Introduction

Welcome...

[o the exciting world of hand-held radio
scanners. State-of-the-art enginceririg and
microelectronics provide programmable
operation and depertdability in such a small
unit. The keyboard has been divided into
two parts; PROGRAM, which allows you to
command any frequency (VHFAJHF) on all
20 channels; and OPERATION, which
controls Scan, Lockout, Delay, Priority,

Search, and Direct Channel Access . Vol ­ume and squelch levels are controlled by
precision thumb wheel adjustments. An

LCD display provides frequency and oper -

ation information. Rechargeable NiCad
batteries provide hours of monitoring and
recharge quickly overnight. The case is
constructed of high impact ABS plastic and
metal to provide years of trouble-free use.

Please read this guide tlioroughly before

attempting to operate the unit.

WARNING!

Santronic does NOT represent this unit to

be WATERPROOFED. To reduce the risk

of fire, electrical shock or damage, do not

expose this unit to rain or moisture.

Please keep the shipping carton and pack ­ing materials. This carton serves as an
excellent method to transport the scanner.

Rechargeable Batteries

'[’he UBC 7ÜXLT comes with a recharge
able NiCad battery pack. When fully

charged this power supply will provide hours of

dependable use. When the batteries become
low simply plug the AC Adapter/Charger
into the jack on the side of the unit and
charge over night. The scanner can be
operated while charging. It is important to
periodically allow the batteries to discharge
completely, to maintain full operating
capability. See the Battery Maintenance
section of this guide.

To replace the battery pack, slide the
battery door down and off the back of the
unit. Unplug the old battery and connect

the new one. Be sure to charge the scanner

overnight before operating the unit.

See the Optional Accessories section for

replacement battery information.

External Antenna

Unpacking

Carefully remove all items from the ship

ping canon. If there is any visible damage
or any item appears to be missing, notify

your dealer immediately.
The following items are included with your

UBC 70X1.4':

* Uniden Bearcat Scanner
* Carrying Case
* Flexible Rubber Antenna
* Earphone
* Operating Instructions

*

(read carefully and save)

The UBC 70XLT is designed to be used
with the flexible rubber antenna (included)
but may also be used with an external antenna.

You may find an external antenna to be

helpful in fringe areas or for mobile use.

Always use 50 - 70 ohm coaxial 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 BNC eormecior. A mating plug
(optional) may be necessary for external
antenna connection.

Antenna Installation

The flexible rubber antenna provided with
your unit is recommended for most moni ­mring. Insert the connector into the an ­tenna jack on the top of the unit and twist
to lock. For weak reception or electrical
interference, a different location may be
helpful. An external antenna may also
provide better reception.

External Power

Controls and Functions

The UBC70XLT can be powered by the
Charger (included with the unit which con
verts standard household current into 12
VDC. Plug charger into the jack on the side
of the unit. Plug the other end into any
standard 220 VAC household outlet. Do
not plug the scanner into an outlet con
trolled by a wall switch as prolonged peri
ods of no power will cause a loss of memory.

CAUTION: Use only the Charger included
with your UBC 70XLT or Cigarette Lighter
Power Cord UA502 or UA502A. Recharg
ing or operating with a higher voltage or re
verse polarity may damage your unit.

The UBC 70XLT may also be used with any

1 2 VDC power .source such as a vehicle.

Sec the Optional Accessories section for

more information.

Controls and Functions

1. Power On/OIT- Select “ON” to operate
scanner. Be sure lo turn the unit off when
not in use.

2. Volume Control - Side mounted thumb
wheel to adjust the desired volume.

3. Squelch Control - Eliminates the
annoying "rushing" sound heard between
transmissions when no signal is being
received. Proper adjustment of this control
keeps the receiver quiet and allows scan ­ning until a signal is received.

4. Keypad - Locks the numeric keypad to
avoid accidental mis-programming. Select
"ON" to unlock and "OFF" to lock .

5. Light - Press to illuminate the LCD
display for night time use. The display
light requires a minimum amount of
battery power; consequently, it should be
used sparingly. The light will automatically

turn off after 15 seconds.

6. Numeric Keypad ("0-9" and ".") - Used
to program all frequencies into memory and
for direct channel access,

7. Enter - The "E" is used to enter frequen -

cies into the scanning memory,

8. Scan ■ Press to start scanning all fre
quencies programmed in memory.

9. Manual - Press to stop scanning. Press
to .step to the next channel. Dial the chan ­nel number and then press the manual key
lo go directly to that channel.

10. Lockout - Press to lock out the
reception of frequencies on selected
channels during scanning. Lockout is
retained in memory. Press again to delete
the Lockout function.

11. Delay - Press to add a 2 second delay to
the end of a transmission to avoid missing
call-backs.

12. Priority ■ Press to sample the activity
on channel 1 every 2 seconds regardless of
other operational settings. If a transmis -

sion is found the scanner will monitor

channel 1 until no signal is present.

13. Search - Press to search for new active

frequencies wiiliin preset ranges of any
band.

14. Limit - Enter the low and high limits

of the search range. Press to manually step
the search frequency down.

15. Hold - Press to stop and hold the
search function on the current frequency.
Press again to manually step up to the

prcceeding frequency.

urriden

The UBC 70XLT has 20 memory channels,
each of which can be programmed to store
one frequency. When “SCAN” is pressed,
each of the programmed frequeneies will be
sampled for a transmission (locked channels
will be skipped) at a rale of about 15 chan
nels per second. If an active frequency is
found the unit will stop and monitor that
frequency until there is no longer any activ
ity. A 2 second delay can be added to each
channel and will allow the unit to monitor
the frequeney for a return or continued
transmission. If, after 2 seconds, the fre
quency remains inactive, the scanning cycle
will resume.

When the unit is first turned on, each chan ­nel will contain a test frequency or
"000.000“. When new frequencies are
programmed the old will be erased. If an
invalid frequency is entered, "Error" will be
displayed and the old frequency will return.

Operation

To operate the scanner make sure that the

batteries are fully charged or power is
supplied to the unit. Turn the Volume
control on and adjust the desired level.

Adjust the Squelch by turning the knob
counter-clockwise until a "rushing” so
und is heard. Turn the knob back until
the receiver is silent. After the channels
have been programmed, operation is
simple. Press the Scan key to scan all the
channels. Press the Manual key to stop
scanning.

LCD Display

The UBC 70XLT has an LCD display
which shows the current channel and fre
quency as well as other operational modes.
When the unit is scanning, the channel num
ber will rapidly advance while the frequency
display will go blank. When the scanner is
stopped the current channel and frequency
will again be displayed.

When frequencies are programmed the dis ­play will show the digits as they are
entered. The display will also show "PRI"
when the Priority mode is on, "L/O" when ­ever a channel appears that has been locked
out, and “DLY" whenever a channel has
been programmed for delay. "ВАТТ" will
Bash when the batteries need to be
recharged.

Programming

To program a frequency into a charmel,
press the digits of that frequency including

the decimal point and then, press the Enter
key. If an invalid frequency is entered, the
display will show "Enor" and then, return

to the original frequency. To change a
frequency enter the new one and the old one
will be erased.
