31 press ./ CLEAR and enter the correct frequency. If the dual entry is intentional, press ENT to accept. 5. By default, the scanner will configure the channels you enter for a two second delay after a transmission is received. This is indicated by D appearing in the top row of the display. If you do not want the scanner to pause for reply traffic before resuming scanning operation, press FUNC then 2/DLY until D is not visible in the top line of the display. STORING TEXT TAGS You can customize your scanner by storing text tags (up to 16 characters) for easy identification of channel transmissions. 1. Select channel using SCAN, ^, and v. 2. Press to move to the character you want to change. For example, to identify amateur (ham) radio transmissions in the 6 meter range, input HAM 6m as follows: 20-515Change01_04.fm Page 31 Friday, January 16, 2004 1:14 PM

33 DELETING FREQUENCIES FROM CHANNELS In certain circumstances you may wish to completely clear the contents of a channel. One example would be to create empty channels in a selected channel storage bank so the frequency copy function has empty channels available for copied frequencies. 1. Repeatedly press FUNC, and then CAR until MAN, Bank and the channel number appears. 2. Use the number keys and press SCAN to select the channel with the frequency you want to delete, or use ^ or v to navigate to the desired channel. 3. Press 0 and then ENT. The frequency is cleared, 0.00000 appears in the display. Clearing All Channels1. Set the scanner to the conventional channel mode so MAN, Bank, and a channel number appear. 2. Press and hold ./CLEAR. Then press 0. All 500 Channels Clear? Press 1 key ->YES Other key -> NO appears. 3. Press 1 to clear the all channels, or press any key other than 1 to cancel the clear. 20-515Change01_04.fm Page 33 Friday, January 16, 2004 1:14 PM
34 INITIALIZING THE S CANNER If you want to clear all the scanner’s memory, initialize the scanner. ! 1. Press and hold FUNC for about 2 seconds. 2. Press 8, 5, and then ENT. Do not turn off the scanner until the initialization is complete. SCANNING CHANNELS 1. Set the scanner to the conventional channel mode so MAN, Bank, and a frequency appear by pressing FUNC then CAR. 2. Turn SQ fully counterclockwise and adjust VOL to a comfortable level. 3. Turn SQ clockwise until the rushing sound stops. To begin scanning channels or to start scanning again after monitoring a specific channel, press SCAN.Ô To change the scanning direction, press ^ or v while scanning. To restart scanning while the scanner is in stop mode, press ^ or v . The scanner scans through all channels (except those you have locked out) in the active channel storage banks (see “Turning ! IMPORTANT ! Initializing the scanner clears all information you stored in the scanner’s memory. Initialize the scanner only when you are sure . Ô NOTES Ô The scanner will not enter scan mode if there are no frequencies stored in channels, or if all channels are locked out in the channel storage bank(s) that you are attempting to scan. In either of these cases, the scanner will display All channels Locked out!. See “Storing Frequencies Into Channels” on Page 30 If SQ is adjusted so you always hear a rushing sound, the scanner will not scan properly. Rotate the SQ control until the rushing sound stops. If SQ is adjusted precisely at the threshold where the rushing sound stops, the radio will be most sensitive to very weak signals. The radio may also receive unwanted noise or signals that are too weak to understand. Most users prefer to position the SQ control a little bit past the point of threshold to avoid receiving noise or signals that are too weak to understand. 20-515Change01_04.fm Page 34 Friday, January 16, 2004 1:14 PM
35 Channel Storage Banks Off and On” on Page 35 and “Locking Out Channels or Frequencies” on Page 51). Turning Channel Storage Banks Off and On To turn off channel storage banks while scanning, press the banks number key so the banks number disappears. For example, to turn off bank 1, press 1. The scanner does not scan any of the channels within the banks you turned off. To turn on channel storage banks while scanning, press the number key until the banks number appears. For example to turn bank 1 on again, press 1. You cannot turn off all channel storage banks. There must be at least one active channel storage bank. You can manually select any channel in a channel storage bank, even if the bank is turned off. Monitoring a Single Channel You can monitor a single channel with your scanner by navigating to that channel while in manual mode. The scanner will receive traffic on the selected frequency. To monitor a single channel, repeatedly press SCAN during conventional channel operation. MAN appears. 20-515Change01_04.fm Page 35 Friday, January 16, 2004 1:14 PM
36 Power Save CircuitYour scanner features a power save circuit that is automatically activated any time you manually select a channel or car number frequency. The power save mode works by allowing the receiver to sleep briefly while waiting for a call on the selected channel. USING CTCSS When your scanner stops on a frequency that is configured for CTCSS, it checks for a match between the transmitted CTCSS (quiet) code and the code that is stored with the channel memory. If the transmitted and stored codes match, the scanner stops on the transmission and allows the audio to pass to the speaker. If the codes do not match, the scanner resumes scan operation. If the special search code is in use, the scanner will instantly display any detected CTCSS mode. You can store the detected code into the channel memory by pressing ENT while the code is displayed. PROGRAMMING C HANNELS FOR CTCSS CTCSS allows you to program frequencies into your scanner that are used by more than one group in your area and listen only to the group that is of interest to you by specifying the group’s specific CTCSS code. CTCSS can also help reduce instances where interfering signals cause your scanner to stop on one channel. 20-515Change01_04.fm Page 36 Friday, January 16, 2004 1:14 PM
37 There are two ways you can program your scanner to operate with CTCSS. If you know the CTCSS code that is used on a particular frequency, you can manually enter the code when you are programming the scanner, or any time afterwards. You can also set a special search code up that will instantly decode the CTCSS code on a received transmission. Channels programmed with the search code will receive all traffic on the channel, and will instantly decode and display any CTCSS code that is found with the transmission. You can then store the found code in the channel memory with one keystroke. Programming a Quiet Code into a Channel 1. Select the channel you want to program the quiet code.Ô 2. Press FUNC, and then press
38 TURNING ON OR OFF THE CTCSS 1. Select the channel or the car number frequency. 2. Press FUNC then 4/CTCSS. The scanner turns on or off the CTCSS in the selected channel (or the car number frequency). Finding the Quiet Code on a Frequency 1. First, select the frequency of the car number or enter the frequency on which the quiet code is used into a channel. See “Storing Frequencies Into Channels” on Page 30. 2.

If you want to enter the detected code into the car number or the channel, press ENT while the code flashes. Using CTCSS During a Search You can find the quiet code on frequencies during a search (except SR1 and SR4). While searching through a band, press FUNC then 4/CTCSS. CT00:SRCH appears. When the scanner finds a frequency with a quiet code, the quiet code frequency flashes. To turn off the CTCSS feature, press FUNC then 4/CTCSS again. SEARCHING AND TUNING FINDING AND STORING A CTIVE FREQUENCIES You can search for transmissions using the scanners preprogrammed search banks. The search banks include six preprogrammed search ranges, SR0 to SR5. You can change the search range of Bank SR6 manually by setting the lower and higher ends of the search range.Ô Ô NOTES Ô You can use the scanners delay feature while searching the search bank. See “Delay” on Page 50. You can set CTCSS when searching any search range, except for SR1 and SR4. The scanner will display detected CTCSS codes depending on the CTCSS setting. See “USING CTCSS” on Page 36. The scanner does not search locked-out frequencies while searching ranges. See “Locking Out Channels or Frequencies” on Page 51. 20-515Change01_04.fm Page 39 Friday, January 16, 2004 1:14 PM
40 SEARCHING A P REPROGRAMMED F REQUENCY RANGE The scanner contains these preprogrammed search ranges, stored in the search banks (SR0- SR6). 1. Repeatedly press SRCH/PAUSE to select the desired search bank. 2. In the marine and FRS/ GMRS/MURS bands, you can directly select a channel or search through the band. When M appears at the left most position of the second line or the scanner stops on a frequency, you can directly select a channel (refer to “Search Band Charts” on Page 42). Use the numeric keypad to select a specific two digit channel number (for example, press 16 to select Channel 16, or 05 to select channel 5). You can also change the channels by pressing ^ or v.
