This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when altered to receive them. The installation, possession, or use of this scanning radio in a motor vehicle may be prohibited, regulated, or require a permit in certain states, cities, and/or local jurisdictions. [. . . ] Note: Because there are many different frequencies allocated to fire and police departments, it can take several minutes to search all the service frequencies. Storing Frequencies into Channels During Service Search You can store frequencies you found during service search or service search hold mode into channels. Press Func and Pgm during service search or service search hold mode. The frequency and the lowest blank channel alternately appear. Press E to store the frequency into the blank channel. If you want to select another channel, press Func + or Func + before you press E. You can also use the 0-9 key to select the bank. If you entered a frequency that has already been entered elsewhere, the scanner sounds an error tone and displays the channel that was duplicated. If you entered the frequency by mistake, press then enter the correct frequency. To enter the frequency anyway, press E to accept. Scanning the Stored Channels To begin scanning channels, press Scan. The scanner scans through all non-locked channels in the activated banks. (See "Locking Out Channels" on Page 48 and "Turning Channel-Storage Banks On and Off" on Page 47).

Notes: · · If you have not stored frequencies into any channels, the scanner does not scan.

To listen to a weak or distant station, turn Squelch counterclockwise. To ensure proper scanning, adjust Squelch until the audio mutes. · Manually Selecting a Channel You can continuously monitor a single channel without scanning. This is useful if you hear an emergency broadcast on a channel and do not want to miss any details - even though there might be periods of silence - or if you want to monitor a specific channel. To manually select a channel, press Hold, enter the channel number then press Hold again. Or, during scanning, if the radio stops at a channel you want to listen to, press Hold once. (Repeatedly pressing Hold at this time causes the scanner to step through the channels. ) Press Scan to resume automatic scanning.
