CAUTION!
Danger of hearing damage!
If you switch the squelch off or adjust the squelch
threshold to a very low value, loud hissing noise can occur
in the receiver. The hissing noise can be loud enough to
cause hearing damage!

Always make sure that the squelch is switched on.

Before adjusting the squelch threshold, set the
volume of the headphone output
PHONES
to the
minimum (see page 21).
