Operation; Loudness Adjustment; Using The Telephone - BEAN QSA User Manual

ON/OFF
The QSA turns on and off by opening
and closing the battery door.
Note: It is not necessary to remove
the battery as long as the door is open
wide enough to disable the circuit.
There are two loudness settings,
Normal (N) and High (H).
N: (switch toward the body of the QSA)
• 15-dB mild amplification and treble
boost for soft sounds. No amplification
for loud sounds
H: (switch away from the body of the QSA)
• 8-dB more amplification than the
N position, and treble boost for soft sounds
• Mild amplification for loud sounds

Using the Telephone

It is not necessary to remove the QSA when using the
telephone. Practice. If you are comfortable holding the
phone on or near the ear and a whistling sound does
not occur, the QSA can remain in the ear during a call.
