tomatically in the COMM (COM band), MR, and WX modes. It pauses on signals received, so you can talk to the station(s) on the frequency received. Scanning Channels 1. Set the transceiver to the COMM mode. 2. Press the [FUNC] key to display the Function screen. 3. Select SCAN on the screen by pressing the

[] or [] key, and then press the [ENT] key. The scanning starts and the display returns to the COMM mode screen. The SC icon appears on the display. After the signal disappears, scanning resumes. To stop scanning, press the PTT switch or select SCAN again in the Function screen. Note: When you enable the alarm function at recep-

tion of the weather alert signal via the COMM SETUP menu in the SETUP mode, the last weather channel will be watched as the every second frequency during a scan. Example: When the last weather channel is 162.400 MHz (WX02), the transceiver scans in the following order. 118.000 162.400 118.025 162.400 118.050 162.400 ... The frequency of the last weather channel, however, will not be displayed until the scanner encounters the weather alert signal. The scanner searches signals from the lowest fre-

quency to highest. When the scanner encounters a signal, the scan-

ning pauses and the transceiver remains on that channel until the signal disappears, and the fre-

quency indication on the display blinks. 32 FTA-250L OperATing MAnuAL sCannIng operatIon Scanning the Specified Channels Among the memory and weather channels, you may scan only those on which you want to see if a signal exists. Marking the channels 1. Set the transceiver to the MR or WX mode and tune to the channel that you want to be scanned. 2. Press the [FUNC] key. 3. Select MEMO MEM by pressing the [] or []

key, and then press the

[ENT] key. The current channel is marked to be scanned and the icon, which indicates that the channel is the target of scanning, will appear at the top side of the memory name when the display returns to the MR or WX mode screen. 4. Repeat steps 1 to 3 above to mark other channels as well. Scanning the marked channels 1. Set the transceiver to the MR or WX mode. 2. The scanning starts and the display returns to the MR or WX mode screen. The FTA-250L operates in the same way as it does when scanning all channels described in the previ-

ous page, except that it searches marked frequencies only. Note: When you enable the alarm function of the weather alert signal via the COMM SETUP menu in the SETUP mode, the last weather channel will be watched as the every second frequency during a scan. Example: When the last weather channel is WX02

(162.4 MHz), the transceiver scans in the following order. 001MEM WX02 002MEM WX02 003MEM WX02 ... The frequency of the last weather channel, however, will not be displayed until the scanner encounters the weather alert signal. 3333 FTA-250L OperATing MAnuAL setup mode Menu items MEMORY BOOK You may store the frequencies with a tag name to the memory of the transceiver, and maintain the stored entries.
