ANTENNA

The telescopic antenna provided with the Uniden@ Bearcat@ 175 XL 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.
