INTRODUCTION
Sound Associates manufactures two types of wireless stethoscope-style headset recei ers
designed for professional applications: the SA1531H (single-channel) and SA1533H (3-
channel). Our headsets are equipped with a sophisticated recei ing circuitry with multiple
recei ing diodes to increase sensiti ity. Also, high-performance micro speakers are utilized to
gi e the user remarkable audio reproduction.
The SA1520 and 1530 series headsets are compatible with most infrared transmission systems
currently in use. They are designed with a new industrial-strength chassis for added durability in
commercial applications. Its ad anced mechanical design ensures years of trouble-free use,
while making the headset comfortable to wear.
The SA1531H is designed to recei e a frequency modulation of 2.3 MHz, while the SA1533H is
selectable between 2.3 MHz, 2.8 MHz and 95 kHz. The recei ers are worn under the chin,
stethoscope-style and are powered by a light weight lithium polymer rechargeable battery,
designed especially for the Sound Associates’ line of recei ers.
To ensure proper set up and use of the equipment, the following instructions should be read
completely before attempting to use your recei er. If you require further assistance, please call
our Customer Ser ice Department Monday-Friday 10:00 am - 5:30 pm at (888) 772-SOUND
(7686).
HEADSET VS. NECK INDUCTION LOOP
The SA1520 series of infrared headset recei ers is equipped with an audio jack to comply with
re isions to the Americans With Disabilities Act, effecti e March 2011. The jack will
accommodate most external de ices that use a 3.5 mm (mini) jack including neck induction
loops and Cochlear de ices. Inserting the plug into the jack automatically mutes the amplifiers in
the earpiece and acti ates the external de ice. Note: The hearing aid must be equipped with
a “T” switch or have a telecoil setting to use a neck induction loop. The combination of the
two de ices is likely to gi e the user greater olume and intelligibility than with the hearing aid or
headset alone.
UNPACKING UNIT

by shipping. If the unit is damaged due to shipping, please keep all packing material and
contact the shipping company as soon as possible. Only the consignee may institute a claim

Using the Receiver
The recei er is worn stethoscope style, under the user’s chin, with the Sound Associates logo
facing away from the body. (The SA1505 rechargeable battery must be inserted firmly into the
bottom of the recei er.) The recei er’s “on/off” switch is located internally and turns on
automatically when worn; and shuts off when remo ed. The olume is adjusted by the slide
control located on the unit face.
Location and Use of Controls
1 – Channel Selector: (Model
SA1533H only) The recessed selector
button toggles to one of three positions:
2.3 MHz (left), 2.8 MHZ (center), and 95
kHz (right).
2 – Audio Jack: Fits most 3.5mm audio
plugs. For use with neck induction
loops, Cochlear de ices and other
compatible de ices. Note: inserting a
plug into jack will automatically mute
volume in the earpieces of the headset.
3 – Rechargeable attery: (Model SA1505) 3.7 olt that will run approximately 6 hours without
recharging. It can be recharged while in the headset using the drop-in charger or battery slots
on the SA1401 transmitter or SA1905-10 multi-charger (both sold separately).
4 - Volume Control: A slide control to adjust the olume for each headset. With the Sound
Associates logo facing away from you, slide the control to the right to increase the olume.
5 – Silicone Ear Tips: (Model SA1520ST) Remo able ear pieces are easily cleaned with mild
detergent and warm water or replaced when dirty.
