HINTS & TIPS
The POCKETALKER™PRO has
been designed to be as easy to use
as possible. However, if you have
trouble, check the following:
1. Make sure the microphone is
plugged into the “MIC” jack and
the earphone or headphone is
plugged into the “EAR” jack.
2. Make sure the batteries are
not depleted and have been
inserted correctly into the battery compartment.
3. If rechargeable,make sure the
batteries are sufficiently
charged.
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 3
1
⁄2.
www.ActiveForever.com
19
To eliminate feedback, turn
down the volume control or
move the microphone further
away from the earphone or
headphone.
5. The POCKETALKER
™
PRO earphone jack is a mono jack,
designed for mono earphones
and headphones. If you use
stereo earphones or headphones
with the POCKETALKER
™
PRO,
only one side of the headphones
will work.
6. If the steps above don’t solve
the problem, contact your
Williams Sound Dealer for further instructions.
