71 Searching and Storing 2. Turn the scroll control until Search and Store appears, then press E to select it. 3. Turn the scroll control until the system where you want to store the frequencies appears, then press E to select it. Note: You cannot select a racing system. If no systems are programmed, or all systems are locked out, No System Stored appears. Storing a System You can store frequencies into the system you selected in “Selecting a System”. Otherwise, the scanner stores frequencies in a new group it creates. 1. Follow Steps 1-3 under “Selecting a System”. A search option appears. 2. Turn the scroll control until the type of search you want appears, then press E to select it. A search band appears. If all systems are locked out, All Locked! appears and the scanner does not store any frequencies. When you select a search range, the scanner looks for active frequencies within that range and Search and Store appears on the display’s lower line and the system name and search range name appear on the display’s upper line. When the scanner finds an active transmission, it checks to see if the frequency has already been stored in the system. If the frequency has already been stored, the scanner continues to search. If the frequency has not been stored, it stores the frequency into a group named FOUND CHANNELS, then resumes searching. The scanner creates this group if it does not already exist.

72 Using the Close Call Feature Using the Close Call FeatureYour scanners Close CallTM feature lets you set the scanner so it detects, displays the frequency of, and lets you hear a nearby strong radio transmission. You can set the scanner so the Close Call feature works in the background while you are scanning other frequencies, turn off normal scanning while the Close Call feature is working, or turn off the Close Call feature and use the scanner normally. You can set the scanner so it alerts you when the Close Call feature finds a frequency. You can also set the frequency band where you want the scanner to look for transmissions. To turn Close Call detection on or off, press then . When the feature is on, appears on the display and normal operation is briefly interrupted about every 2 seconds. Notes: • The Close Call feature works well for locating the source of strong local transmissions such as mobile and handheld two-way radios in areas with no other strong transmission sources. Several factors affect Close Call performance, however. Performance is increased with higher transmit power, receive antenna tuned to the target band, and a low background RF level. Other than the antenna, you have no control over these factors, but they explain why performance might vary by both location and time. • The Close Call feature cannot detect satellite dishes or any transmitter with a frequency above or below the frequency ranges listed under “Setting Close Call Options” on Page 73. • The Close Call feature works better with some types of transmissions than others. It might not correctly display frequency information for transmitters using a highly directional antenna (such as an amateur radio beam antenna) or if there are many transmitters operating at the same time in the same area.

80 Using Weather Alert (SAME) Using Weather Alert (SAME)Your scanner has been primarily designed to be a radio scanner. While it incorporates weather alert as one of its features, we strongly recommend that you not use the scanner as your sole means for receiving emergency alerts. Your local electronics retailer carries several weather radios specifically designed for this function. Your scanner allows you to search for a local NOAA weather broadcast and set it to alert when a SAME weather alert is broadcast on a NOAA channel. You can also program SAME codes into the scanner and set a weather channel as a priority channel. In the following sections, you can also access the weather menu from Hold mode by holding then pressing Wx. Searching For a Weather Broadcast J 4 WX OPERATION J E J Weather Scan JE The scanner starts scanning the preprogrammed weather frequencies, and stops on the first signal. If this station is weak, rotate the scroll control to check for other weather broadcasts in your area. Note: NOAA broadcasts are continuous broadcasts. You will only lose reception if you move out of a coverage area. If the signal is lost, the scanner resumes searching for a weather transmission. Turning Weather Alert On/Off 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 holds on the weather channel, but does not play the channel’s audio. If it detects a weather alert, it sounds a tone, displays information about the weather alert, and turns on the audio so you can hear the weather broadcast.
