Safety Warnings
CAUTION!
The Pocketalker is capable of producing very loud sound levels.
To prevent sound levels greater than 130dB that can potentially
damage hearing with long-term exposure, use only earphones
and headphones supplied by Williams Sound. The Williams
Sound Headphone model HED 026 should not be used with the
Pocketalker as it can produce sound levels greater than 130dB.
CAUTION!
This product is designed to amplify sounds to a high volume level
which could potentially cause hearing damage if used improperly. To
protect your hearing and the hearing of others:
1. Make sure the volume is turned down before putting on the
earphone or headphone. While wearing the earphone or
headphone, adjust the volume to a comfortable level.
2. Set the volume level at the minimum setting that you need to hear.
3. If you experience feedback (a squealing or howling sound), reduce
the volume setting and move the microphone away from the
earphone or headphone.
Do not allow children or other unauthorized persons to have access
to this product.
WARNING!
1. Do not use this apparatus near water.
2. Clean only with a damp cloth. Do not use alcohol or any other type
of cleaner.
3. Do not use near any heat sources such as radiators, heat registers,
stoves, or other apparatus that produce heat.
4. Use only attachments/accessories specied by the manufacturer.
5. Do not use the product with a neckloop in areas where the
neckloop could get pulled or caught in a machine.
SERVICING OR ATTEMPTING TO SERVICE THIS DEVICE WILL VOID THE
WARRANTY.
Refer servicing to qualied personnel. Servicing is required when
the unit has been damaged in any way; if liquid has been spilled into

Using the built-in T-coil with a Loop System
The Pocketalker can be used with loop systems. When the T-coil
switch on the Pocketalker is enabled, the Pocketalker disables the
microphone input, picks up the loop signal, and sends the audio
through the headphone jack.
To use this feature:
Follow the “Getting Started” instructions and instead of step 8,
ip the T-coil switch to the “T-coil” position (up towards the T-coil
symbol). The T-coil “On” LED indicator above the switch will light
up.

Note: For best performance when using the t-coil feature, the
Pocketalker must be in a vertical orientation. This ensures the best
magnetic coupling to the loop system.
Recharging NiMH Batteries
The Pocketalker can recharge NiMH batteries when used with an
optional BAT KT7 (US) or BAT KT8 (International) charging kit.
1. Verify or change battery switch to the NiMH position.
2. Verify or insert NiMH batteries into battery compartment.
3. Using the included USB A to USB Micro-B cable, plug the
USB Micro-B end into the USB Micro-B charging port on
the Pocketalker. Plug the USB A end into the USB A port
on the power supply included with the charging kit. Plug
the power supply into a wall outlet.
4. The charging indicator will blink slow while charging, and
then will stay on solid when the unit is charged.
WARNING! Do not attempt to charge Alkaline batteries!

Listening during conversations with others
The Pocketalker picks up sounds and boosts them according
to the volume you’ve set. For best results, place or hold the
Pocketalker’s microphone as close as possible to the person
who is speaking.
Seated
Many users set the Pocketalker on a table if they’re in a
restaurant or small group situation. Aim the microphone in the
direction of the person speaking.
Standing Or Walking
Many users use the Pocketalker “Clip” and attach it to their
pocket, pants or skirt. The lanyard may also be used (see
section “Using the Lanyard”).
In The Car
For conversations in the car, you can use the External
Microphone (MIC 014-R) with the optional 3.5 mm - 3.5 mm
Microphone Extension Cord (WCA 007 WC) and optional Lapel
Clip (CLP 014) to attach the microphone to the shirt or blouse
of your fellow rider (see “Extending the Microphone”).

English
12
Extending the Microphone
When the Pocketalker’s internal microphone is too far away from
the desired sound to be eective, the optional 12 ft, 3.5 mm - 3.5
mm extension cord kit (WCA 007 WC) can be used to extend an
external microphone to a television or another person.
To extend the Microphone:
1. Plug the external microphone into the female end of the
extension cord. Arrange the cord to reach the loudspeaker of
the TV or other person. Plug the male end of the extension
cord into the microphone jack on the Pocketalker.

Using an Optional Neckloop
Williams Sound’s optional neckloop (NKL 001) can be used with
the Pocketalker in situations where the Pocketalker is needed, and
the user has a hearing aid with a T-coil.
How it works: The Pocketalker picks up the sound with the
internal or external microphone, and sends it into the neckloop.
The neckloop magnetically couples with the T-coil in the listener’s
hearing aid(s). With the hearing aid T-coil switch on, the listener
can hear the sound directly in their hearing aid(s).
To use the neckloop: Place the neckloop around your neck as
shown below. While holding the housing with one hand, pull up on
the cord lock bead with the other hand to tighten for comfort. Plug
the neckloop into the headphone jack on the Pocketalker. Turn on
the T-coil in the hearing aid(s). Turn on the Pocketalker and adjust
the volume to a comfortable listening level.

Hints & Tips
The Pocketalker has been designed to be as easy to use as
possible. However, if you have trouble, check the following:
1. If using an external microphone, make sure the microphone is
plugged into the “External Mic” jack and the T-Coil switch is
set to “O”. Make sure the earphone or headphone is plugged
into the “Headphone” jack . If using the T-Coil on the
Pocketalker, make sure the T-Coil Switch is on and verify that
the T-Coil indicator LED is lit.
2. Make sure the batteries are not depleted and have been
inserted (observing correct polarity ±) into the battery
compartment.
3. If using rechargeable batteries, make sure the batteries
are suciently charged and that the battery switch is set
appropriately.
4. If you experience a howling or squealing sound, this is called
feedback. Depending on the earphone or headphone used, you
can sometimes get feedback when the volume control is turned
higher than 3 or 31⁄2.
To reduce feedback, turn down the volume, or move the
microphone (internal or external) farther away from the
earphone or headphone.
Also, try turning the Tone Control down (counter-clockwise)
to reduce the high frequency.
5. The Pocketalker headphone jack is a stereo jack, designed for
use with stereo earphones or headphones. However, if you use
mono earphones or headphones with the Pocketalker, turn the
balance control (located in the battery compartment) fully to the
left, or “mono” position. While this maximizes volume, this will
also help in maximizing battery life.
6. Observe what the LED indicators on the unit are doing:
Power ON LED (on front)
Charging LED (on right side)
T-Coil LED (on right side)
See the chart under “LED Indicators” to determine unit status
and problem resolution.
7. If the steps above don’t solve the problem, contact your
Williams Sound Dealer for further instructions.
