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
