GENERAL DESCRIPTION

Scanning is easy and fun with the Uniden® Bearcat® 175XL. Advanced elec tronics provide programmable operation and dependability. The rubber keytop keyboard has been designed for comfort and operating efficiency. It is divided into two sections: PROGRAM, which allows you to command any frequencies (VHF/UHF) on its 16 channels; and OPERATION. Volume and squelch levels are controlled by smooth acting knob adjustments. An 8-digit, back-lighted LCD display provides frequency, channel, lockout, delay, priority, weather search and memory loss information, A unique capacitor type memory back-up eliminates the need for batteries. The case is constructed of high impact plastic.

MEMORY BACK-UP

The Uniden® Bearcat® 175XL is equipped with a unique capacitor type memory back-up. The capacitor back-up will provide approximately four hours of memory retention in the event of a power interruption. When memory loss has occurred, the memory loss message will be displayed. It wilt remain on the display until any operating key is pressed. The system is completely automatic and requires no maintenance.

INSTRUCTIONS OPTIONAL ANTENNA

An external antenna may be helpful in fringe areas. Always use 50-70 ohm coax ial cable for lead-in. For lengths in excess of 50 feet, RG8AU low-loss foam dielectric coax is recommended. Your scanner is equipped with a standard automotive type antenna connector. A mating plug (optional) must be used.

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.
