INTRODUCTION
The SA1401 is designed for professional applications (classrooms, board rooms, small meeting and
conference rooms) as well as for home personal use and is compatible with most infrared receivers
currently in use The drop-in charger is designed only to recharge Sound Associates SA1520 series
receivers
It is designed with a new industrial-strength chassis for added durability in commercial applications

comfortable to wear
The SA1401 single channel, selectable transmitter is designed to emit a frequency modulation of 2 3
MHz, 2 8 MHz or 95 kHz (via selector switch located on the back of the unit )
The SA1401 uses infrared light to transmit audio to the receiver As it is a “line of sight” technology,
the receiver (headset) must be used in direct line of sight with the transmitter The receiver must be
free of any obstructions that would block the infrared light from the receiver
To ensure proper set up and use of the equipment, the following instructions should be read
completely before attempting to use your receiver If you require further assistance, please call our
