Controls for adjusting the
microphone gains are located
along one side of the amplifier.
Please note these are factory
set prior to despatch and
should require no adjustment
unless exceptional audio con-
ditions are encountered. To
increase or decrease the gain
on either the Customer's
Microphone or the Staff
Microphone, first make sure
that both volume controls on
the front of the amplifier are
turned fully clockwise for
maximum volume. Then turn
the appropriate gain poten-
tiometer
clockwise
(to
increase gain) or anticlock-
wise (to decrease gain) using
the
trim
tool
supplied.
Substantial changes in the
audio levels can be achieved
by relatively minor adjust-
ments of the gain controls.
Should feedback occur whilst
making adjustments, turn the gain controls anticlockwise until the feedback disappears and the
desired sound level obtained. The set-up switch is factory set and should not be altered.
If the SecuriCom System has been supplied with optional Induction Loop Facility, the package will
contain an STS A30 audio amplifier, a P43 Power Supply Unit, a suitable Induction Loop Aerial, (either
IL-E93, IL-E94 or IL-E95) and a self adhesive yellow induction loop sign (IL-E97). The principle of the
system is to transmit sound via an electro-magnetic field which is picked up and amplified by a tele-
coil fitted inside customers' hearing aids.
Correct positioning of the Induction Loop Aerial is critical to ensure the loop performs to its full
potential. It should be fixed under the desk-top or counter centrally so customers wearing hearing aids
receive the signal. In the case of the IL-E94 (Loop Pad Aerial), for best results, this can be folded so
that half is mounted horizontally under the counter and the other half mounted vertically, facing the
customer. Make sure that the Induction Loop self adhesive yellow sticker is displayed in a prominent
position.
The Induction Loop Aerial connects to terminals
19 and 20 on the Amplifier using the appropriate plug
and socket.
The control for adjusting the Induction Loop gain is
located on the side of the amplifier and output may be
adjusted by using the trim tool and an induction loop
tester. Turn the gain potentiometer clockwise (to
increase gain) or anticlockwise (to decrease gain).
