and Q8 until next AF signal can be detected. Range alarm When AF signal can not be detected (e.g. : reciever is out of area etc.), the device turns the light(D5) on and off, and beep sound is sounded from the speaker. Battery monitor When battery voltage level is down, the device turns the light(D4) on and off, and beep sound is sounded form the speaker. Then the power supply is automatically stopped.
