Birdie Frequencies; Scanning Stored Channels - Uniden PRO505XL Manual

SCANNING STORED CHANNELS

• If the scanner displays -dUPL-, the frequency is
already stored in another channel. Press ENT if
you want to continue storing the frequency. Press
TUNE/CLEAR to cancel.
• If there are no empty channels in the bank,
Ch-FULL appears. You can select another bank
or clear some channels in the current bank (see
"Clearing a Stored Channel" on page 18).
• If the scanner displays -dUPL- or CH-FULL, you can
store another channel location by pressing PGM.
The channel number flashes and 000.0000 (or
previous frequency) appears. Press the desired
channel number then press ENT. Repeat if
needed. Press ENT again when an empty channel
is found.
Scanning Stored Channels
Press SCAN/MAN until SCAN appears to
continuously scan through all channels with stored
frequencies.
If the scanner finds an active frequency, it stops and
displays that channel and frequency number, then
it automatically begins scanning again when the
transmission on that frequency ends.
• Press  or  to reverse the scanning direction.
• To monitor a channel, press SCAN/MAN at any
time during the transmission so MAN appears.
The scanner does not scan channels in banks that are
turned off.

Birdie Frequencies

All scanners have birdie frequencies, which are
signals created inside a scanner that can cause
interference.
To find the birdies in your scanner:
1. Disconnect the antenna, and make sure that no
other nearby radio or TV sets are turned on near
the scanner.
2. Search every frequency range from its lowest
frequency to the highest. Occasionally, the
searching will stop as if it has found a signal,
often without any sound. This is a birdie.
3. Make a list of all the birdies in your scanner for
future reference.
