HINTS & TIPS
The POCKETALKER®ULTRA 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 “EARPHONE” 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
21
turned higher than 3 or 31⁄2.
To eliminate feedback, turn down
the volume control or move the
microphone further away from
the earphone or headphone.
Also, try turning the Tone Control
down (or counterclockwise) to
reduce the high frequency.
5. The POCKETALKER
®
ULTRA earphone jack is a mono jack,
designed for mono earphones
and headphones. If you use
stereo earphones or headphones
with the POCKETALKER
®
ULTRA,
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.
