To turn off the priority feature, press PRI- ORITY. PRI disappears.

Note: If you are scanning more than one bank in which a priority channel has been programmed, the scanner stops on the lowest-numbered priority channel first while scanning.

LISTENING TO THE

WEATHER BAND

The National Oceanic and Atmospheric Administration (NOAA) uses 7 frequen- cies to broadcast local forecasts and re- gional weather information. We have preprogrammed your scanner with these frequencies.

Note: For a list of all 7 national weather frequencies, see “National Weather Fre- quencies” on Page 22.

To scan the preprogrammed weather channels, press WX. WX appears, and the scanner searches the weather chan- nels and stops on an active broadcast. If a broadcast is weak, press WX again to continue searching through the weather channels. Press ▲ or ▼ to switch the search direction.

Weather Alert

Your scanner’s weather alert feature can warn you when your local weather sta- tion broadcasts a severe weather emer- gency signal. (See “Testing Alert Tone”).

1.Press WX to find the clearest local weather broadcasting station.

2.Press ALERT. ALT appears and the broadcast turns off.

When a severe weather emergency sig- nal is broadcast, the scanner sounds a loud alarm (regardless of the volume control setting), and H appears and ALT flashes. The alarm continues until the emergency signal stops transmitting.

To manually turn off the siren and exit the weather alert mode, press ALERT.

Testing Alert Tone

To hear the alert tone, make sure the scanner is not set to sound an alert tone, press WX, then hold down ALERT. The tone sounds and the frequency and TESt alternately appear.

Press ALERT to exit the alert tone mode.

TURNING THE KEY TONE ON OR OFF

The scanner is preset to sound a tone each time you press any of its keys.

Follow these steps to turn the scanner’s key tone on or off.

1.If the scanner is turned on, turn VOLUME counterclockwise until it clicks to turn it off.

2.Hold down S/S-LOCKOUTwhile you turn on the scanner. no bEEP (if the key tone is off) or On bEEP (if the key tone is on) appears for about 3 seconds.
