Setting up the transmitter (See Fig. C– ) 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 • Keep the transmitter out of the reach of the baby. Do not place the transmitter inside a crib or playpen. • 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. C– ) 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. Using Belt Clip (See Fig. C– AC power cord ) The receiver has a belt clip located on the rear. It is convenient when you move around, for example, when you clean up the room, etc. Insert your finger into the cavity for hook and slide upwards as illustrated, then hang the belt clip onto your belt.
