ADA
Description:
Maximize a student’s ability to listen with the Personal FM System 350 RCH from Williams Sound.
Personal FM systems deliver the teacher’s message directly to the student’s headphones by way of
FM signal, eliminating background noise and other distractions. It’s perfect for classrooms, job
training, consultation and more. Portable, no wire, no hassle. Each PFM 350 RCH system has a
range of up to 150 feet, and will operate up to 60 hours at one time. Versatile 3.5 mm jack allow
for a variety of earphone and headphone options, or equip it with a neckloop and it is compatible
with most telecoil-equipped hearing aids. The PFM 350 RCH includes an R31 receiver, which fea-
tures a sensitive environmental microphone: this gives the listener more flexibility on what they
want to hear. By turning on the environmental mic, they can listen to a nearby classmate speak
more clearly. Each PFM 350 RCH system includes a CHG 200A drop-in style charger for charging up
to (4) AA BAT 026 batteries (included).
