Uniden UBC 175xL - Manual (Page 5)

ANTENNA
The telescopic antenna provided with the Uniden® Bearcat® 175XL is recom­
mended for most monitoring. Insert the antenna swivel connector into the anten­
na jack located on the back panel (fig. 1). Extend the antenna. The swivel con­
nector allows the antenna to be angled if desired. For weak signal reception
or electrically noisy locations, an external antenna may be helpful.
You can also store your antenna in the handy compartment located under the
unit. Simply remove the antenna from the connector and snap it in place. When
you are ready to set it up again unsnap the antenna and plug it in.
CONTROLS
1 On-Off/Volume: Turns the receiver power on or off, and also varies the
audio output level (fig, 2).
2. Squelch; Eliminates the annoying “rushing" sound that is present between
transmissions when no signal is being sent. Proper setting of this control
keeps the receiver'‘quiet” and allows scanning until a signal is received
(fig. 2 ) . The 175XL also has an automatic squelch setting marked "AUTO”.
Turn the squelch control to “AUTO” for a preset level that allows all clear
signals to be received.
