Thank you for selecting the UA-50 Universal Handset/Headset
Telephone Amplifier. This unique amplifier is compatible with
virtually any modular connected phone system. UA-50 is the
only product of its kind that amplifies sounds for both handset and
headset. It enhances the clarity and increases incoming volume
(up to 170 times) for louder and clearer conversations. UA-50
comes with these items:
1. Install a 9-volt battery (Not Included). Connect telephone handset and
headset (optional) to UA-50 as shown. Use only the provided “short cord”
to connect UA-50 to the phone base. (Note: Ignore the ON / OFF indicator
while doing any switch setting. It is irrelevant at this time.) For your safety,
always disconnect UA-50 from the phone base before replacing its battery.
Use a coin to ply open the battery door.
1. Press the Headset button on UA-50, the Headset indicator should now
be ON. You should now be able to hear the other party on the headset.
Place the handset on the table or desk so it remains off-hook while the
headset is being used.
2. Make sure the other party can also hear you. If not, turn over the UA-50
and move the Headset Mic (microphone) switch from Position 1 to 2 or
vice-versa.
Record this position for future reference.
3. To go back to the handset mode, simply press the Headset button again,
the Headset indicator should now be Off.
4. The ON / OFF indicator light should be on while you are talking. It will go
off in 8-15 seconds after going on-hook (or if there is no sound / voice for
15 seconds).
5. Return the handset back to its cradle to end the call
6. Please install the 9-volt DC power adapter now. Plug the adapter to the
wall outlet. Connect its output plug to the DC jack on the rear of the unit.
7. DC adapter now provides normal operating power while the installed bat-
tery provides backup power. The battery should be changed once every
two years or sooner if you notice the ON / OFF indicator failed to come
on during a power outage.
4. While talking on the phone, verify you can vary the handset volume by
rotating the volume control on the amplifier. (Caution: Lower the volume
control if you notice there is squeal sound in the handset).
5. While on the phone, try different Tone control settings to find the one with
the best incoming sound clarity. Lower the volume if you notice a squeal-
ing sound in the handset. Keep this setting for all future calls. You do not
need to change this tone setting again.
Record this tone setting for future
reference.
6. Press and hold the BOOST button down. Verify the incoming voice
becomes louder and the BOOST LED is on. You must release this button
when talking because your voice is muted if this button is held down.
7. The ON / OFF indicator light should be on while you are talking. It will go off
in 8-15 seconds after going on-hook (or no sound / voice for 15 seconds).
2. Set Volume control to its mid-point. Set Tone Control Switch to Position 2. Set
Headset Mic switch (on the bottom) to Position 1. Make sure Headset button
is up and Headset LED indicator is OFF.
3. Setting the Compatibility Switch: There are 7 positions on this switch. Posi-
tions 1 to 6 are for compatibility setting use. Position 7 is a “by-pass” position
and is not for normal setting use. Position 7 offers no amplification and should
only be used in case of emergency when there is a total power outage.

A. Set Compatibility switch to Position 1 (Note: This is the most popular setting and is used
by most phones. Ignore ON / OFF indicator status while setting this switch. It is not
relevant at this time.)
B. Lift up the handset and verify you can hear a clear dial tone.
C. If there is no clear dial tone, hang up the handset and move the Compatibility switch to
the next position and repeat Step B.
D. If you do get a clear dial tone, verify the dial tone loudness can be changed by rotating
the volume control. If there is change in dial tone loudness, go to Step F.
E. If the dial tone loudness can not be changed by rotating the volume control, hang-up the
handset and move the Compatibility switch over to the next position. Repeat Step B.
F. Use the telephone keypad to make a call and verify you can hear each other.
G. If you can hear each other, then the present Compatibility switch setting is the correct
one and you are done.
Record this switch setting for future reference.
Go to Step 4.
H. If not, try the next Compatibility switch position until you can hear each other clearly.
(Note: Feel free to experiment with any switching setting.)
Questions?
1. ON / OFF indicator never comes ON: Replace the battery and check the
DC power adapter connection.
2. Can not hear dial tone or can not hear each other on handset: Make
sure the Headset indicator is not ON. Make sure the compatibility switch
did not get changed by accident. If necessary, repeat A to D of Step 3
above.
3. Can not hear each other on headset: Make sure the Headset indicator
is ON. Make sure the Headset Mic switch is set correctly. (See Step 2
under Headset Function).
4. There is a loud squeal in my handset / Headset: The volume or tone is
set too high, lower volume or tone setting to stop squeal.
