Transmitter Features:
SM5-MC transmitters are battery operated. SM5-MC is coded at the manufacturer with a unique address ID. Transmitter has a test
button for programming and follow on operational testing. When activated the RED LED will illuminate and the SM5-MC will
transmit a sound alert to the Silent Call Medallion series receiver. Low Battery YELLOW LED will flash every 10 seconds when
batteries are in need of replacement.
Transmitter Mounting and Location:
The SM5-MC Medallion Series Transmitter is designed for indoor use only. The transmitter case has provisions for mounting to a nail
or screw on the wall. Velcro strip is also provided for mounting on desktop or wall. Avoid mounting transmitter near large metal
objects, other transmitting devices in close proximity or high current appliances that will degrade the transmitter / receiver operation.
Test transmitter mounting location before mounting to ensure proper system operation. Adjust antenna for best results. Transmission
range with a Silent Call Medallion Series receiver is approximately 500 feet
Installation:
1.
Remove your Sound Monitor from the packaging.
2.
Place the Sound Monitor as close to the sound source as possible that you want to monitor (but not within a baby’s reach). For
example, place it on a dresser next to a baby’s bed or next to a telephone, alarm clock or apartment doorbell speaker.
3.
The Sound Monitor can be mounted to any flat surface with the supplied Velcro strips or you can hang it on a wall using the
access hole on the back of the case. This step is not necessary if you will be moving the Sound Monitor from location to location.
4.
Avoid placing the Sound Monitor on a metallic surface. Metal will interfere with the signal transmission and shorten the signal
range.
Operation:
1.
The Sound Monitor operates on 2 AA Alkaline batteries (included).
2.
There is a Yellow LED (low battery indicator light) on the face of the transmitter. When this light comes on you know that the
batteries need replacing.
3.
Slide the on/off switch on the side of the Sound Monitor to the ON position.
4.
Any continuous loud sound will cause the Sound Monitor to activate and the Red LED on the face
of the transmitter will come on. The transmitter then sends a wireless signal, to any Silent Call
Medallion Series Receiver activating the receiver.
5.
Transmission range with a Medallion Series Receiver is about 500 feet.
6.
The Sound Monitor is designed so that brief sounds such as door slams, regardless of how loud
they are, will not activate the Sound Monitor.
7.
The Sound Monitor leaves the factory set to most sensitive position, which should be adequate for
almost all situations. If for some reason the sensitivity needs to be changed, there is an adjustment
dial located behind the battery door. Rotating the adjustment dial clockwise decreases the
sensitivity.
8.
A new feature of the Sound Monitor is the ability to set the Sound Monitor to detect a specific
sound. Remove the battery cover and at the bottom left hand corner there is a 3 position switch.
Switch # 1 ON is for Sound Alert, Switch #2 ON is for Telephone Alert and Switch # 3 ON is for
Doorbell Alert.
Replacement Batteries:
Use two AA 1.5V Alkaline Batteries. AA Batteries may be purchased from local retail stores. Transmitter is shipped with 2 AA
Alkaline Batteries. Batteries may also be purchased Online at
