after end of the transmission to wait for a possible reply. A Delay function can be set for each
programmed channel so that when searching stops on a channel there is a brief pause before
the scanning resumes. The delay can be set when your scanner stops on a channel while
scanning or when a channel is selected by Manual mode.

Weather Channel
The BC248CLT allows you to search from 7 pre-programmed NOAA channels for your local
NOAA weather channel.
Press WX/ALERTto find the active weather       
channel in your area. WXicon appears in the
display. It is possible that your area is covered by
more than one weather station.
When you press WX/ALERT, the BC244CLT immediately finds an active broadcast. If the
broadcast sounds weak and distant, press SCANto look for a closer station.
To exit Weather Channel Scan mode, press    
SCANNER, RADIO AM/FMor OFF.
Do not program a weather frequency into one of the 50 channels.
Because weather channels transmit continuously, the scanner remains
on that channel, disrupting the scanning cycle. The Weather Scan
feature is provided specifically to avoid this occurrence.
In some parts of the country, you may not be able to monitor weather
broadcasts, such as in low-lying areas. Normally a higher location
improves the reception.
All weather channels transmit continuous broadcasts. Once the
Weather Scan stops on a transmission, it remains on that channel.
Weather Scan does not resume automatically. You must press
WX/ALERTagain to resume weather scanning.

Weather Alert
In Weather Alert Mode, your scanner functions as a severe weather warning radio. This is
especially useful when your area is expecting severe weather conditions late at night. When
you set the scanner to Weather Alert Mode, it emits a loud siren whenever your local NOAA
weather station broadcasts a severe weather emergency tone.
1. Press WX/ALERTto find the active           
weather channel in your area. WXicon
appears in the display. It is possible that
your area is covered by more than one
weather station.
2. Press WX/ALERT again to select the        
Weather Alert Mode. The ALERTand
HOLDicons appear in the display. Your
scanner volume is muted until the warning
tone sounds.
Your scanner now functions as a Weather Alert radio, waiting to receive a severe weather
emergency tone. When your scanner receives the emergency tone from your local NOAA
weather station, it responds with a loud siren at maximum
volume (regardless of the volume
control setting). The siren will continue until the emergency tone stops transmitting.
To cancel the siren, press WX/ALERT.
To test the siren, set the radio to Weather Alert mode during your local
NOAA weather stations’ regularly scheduled testing period. 
Contact your local NOAA office to find out the exact date and time of
thetesting period.
