LIQUID CRYSTAL DISPLAY

The Uniden@Bearcat'" 50XL is equipped with a custom designed liquid crystal display to indicate channel number, frequency and lockout mode. All LCDs have a preferred viewing angle where the display contrast is maximum. The best viewing angle depends on design consideration, temperature and battery con- dition. Optimum viewing of the Uniden@Bearcat'" 50XL isachieved by holding the unit at about 45 degrees. This also provides the best position for using the

keypad.

Page 7

CAUTION:Because of inherentlimitations,liquidcrystaldisplaysshouldnotbe

subject to extremes of temperature or humidity. If the unit is exposed to

temperaturesbelow - 20°C (- 5°F) or above +60°C(+ 140°F),thedisplay

may temporarily cease to function properly, and in some cases permanent

damage may result. It is, therefore, recommended that the radio not be sub-

jected to extreme

OPERA TION

Now that you are familiar with the controls and their functions, you are ready to use your scanner. The following instructions illustrate the operation of your

Uniden(i)Bearcat(i)50XLPleasereadeachsectionthoroughlybeforeattempt-

ing to program your scanner. Each section explains a function and then shows the key strokes involved in that function.

NOTE: If you know the exact frequencies you wish to scan, proceed with the

"PROGRAMING" section. If you do not know the frequencies (i.e., police, fire, weather, etc) you wish to scan, check with your dealer. Uniden also makes frequencies available in its Betty Bearcat Frequency Directory and Local Fre- quency List See the order forms packed with your unit

KEYPAD LOCK

Located on the front of the unit is the keypad lock switch. This switch turns the keypad on or off. Whenever you operate your scanner, this switch must

be in the "ON" position in order for the keypad to work. After all programing and operations are complete, turn this switch to the "OFF" position to avoid any misprograming or accidental entry.

PROGRAMING YOUR SCANNER

Turn the unit on and Press IMANUAL I key to remove scan mode. then press

the DJkey followed by the I MANUAL I key, This will bring the scanner to

channel 1 in the manual mode. Press the number keys for the desired frequency. Remember tp press the Dkey whenever there is a decimal point in the frequency,

A decimal point is indicated in the frequency as a "- ",As each key is pressed., the display will show that digit. If you forget the previous digits pressed, press the I REVIEW I key to review the frequency at any time to confirm that it is

SCAN

To scan the channels programed in memory, press the ISCAN Ikey. The chan-

nels will automatically scan at the rate of approximately 15channels per sec- ond. As the unit scans, the channel digits in the display will advance rapidly, indicating the scanning mode. In order to stop the scan mode, a transmission must be present on one of the programed frequencies The squelch control must also be set so that the transmission will "break squelch" and stop the

scan. You can also stop scanning by pressing the IMANUAL Ikey.

SCAN DELAY The Uniden@ Bearcat@50XL is automatically programed to pause for about

3 seconds after a transmission ends on any channel. This is useful in prevent. ing the continuation of scanning when there is a slight pause in transmission. It is also useful when both sides of a conversation are occurring on the same channel. This automatic delay is built intoeverychannel andcannot bechanged.

ERRORMESSAGE To inform the user anytime an out-of-band frequency is stored in memory,

the BC 50XL automatically displays HE" in this event. The condition may arise when the user presses ENTER with an invalid number in the display. The user should simply enter an in-band frequency (see programming section) to clear the ERROR indication.

BATTERY LOW INDICATION Your scanner has a unique power-saving battery Iow indicator. When

a special circuit detects that the batteries are getting Iow, a beep

will sound if the unit is on. The beep tone will continue every 15

seconds until the batteries are completely dead. The memory will be maintained until batteries are dead-

Page 10

WARNING.. When you first hear the beep toae, you should turn the unit off and immediately replace your batteries (or recharge if NiCad batteries are used) to avoid losing memory. When you replace weak batteries, you must install the new ones immediately to keep the sca- nner memory. Be sure to read the "Installing Batteries" section of this guide before attempting to replace your batteries.

HELPFUL HINTS

The following hints areprovided to help you get the most out of your newscan-

ner. By reading this entire guide, including this section, you will better under- stand and enjoy your new Uniden(ii)Bearcat(ii)50XL.

1. Always remember to press the enter key when programing a frequency. If theenter key is not pressed the frequency will not be programmed into that channel. Itisagood idea to press the review key after entering a frequency to confirm that the correct number was entered.

2. If you ever have to ship the unit. be sure to remove the antenna and place it and the unit in the original styrofoam inner packing and box. One of the most common causes of damage to electronic products is improper pack- ing when shipping.

3. Remember that the liquid crystal display is subject to permanent damage if it is exposed to extremes in temperature or humidity. Take extra care with your scanner in the winter and on sunny, summer days.

4. The Uniden(ii)Bearcat(ii)50XL never sleeps-its memory is always active

even though the power is turned off. Battery drain in the off mode is almost as Iow as the discharge rate of the batteries alone. As long as you observe the battery Iowindicator and act accordingly, you shouldn't have any prob-

lem with memory loss.

5. Receiver sensitivity is affected by the location of the antenna and the en- vironment that the unit is used in. Best reception will occur when the unit is placed on a level metal surface with the antenna pointing up. Placing the unit close to a window will also provide better reception.

6. Receivers, such asthe Uniden@Bearcat(ii)50XL, which have broad tuning ranges are subject to interference from internally generated signals ("Bir- dies") on a few receiver frequencies. On these frequencies, reception of external signals may be impaired. Nothing is wrong with your scanner if this kind of interference occurs, unless it happens on a large number of frequencies.

FREQUENCY ALLOCATIONS

Because of the short-range nature of VHF and UHF FM communications, fre- quencies allocated to services in one geographical location will not be heard more than 25-50 miles distance (an exception is "skip", when signals bounce back to earth from the ionosphere). For this reason, aseparate frequency direc- tory must be compiled for each monitoring area. Most standard frequency separations and classifications are regulated in the United States by the FCC.

Block allocations...and even some discrete frequencies...covered by your scan- ner are shown below. These are not necessarily active in your area.
