The Microphone-Telecoil-Off
switch features three program
positions (see figure 12A). During
normal use the M-T-O switch
is worn in the microphone (M)
position. Moving the switch to the
telecoil (T) position changes the
program to telecoil.
In the telecoil position for both the Microphone-
Telecoil push button and Microphone-Telecoil-
Off switch, your instruments are compatible
with the electro-magnetic field of the telephone
and you will be able to hear without a whistling
sound (feedback).
