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

Helpful Hints

The UBC 70XLT is a high quality electron
ic radio receiver. The following hints should
help you understand and enjoy your unit.

1. Make sure the unit is turned off before
disconnecting the power. You may want to
record the programmed frequencies before

power is imciTupted in case memory is
lost.

2. If memory is lost, simply reprogram
each channel. Memory loss will be in -

dicaied by unfamiliar frequencies in each
channel.

3. If strong interference or electrical noise

is received, you may need ю relocate your
scanner. A higher elevation such as the se ­cond floor may provide better reception.

4. Whenever the keypad is used it is impor -

lant to press firmly on the center of each
key.

5. Do not use the scanner in high moisture

environments such as the bathroom or kil ­chen. Avoid placing the unit in direct sun -

light or near heating elements or heating
vents,

1. Every 2 - 3 months the scanner should

be left on to drain all battery power. Be

sure to write down the programmed
frequencies for reprogramming when
batteries are recharged,

2. Recharge the batteries overnight to
insure a full charge.

3. Do not leave the charger plugged in for
long periods of time. Do not recharge the
unit unless needed.

Birdies

All radios are subject to receiving undesired
signals. If the UBC 70XLT stops during
scan mode and no sound is heard, it may be

receiving a "Birdie”. Birdies are internally

generated signals inherent in the electro -

nics of the receiver. Press the Scan key to

continue scarming.

6. Clean outside cabinet with mild deter ­gent. Do not use abrasive cleansers or sol ­vents. Be careful not to rub LX3D window
area.

7. There are no user serviceable parts inside
with the exception of the battery pack. Do
not attempt any repairs except replacing
batteries.
