Helpful Hint:
The LED headlights can be used as a low battery indicator.
Their brightness is regulated when the battery is good, but
as the battery is depleted, a point will be reached where the
brightness of the LEDs will begin to decrease. It is a good
idea to consider replacing the battery at this time (or at least
have a spare one on hand). The HOUND 3 will continue to
work for a while, but some reduction in sensitivity and loss
of loudness may be noticed. Replace the battery for maxi-
mum performance.
6.2: Power Button (E)
The Power Button is typically pressed and held while the
HOUND 3 is being used. When pressed, the Amplifier and
Speaker is activated, and the LED headlights are turned on.
Release the button to turn the product off.
6.3: LED Signal Strength Indicator (D)
The Signal Strength LED is used to indicate the presence of
a signal when it may be difficult to hear the signal coming
from the speaker (because of high ambient noise levels). It
will glow brighter as the received signal strength increases.
The brightness will be seen to pulsate with the characteris-
tics of the received signal.
Helpful Hint:
The Signal Strength LED responds to any received signal.
Any sound normally heard in the speaker will cause the LED
to light. The user will note that the HOUND 3 will “pick up”
signals from electrical devices other than the FOX or FOX 2.
