Precautions Safety Precautions Operate the transmitter and receiver on 9 V DC. To operate them from a house current, use only the supplied AC adaptor; do not use any other type. For battery operation of the receiver, use one rechargeable battery pack BP-TR10. Should any solid object or liquid fall into the unit, disconnect the AC adaptor and remove the battery, 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 AC adaptors. – Remove the battery 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 in the receiver or operate it on house current as soon as the POWER/ BATT indicator starts flashing and the receiver sounds a beep. The receiver can be affected by other devices in or near your home that may interfere with the signals sent by the transmitter. Such interference can be caused by TV sets, cordless phones, vacuum cleaners, car ignitions, and other electrical devices. You should test the receiver when you expect such devices to be in operation while you are using the Sound-Sensor Nursery Monitor. The signal from the transmitter can be received by another receiver, as it uses a public air wave. Cautions on Water-resistance (for the receiver only) This unit 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 it to come into contact with large amounts of water. Do not immerse it in water. If water should get on it or if it should fall into water, take it out immediately and wipe it off with a dry cloth. To prevent the battery from corroding, wipe out the interior of the battery compartment as follows: – Open or close the battery compartment with dry hands in a place without exposure to any water. – Wipe off the battery and the inside of the battery compartment. Give special attention to the contacts so that no water remains on them. Troubleshooting Should any problem persist after you have made the following checks, consult your nearest Sony dealer.

Setting Up Turning on the power Set the OFF/ON switch of the transmitter and the OFF/ ON/VOICE ACT switch of the receiver to ON to turn on the power. The POWER indicator of the transmitter and the POWER/BATT indicator of the receiver will light up. To turn off the power, set the OFF/ON switch of the transmitter and the OFF/ON/VOICE ACT switch of the receiver to OFF. Setting the frequency channels Up to 27 channels can be set through the CH selectors by changing the combination of three colors (red, yellow and green) on the CH windows. Set the CH selectors of both the transmitter and receiver so that the settings of color combinations shown in the CH windows are the same. Otherwise, the transmitter and receiver will not function. If the settings of the receiver and transmitter are not the same, the RANGE ALM. indicator starts flashing and the receiver sounds a beep. If signal interference occurs Set the CH selectors of both the transmitter and receiver to another setting. Make sure that both the settings shown in the CH windows are the same. Setting up the transmitter (See Fig. – ) Place the transmitter within 2 to 3 meters (6 to 10 feet) from a crib or play area. If the child moves outside of this range, the transmitter may not be able to detect his/her sounds. The transmitter must be placed upright during operation. Tips for better reception Place the transmitter at a location as high as practically possible such as on a table or on a wall. Make sure that the transmitter is not covered or obstructed for picking up sounds. Make sure that nothing touches the antenna during operation. Notes Do not place transmitter or cord within reach of children. Do not place transmitter or cord in, or attach to, crib or playpen. Never use extension cords with AC adaptors. Only use AC adaptors provided. Position the transmitter with the front side where the built-in microphone is located facing the baby. Do not use the antenna as a carrying handle. Do not use the antenna to hang the transmitter on the wall. Be sure to use the cavity for hook. Monitoring through the receiver (See Fig. – ) The longest distance you can place the receiver from the transmitter varies according to obstructions and other conditions. First, test the operating range with the assistance of another adult, or by placing a radio, etc., near the transmitter. If you move outside the effective operating range of the system, the RANGE ALM. indicator lights up and the buzzer sounds. In such a case, move closer toward the transmitter until the indicator and the buzzer turn off. Tips for better reception Keep the receiver upright during operation. Make sure that nothing touches the antenna during operation. The VOICE ACT function eliminates most background noise when the receiver does not detect any sound. Set the OFF/ON/VOICE ACT switch to VOICE ACT to turn on this function. When the receiver receives sounds from the transmitter, the MONITOR indicators light up from left to right in five steps depending on the sound level. Only one indicator may light up if the sound from the transmitter is not loud, or all the indicators may light up if the sound is very loud. You can also hear sounds through the speaker. To adjust the volume The 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 VOL. If the volume level is set too high and is accompanied by a shrill noise, reduce the volume. The volume level can be adjusted between the smallest and biggest dots on the VOL. Notes Avoid placing the units near heat sources or where they are subject to direct sunlight, excessive dust, moisture, or mechanical shock. Be careful not to drop the receiver in water, or drop any liquid over it. Do not use the antenna as a carrying handle. Do not use the antenna to hang the receiver on the wall. Be sure to use the cavity for hook. To a wall outlet AC adaptor Tab BP-TR10 battery pack Red Black * The attached packing is used to ensure water-resistance of the battery compartment.

Battery life (approx. hours for continuous standby) (JEITA*) Sony rechargeable battery pack BP-TR10 22 * Measured by JEITA (Japan Electronics and Information Technology Industries Association) standards. The actual battery life may vary depending on the circumstance of the unit. When to recharge the rechargeable battery pack If the sound becomes distorted or interrupted, we recommend that you recharge the battery pack. When the battery pack is used up, the POWER/BATT indicator starts flashing and the receiver sounds a beep. If the battery pack is extremely used up, the beep may be interrupted or the POWER/BATT indicator may flash when you turn on the power. Recharge the battery pack as soon as possible in either case. Recharge the battery pack for more than 22 hours so that the battery pack is fully charged. Turn off the receiver before charging the battery pack. The CHARGE indicator remains lit even after charging has been completed. Charging duration Approximately 22 hours are required to charge the battery pack to its full capacity. Notes on the rechargeable battery pack The battery pack will gradually discharge over a long period of time, even if not in use. If you leave the weak battery pack inside the receiver without charging it, the battery pack will be completely discharged. It may require several times of charging to recover to its full capacity. Notes on replacing the rechargeable battery pack If the battery pack lasts only a few minutes even after 22 hours of charging, the battery life has expired and needs replacement. Before replacing the battery pack, make sure that the receiver is turned off. Replace the battery pack with a new one. Contact your local Sony authorized dealer or service center, and ask for a Sony BP-TR10 rechargeable battery pack. Do not use any other rechargeable battery pack. To operate on house current (See Fig. – ) Open the lid of the DC IN 9V jack of the receiver. Connect the supplied AC adaptor to the DC IN 9V jack and plug it in to a wall outlet. The CHARGE indicator will light up whether or not the receiver is turned on.
