SES- FA1 S ET UP INSTRUCTIONS
1. Secure the units in a safe location, where they will not be bumped or dropped or fall and where
there is room around the unit so nothing will interfere with the fiber optic cabling causing it to
bend in a tight radius or bend sharply in any way as this can severely affect the signal transfer
2. Carefully connect your source(s) to the transmitters input(s) and the receiver units output(s) to
your receiving devices input(s) using the RCA inputs on the transmitter and the RCA output
connectors on the receiver unit,
3. Please note that all audio, on either the transmitter (Tx) or receiver (Rx) unit, must be line level!
4. CLEAN* the ST fiber optical cable contacts that will be used for connecting the Tx and Rx units
and insert the fiber into the ST connections and secure like you would secure a bayonet BNC:
while pressing lightly in on the connector twist it in a clockwise direction about 1/8 to 1/4 of a
turn and then release, the connector should stay inserted and have backwards spring pressure
holding the bayonet in place
5. Lastly connect the AC power supplies to the units and plug the power adapters into an ac
power source: 100v-240v AC 50/60Hz input range –this will power up the units
*ALL FIBER OPTICAL CABLE CONTACTS [THE ENDS ARE CALLED CONTACTS: THE PART THAT IS
INSERTED AND MAKES CONTACT TO ENABLE THE TRANSMISSION OF THE LIGHTWAVES THROUGH THE

812 Kings Hwy • Saugerties, NY 12477 • www.sescom.com

INPUTS.FAILURE TO CLEAN THE CONTACTS CAN NOT ONLY DAMAGE THE UNITS OPTICS OVER TIME BUT
CAN RENDER THE CABLE AND THE DEVICE USELESS PERMANENTLY. FURTHERMORE CLEANING WITH
CLEANING METHODS OTHER THAN CLEANING KITS SPECIFICALLY FOR FIBER OPTICS ARE
UNACCEPTBLE AND MAY EVEN ADD CONTAMINANTS THAT CANNOT BE SEEN BY THE NAKED EYE TO
