mA. You must use a power source that supplies 12V DC and delivers at least 500 mA. Your standard 12V car battery should be sufficient. The cord connector’s center tip must be set to positive and its plug must fit the scanner’s DC 12V jack. The supplied DC power cord meets these s pecifications. Using a power cord that does not meet these specifications could damage the scanner or the adapter. • Always connect the adapter or DC power co rd to the scanner before you connect it to the power source. When you finish, disconnect the adapter or DC power cord from the power source before you disconnect it from the scanner. • For added safety and to protect your scanner, disconnect the cable from your vehicle battery’s negative (-) terminal before you begin. Follow these steps to connect the DC power cord. 1. Connect the power cord’s black wire to a chassis ground, such as a metal screw attached to a metal part of the vehicle’s frame. Be sure that the screw is not insulated from the frame by a plastic part. 2. Connect the power cord’s red wire (with in-line fuse) to a source of voltage that turns on and off with the ignition switch, such as a spare accessory terminal in your vehicle’s fuse box. 3. Insert the power cord’s barrel plug into the DC 12V jack on the rear of the scanner. 4. Reconnect the cable to the vehicle battery’s negative (-) terminal. 12 ANT. EXT. SP. DC 12VREMOTE 12 13 Applying Power Using Standard AC Power To power the scanner from an AC outlet, use the provided AC adapter with a 5.5 mm outer diameter/2.1mm inner diameter tip. Caution: You must use a Class 2 power source that supplies 12V DC and delivers at least 500 mA. The cord connector’s center tip mu st be set to positive and its plug must fit the scanner’s DC 12V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter. • Always connect the AC adapter to the sca nner before you connect it to AC power.
When you finish, disconnect the adapter from the AC power before you disconnect it from the scanner. 1. Insert the adapter’s barrel plug into the DC 12V jack on the rear of the scanner. 2. Plug the adapter into a standard AC outlet. Note : Use only the AC adapter supplied with your scanner. Connecting an External Speaker In a noisy area, an external speaker (a vailable at a local electronics store) positioned in the right place might provide mo re comfortable listening. Plug the speaker cable’s 1/8 inch (3.5 mm) plug into your scanner’s EXT. SP. jack. Note: Connecting an external speaker disconnects the scanner’s internal speaker. Listening Safely • Do not use the earphone. The volume is not adjustable for the Warning Alert and damage to your hearing could occur. Connecting the Clone Cable You can transfer the progr ammed data to and from another 20-426 scanner using a RS232C Straight Cable (9 pin to 9 pin) (not supplied). Connect the cable between each scanner’s REMOTE jacks. See Clone Mode on page 49. You can also upload or download the programmed data to or from a PC using optional programming software available through your local electronics store. ANT. EXT. SP. DC 12VREMOTE 12V ANT. EXT. SP. DC 12V REMOTE 20-426 PM Page 13 Scanning Overview You can scan in one of four ways:
1. Highway Patrol Scanning When you select a state you want to scan in Highway Patrol mode, you can scan pre-programm ed Highway Patrol frequencies. 2. Service Scanning Press SVC to select one of the nine services to find an active frequency. 3. Band Search Select a frequency band to search. The Search function is different from scanning. It searches for any active fr equency step by step within the lower and upper limits of the band. When an active frequency is found, the scanner will stop and stay on that frequency as long as that transmission lasts. If that frequency is interesting to you, press HOLD/RESUME to hold the frequency on the display. Then program it into the private bank you want to store. If you do not want to program that frequency, press HOLD/RESUME or just wait until the transmission ends. The search resumes automatically 2 seconds after the last transmission and looks for more active frequencies. 4. Private Scanning If you have programmed frequencies into this bank, press PVT to scan only those that you hav e programmed in this bank. Note: Before you can scan the Private Bank, you must program frequencies into the channels. To program frequencies, see “P rogramming Frequencies into Channels” on page 21. When scanning stops on an active frequency, it remains on that channel as long as the transmission continues. When the transmi ssion ends, the scanner will remain on the same channel for 2 more seconds, waiting for a responding transmission. If there is no responding transmission within 2 seconds, the scanning cycle resumes. Turn the Scanner On 1. Turn the VOL knob clockwise. The scanner is turned on: the Alert Light flashes and the Alert Tone beeps loudly. Note: The Alert Tone depends on the currently setting selected (see page 17). 2. The last setting mode selected before starts. 14 VOL push ALERT

If the gate is too low (squelch too low), everything (all noise as well as signals) gets through. If the gate is set too high (squelch too high), nothing gets through. If the gate is set just right (squel ch set properly), just the desired signals get through. Setting the Squelch 1. To set the squelch, press HOLD/RESUME to stop scanning. If needed, adjust VOL until you do not hear a signal (see page 17). 2. Turn SQL fully clockwise until hiss heard. This lowers the “squelch gate, ” allowing all signals and noise to get through. 3. Turn SQL fully counterclockwise just until hiss stops. This raises the “squelch gate,” allowing only strong signals to get through. In the city, you may want to adjust the Squelch even further counterclockwise to decrease t he range of the Highway Warning Alert signal. This prevents the alert from sounding unnecessarily due to farther, less important sources.

When Highway Patrol scanning, the Highway Warning Alert is activated. Selecting the State 1. Press STATE to select the state you are operating in. Press and hold STATE to scroll rapidly. Hint: For the State Code Or der, please see page 56. 2. To step forward through the states (A - W), press STATE and, within three seconds, press the key repeatedly. To step backward through the st ates (W - A), press STATE and, within three seconds, press the key repeatedly. 3. To scroll rapidly, press and hold the or key. Scanning Highway Patrol Frequency You can scan Highway Patrol frequencies by pressing PVT or HWY/POL . 1. Press HWY/POL to scan through only pre-programmed Highway Patrol frequencies. or Press PVT repeatedly in Highway scanning mode until “ HWY/POL” appears on the display to scan through pre-programmed Highway Patrol frequencies. Hint: If you press PVT repeatedly in Highway scanning mode until “ HWY/POL ” and “PVT” appears on the display, you can mix-scan between Highway Patrol frequencies and User Programmed channels. 2. When the scanner receives communications, scanning stops, the state code and the frequency appear. When the transmission ends, the scanner holds for two seconds on that frequency fo r a response. For more information on the Delay feature, please see page 28. If there is no response, scanning resumes. 16
Page 16 17 Highway Patrol Scan Hold 1. When scanning stops on a desired frequency, press HOLD/RESUME to hold on that frequency as long as you like. When in the HOLD mode, press the or key to step up or down the frequency. To step up or down rapidly, press and hold the or key. If you change into a frequency which is a control channel, the scanner may display the Active ID (When TRUNK mode is active). 2. To resume scanning, press HOLD/RESUME. Note: Highway Warning Alert does not work while in the HOLD mode. Highway Warning Alert The scanner alerts you when Highway Patrol/State Police units using mobile extenders are within an approximate three mile radius. 1. The ALERT Light flashes and the Alert Tone beeps twice when a signal is received. 2. The ALERT Light glows st eadily for approximately three minutes. Then, if no other mob ile extender transmissions are received, the light goes out. 3. If more transmissions are received before three minutes have passed, the ALERT Light flashes and the Alert Tone beeps once. Alert Tone Volume Push VOL to select Loud, Medium, or Soft. The Alert Tone beeps and the ALERT Light flashes to your choice. Muting the Alert Tone Temporary Mute Press MUTE during the Highway Warning Alert. The Alert Tone stops and the MUTE LED flashes until the alarm cycle (three minutes) is finished. Continuous Mute Press and hold MUTE for two seconds to turn Cont inuous Mute on whenever you wish. You hear two beeps and the MUTE LED lights c ontinuously. No Alert Tones will beep. Canceling Mute To cancel Mute, SQ VOL push

You hear two beeps and the MUTE LED goes out. • Change states. The MUTE LED goes out after scanning starts. • Turn the scanner off and on. Note : If MUTE is pressed for less than 2 seconds during the Continuous Mute mode, nothing will be changed. Alert Light Adjustment The ALERT Light has three settings: Bright, Dim, and Off. Push FLASH to select Bright, Dim or Off. The ALERT Light flashes and the Alert Tone beeps. If you select Off, “ ” on the display reminds you the ALERT Light is off. WARNING : You can turn off the ALERT Light and completely mute the Alert Tone at the same time. This deactivates the Hi ghway Warning Alert. Skip Frequencies To skip a frequency, press L/O. You can program up to 50 skip frequencies for priority channels. And als\ o you can program up to 100 skip frequencies for other frequencies (See page 27). If you\ skip a preprogrammed frequency in one state and that frequency is programmed into another state,
the frequency is skipped of both states. If you change the state code, skipped frequencies are cancelled as soon as scanning starts. Priority Channels Each state preprogrammed in the scanner contains a number of Priority channels. The scanner automatically checks a state’s Prio rity channels every two seconds for activity. If there is activity on one of the Priority channels, the ALERT Light will flash and the alarm tone will beep (see “Highway Warning Alert,” page 17). 18 SQL push FLASH MUTE ALERT Push In Page 18 19 You will experience a slight in the conversations you hear as the scanner checks the Priority channels. You can c ancel the priority check and the interruptions in the conversations by pressing HOLD/RESUME to hold on the frequency. Note: The Highway Warning Alert is inoperative while the scanner is on Hold. Remember to press HOLD/RESUME to return to normal priority-scan operation. Priority channel cannot be changed, but y ou can lock-out priority channels using L/O. Priority channels have been pre-determined by the manufacturer as those Highway Patrol frequencies most commonly used for mob ile extenders and for car-to-car and aircraft-to-car operations. Mobile extenders re-transmit every radio broadcast received on the patrol car radio to the officer’s walkie-talkie at low- power. Every time any officer or dispatcher talks (transmits), the signal is broadcast like a beacon at low-power whether or not the officer is out of the car. You can select Priority Scanning mode by pressing PRI. • Normal Priority Scan mode. The scanner checks the Priority frequency every two seconds. “PRI ” will be displayed. • Priority only mode. To only monitor the priority frequencies, press and hold PRI to select Priority Only. This
mode is especially recommended for the following states: (Arizona) (Michigan) (Delaware) (Oklahoma) (Florida) (Wisconsin) “PRI ” flashes when you select Priority Only Mode. • Priority off mode The scanner does not check the Priority frequency. “PRI” will not displayed. 20-426 8/22/03 1:40 PM Page 19 Trunked Highway Frequency Trunked Highway frequencies ar e pre-programmed for each state. When the scanner finds the control channel data, the scanner begins to find any active IDs. If the scanner finds any ID, the active ID appears on the display and you will hear it. If you press the key while monitoring an ID, the scanner will check to see if any other IDs are active. If none are active, scanning resumes. When the scanner finds a control channel, it wil l stay on that control channel until reception of the control channel is lost. To force t he scanner off of the trucking control channel, press DATA. If you press the key while a talk group ID is active, the frequency on which talk group is transmitting flashes on the display. Or press and hold the key for two seconds, and the ID and the frequency alternately appears on the display. To return to the normal display, press the key again. Like conventional scanning, you can lo ckout reception of unwanted traffic. You can lockout up to 30 IDs. Press L/O on the ID you want to lockout. If you lockout 31st ID, the 1st ID already locked out is restored. If you want to restore all t he locked out IDs, pres and hold L/O for two seconds. Or, when the state code is changed, all lockout IDs are restored as soon as scanning starts. If you find an interesting ID you want to continue listening to, press HOLD/RESUME. Press HOLD/RESUME to resume scanning. You can set the scanner to hold on an ID for two seconds to wait for a replay before scanning resumes. While trunking, press DELAY. “DLY” appears on the display. 20 Page 20 21 Private Bank Scanning Programming Frequencies into Channels
Before the scanner begins Private Bank scanning, you must program a frequency into at least one channel. Program frequencies you purchased from your dealer, from various free and FCC-based sources on the internet, or from the Frequency guide included in 20-426 package. You will need to progr am each frequency into the scanner’s channels in order to hear these frequencies. 1. While Private Bank scanning is activated, press HOLD/RESUME and enter the channel number where you want to store a frequency by using the keypad, then press HOLD/RESUME. ✎ Change the channel by using the or key. 2. Enter the frequency you want to store by using the keypad and (decimal key). 3. Press E to store the frequency into the channel. 4. If you want to program another frequencies into the channel, select another channel by using the or key. Note : • To clear a mistake while enteri ng the frequency, press (decimal key) repeatedly until the display is cleared. • If you enter a invalid frequency, an error tone will sound and appears on the display. To clear the Error message immediately, press (decimal key). • Even if you dont enter full numbers as a frequency number, the scanner will automatically select the nearest valid frequency. Deleting a Stored Frequency To delete a stored frequency: a. Select a channel. b. Press 0. c. Then press E. Note : Channels with no frequencies are automatically locked out. . . . 20-426 8/22/03 1:40 PM Page 21 22 Duplicate Frequency Alert If you enter a frequency which has been stored in another channel, you will hear an error tone and the other channel displays. Press (decimal key) to clear and start again. ––– OR ––– Press E again to store the frequency in both channels.
