A.2.1 Connect to Telephone
A.2.2 Connect to Telephone Headset
Note that all connections jacks are located at the bottom of the unit. Flip over
the amplifier, unplug the handset cord from your telephone base unit and
insert it to the Modular Jack for Telephone Handset (12). Then, use the
phone cord provided with RJ-11 modular plug at both ends to connect the
control unit to your telephone. Plug one end of the cord to your base unit (A)
and the other end to the Modular Jack for Input from Telephone Unit
(11) at the back of the unit.
One thing you will notice right away is that A30 Amplifier comes already
installed with a cable connected to the bottom of the amplifier, specifically to
the Modular Jack for Telephone Headset (15). The other end of the
cable is a Quick Disconnecting Cable (QD) plug, as illustrated below.
To connect to any Accutone telephone headset, disconnect the QD on your
headset, and connect the top half of your headset cable to the QD cable
extended from the amplifier. Please note that this quick disconnector is
specially designed for users who are always on the move, by allowing users
to quickly connect and disconnect to the device.
* For pairing the A30 amplifier with non-Accutone headset, you must unplug the entire cable from the
modular jack (15) and connect it with the telephone headset’s standard modular jack. We do not
recommend such pairing, as not all telephone headsets match the standard A30 configuration.

B.1.1 Telephone Pairing

Different telephones have different configurations, so you need to first pair
your amplifier with your telephone. The Telephone Configuration Switch
(13) at the bottom of the unit allows user to effectively select a proper
setting to pair with their telephone by sliding it to different positions, namely
position (1-2-3).

B.1.2 Adjusting the Microphone Gain Level
While you are still online with someone on the other end, check with them
your microphone gain level. Make adjustments to the Microphone Gain
Level Rotary Control (14) using the screwdriver provided. Turn clockwise
to increase volume, and counter-clockwise to reduce.

* You should only need to make this adjustment ONCE.
B.1.3 Adjusting the Rotary Volume Control
To pair your amplifier, you need to make
a call to someone. With all the cables
properly connected, make sure all three
buttons on top of the unit are all
released. (There should not be any
white line on in front of the buttons)
! no white line!
The Rotary Volume Control (2) located on the top of the unit allows user
to adjust the volume of the headset speaker. Rolling the rotary control up
will increase the volume and rolling it down will decrease it. Do not overturn
the control, as high volume will cause damage to your hearing.
Increase Volume
roll upwards
Put on your headset and lift up the
handset to call someone, if the person
on the other end cannot hear you or
you cannot hear them, switch to the
next position until you find the best
position, but don’t hang up yet.

B.1.4 Headset/Handset Application
B.1.6 Voice Enhancement Function
The Headset/Handset Application Switch (3) located on the top of the
unit allows user to choose between using headset or the handset of the
telephone base unit. When the button is pressed down, the handset is
chosen, which means the default (released) status is for headset usage.
The Voice Enhancement On/Off Switch (5) allows user to enhance a
caller’s voice in a noisy environment. When pressed, the voice enhancer
adjusts the signal so that the background noise of the caller is filtered out
while the caller’s voice is amplified. However, the sound quality may seem to
slightly decreased. Release the button to return to normal mode.

B.1.5 Microphone Mute Function
The Microphone Mute On/Off Switch (4) allows user to place a caller on
hold by pressing it down. When pressed, the caller does not hear the user,
but the user can still hear the caller. To resume talk, press it again to release
the mute function.
!
Read this section carefully before your proceed to adjust any volume controls.
When adjusting either the Microphone Gain Level or the Headset
Speaker Volume, do not turn to maximum level from the start. You should
first try with a lower volume settings and slowly adjust to an appropriate
level. Be careful if you combine a high microphone gain level with a high
speaker volume, as this may result with a high-pitched feedback noise
(“squealing” sound). Such noise can cause severe damage to your hearing,
and prolonged usage under such settings will damage the headset and the
amplifier.

items to check
Check to make sure you have a standard C-battery
#
inserted in the amplifier, as power is required.
Have you selected the proper pin-alignment settings from
#
the configuration switch located in the bottom of the A30?
Make sure the handset button is not pressed.
#
If your telephone has a headset button, press the headset
#
button or lift up the handset from its cradle.
Try to turn the speaker volume up a bit by rotating the
#
rotatory volume control.
Is your headset properly connected to the amplifier, make
#
sure it’s plugged into the frontmost jack on the bottom of
the amplifier.
If all fails, contact your local distributor for another model
#
of amplifier, as your telephone may not be compatible with
the A30 amplifier.
Make sure the Mute button is not pressed down.
#
Check to see if the Microphone Volume is set too low, the
#
microphone volume adjustment is made from the bottom
of the amplifier.
It’s possible that the battery has ran out, try replacing new
#
batteries.
Select through the microphone selector for a better
#
setting.
I hear my voice too
loud and there is a
squealing sound.
The Microphone Volume Control is set too high or the
#
Reception Volume Control is set too high, reduce either
one or both for the perfect settings.
The other end
cannot hear me well
no matter which mic
setting I choose.
The A30 amplifier is designed for optimal performance for
#
the majority of the telephone models, but for some
telephone models the microphone gain level is too low for
the headset. Contact your local distributor for assistance.
items to check
problem
The device was
working fine, but
after a prolonged
period of inactivity,
it has no response
when I turn it on.
Make sure all the cables are properly hooked up, especially
#
the patch cable connecting the amplifier with the
telephone terminal.
Then, check to make sure there is battery or else you
#
should replace new batteries.
Now make sure there is signal coming from the telephone,
#
you can test this by selecting Handset/headset Switch to
HANDSET and pick up the handset to check if there is a
dial-tone. If no, then the problem is with the telephone or
the network; if yes, then un-press the handset button, if
there’s still no signal, then the headset has become
defective. Contact your local distributor for headset
replacements
During a telephone
conversation, the
voice transmission
or reception
suddenly ceased.
Make sure you change your batteries every few months, as
#
The caller can hear
my breathing sound,
and the noise is too
loud.
Telephone calls made to different systems and locations
#
may vary in their reception level. To reduce breathing
sound, you should keep the foam windscreen attached to
the microphone on your Accutone headset, or adjust the
Microphone Volume according to different calls.
When pressed the
voice-enhancement
button the caller’s
voice becomes very
strange.
The Voice-Enhancement feature is used to reduce back#
ground noise from the caller. It works by flattening out the
sound frequency on the loudspeaker, so it’s normal that
the caller’s voice becomes “flattened”. You should be able
to hear them better even in a very noisy environments.
mic-transmission may be affected if the power voltage is
dropped to a certain level.
Even with low-battery, the amplifier will not drop any
#
reception signal (speaker side), so if you hear interruptions
to the speaker side, make sure the headset plug is
fastened, also the Quick Disconnector is firmly connected.
