有关您的扫描仪
一旦你理解了本手册中使用的一些简单的术语，熟悉扫描仪的功能，你可以把扫描仪为你工作。您只需确定你想要的类型的通信接收，然后将扫描仪进行扫描。
的频率是接收信号的位置（kHz 或 MHz）。找到活动的频率，你可以使用搜索或调整功能。
当你找到一个频率，你可以把它存储到一个可编程存储器单元称为一个通道，这是与其他信道进行分组一个通道存储银行中。然后，您可以扫描通道存储银行存储在那里的频率是否有活动。每次扫描仪找到一个活动的频率，它停留在该通道，直到发送结束。这种扫描仪具有独立的通道扫描仪模式之间的位置（共 300 个通道）和 FM 收音机模式（共 20 个通道）。
3。装入三节 AA 电池，匹配的极性符号（+， - ）标记内。
4。更换的电池仓盖。设置的 ALK 如果您使用碱性 batteriesSet 如果您使用的镍氢（Ni-MH）充电镍氢（Ni-MH）电池
警告：切勿安装碱性电池，镍氢（Ni-MH）电池类型选择开关设置。碱性电池会变热，或爆炸，如果您尝试充电。
交通安全

FM是指其基本特征是载波的振荡幅度保持不变，振荡频率随调制信号而变，就是高频载波的频率不是一个常数，是随调制信号而在一定范围内变化的调制方式，其幅值则是一个常数。

与其对应的，调幅就是载频的频率是不变的，其幅值随调制信号而变。

本设计是通过MATLAB/Simulink对AM和FM进行调制解调，并在不同环境查看AM与FM时域与频域波形，进行比对，并得出仿真结果，分析比较两种种不同的调制方式所存在的不同。

AM FM 收音机功能手册说明书

Radio signals,especially on the FM band,are deflected by large objects such as buildings and hills.Your radio then receives both the direct signal from the station’s transmitter,and the deflected signal.This causes the sound to distort or flutter.This is a main cause of poor radio reception in city driving.As required by the FCC:Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.AM/FM Radio ReceptionFeatures179The auxiliary input jack isunderneath the accessory power socket in the console compartment.The system will accept auxiliary input from standard audioaccessories using a 1/8inch stereo miniplug.When a compatible audio unit isconnected to the jack,press the AUX button to select it.Auxiliary Input Jack180The VOL button adjusts the volume up ()or down ().Press the top or bottom of the button,hold it until the desired volume is reached,then release it.If you are listening to the radio,use the CH button to change stations.Each time you press the top ()of the button,the system goes to the next preset station on the band you are listening to.Press the bottom ()to go back to the previous station.Three controls for the audio system are mounted in the steering wheel hub.These let you control basic functions without removing your hand from the wheel.The MODE button changes the mode.Pressing the buttonrepeatedly selects FM1,FM2,AM,XM Radio (U.S.models),a disc (if a disc is loaded),or a tape (if a tape is loaded).To activate the seek function,press and hold the top ()or bottom ()of the CH button until you hear a beep.The system searches up or down from the current frequency to find a station with a strong signal.If you are playing a disc,the system skips to the beginning of the next track (file in MP3or WMA format)each time you press the top ()of the CH button.Press the bottom ()to return to the beginning of the current track or file.Press it twice to return to the previous track or file.You will see the track/file number and the elapsed time.If the disc has text data or is compressed in MP3or WMA,you can also see any other information (track title,file name,folder name,etc.).CONTINUEDRemote Audio ControlsFeatures181If you make a mistake entering the code,do not start over;complete the five-digit sequence,then enter the correct code.You have 10tries to enter the correct code.If you are unsuccessful in 10attempts,you must then leave the system on for 1hour before trying again.Your vehicle’s audio system will disable itself if it is disconnected from electrical power for any reason.To make it work again,you must enter a specific five-digit code in the preset buttons.Because there are hundreds of number combinations possible from five digits,making the system work without knowing the exact code is nearly impossible.You should have received a card that lists your audio system code number and serial number.It is best to store this card in a safe place at home.In addition,you should write the audio system’s serial number in this owner’s manual.If you should happen to lose the card,you must obtain the code number from your dealer.To do this,you will need the system’s serial number.If your vehicle’s battery is discon-nected or goes dead,the audio system will disable itself.If thishappens,you will see ‘‘CODE’’in the frequency display the next time you turn on the e the preset buttons to enter the five-digit code.The code is on the radio code card included in your owner’s manual kit.When it is entered correctly,the radio will start playing.If the code card is lost,your dealer can access your code with yourradio’s serial number.To access the serial number,turn the radio on.It must display ‘‘CODE’’,then turn theradio off.Push the preset 1,preset 6,and power buttons at the same time,then quickly release.The serial number will appear.Radio Theft Protection182The security system automatically sets 15 seconds after you lock the doors, hood, and trunk. For the system to activate, you must lock the doors from the outside with the key, lock tab, door lock switch, or remote transmitter. The security system indicator next to the driver’s door lock starts blinking immediately to show you the system is setting itself.With the system set, you can still open the trunk with the remote transmitter without triggering the alarm. The alarm will sound if the trunk is opened with the trunk release button on the driver’s door, the trunk release handle behind the trunk pass-through cover, or the emergency trunk opener.Do not attempt to alter this system or add other devices to it.The security system helps to protect your vehicle and valuables from theft. The horn sounds and a combination of headlights, parking lights, side marker lights and taillights flash if someone attempts to break into your vehicle or remove the radio.This alarm continues for 2 minutes, then the system resets. To reset analarming system before the 2 minutes have elapsed, unlock the driver’s door with the key or use the remote transmitter.The security system will not set ifthe hood,trunk,or any door is notfully closed.If the system will not set, check the door and trunk openmonitor on the multi-information display(see page)to see if thedoors and trunk are fully closed.Since it is not part of the monitor display,manually check the hood.68Security SystemFeatures183Cruise control allows you to maintain a set speed above 25mph (40km/h)without keeping your foot on the accelerator pedal.It should be used for cruising on straight,openhighways.It is not recommended for city driving,winding roads,slippery roads,heavy rain,or bad weather.When climbing a steep hill,the automatic transmission may downshift to hold the set speed.Press and release the SET/DECEL button on the steering wheel.The CRUISE CONTROL indicator on the instrument panel comes on to show the system is now activated.Cruise control may not hold the set speed when you are going up and down hills.If your vehicle speed increases going down a hill,use the brakes to slow down.This will cancel the cruise control.To resume the set speed,press the RES/ACCEL button.The CRUISE CONTROL indicator on the instrument panel will come back on.3.Cruise Control184You can increase the set cruising speed in any of these ways:Press and hold the RES/ACCEL button.When you reach thedesired cruising speed,release the button.To increase the speed in very small amounts,tap the RES/ACCEL button.Each time you do this,your vehicle speeds up about 1mph (1.6km/h).Resting your foot on the brake or clutch pedal causes cruise control to cancel.Push on the accelerator pedal.Accelerate to the desired cruising speed,then press the SET/DECEL button.Even with cruise control on,you can still use the accelerator pedal to speed up for passing.Aftercompleting the pass,take your foot off the accelerator pedal.The vehicle will return to the set cruising speed.Changing the Set SpeedCruise ControlFeatures185Tap the brake or clutch pedal.Push the CANCEL button on the steering wheel.You can cancel cruise control in any of these ways:Push the CRUISE button on the steering wheel.Pressing the CRUISE button turns the system completely off and erases the previous cruising speed.When you push the CANCEL button,or tap the brake or clutch pedal,the system remembers the previously set cruising speed.To return to that speed,accelerate to above 25mph (40km/h)and then press andrelease the RES/ACCEL button.The CRUISE CONTROL indicator comes on,and the vehicle accelerates to the same cruising speed as before.Resuming the Set SpeedCancelling Cruise ControlCruise Control186If you are training HomeLink to operate a garage door or gate,you should unplug the motor for that device during training.Repeatedly pressing the remote control button could burn out the motor.HomeLink stores the code in a permanent memory.There should be no need to retrain HomeLink if your vehicle’s battery goes dead or is disconnected.If your garage door opener wasmanufactured before April 1982,you may not be able to programHomeLink to operate it.They do not have the safety feature that causesthe motor to stop and reverse if an obstacle is detected during closing,increasing the risk of injury.The HomeLink UniversalTransceiver built into your vehicle can be programmed to operate up to three remote controlled devices around your home,such as garage doors,lighting,or home security systems.Always refer to the openinginstructions and safety information that came with your garage door opener or other equipment youintend to operate with HomeLink.If you do not have this information,contact the manufacturer of the equipment.If you justreceived your vehicle and have not trained any of the buttons inHomeLink before,you should erase any previously learned codes before training the first button.If you are training the second or third buttons,go directly to step 1.For quick and accurate training,make sure the remote transmitter for the device (garage door,automatic gate,security system,etc.)has a fresh battery.To do this,press and hold the two outside buttons on the HomeLink transceiver for about 10seconds,until the red indicator flashes.Release the buttons,then proceed to step 1in the chart on the next page.Before you begin CONTINUEDGeneral InformationImportant Safety Precautions Training HomeLinkHomeLink Universal TransceiverFeatures187。

FM AM 广播频率介绍

FM、AM介绍FM、AM是根据频率对广播的一种分类方式。

一般来说AM频率的电台是相对于远距离传播的节目用的，其福射范围大，是长波，多为一些大电台彩的方式，比如说美车之音啊，中央的一些节目啊，但是其收听效果不好，音质差，我们称为调幅广播。

FM则与之相反，其福射范围小，多在几十公里之内，比如一些城里的，学校里的电台之类，其针对性较强，我们平时听的广播节目多为这类，称为调频广播，音质较好。

【AM/FM介绍】什么是调幅波？什么是调频波？使载波振幅按照调制信号改变的调制方式叫调幅AM。

经过调幅的电波叫调幅波。

它保持着高频载波的频率特性，但包络线的形状则和信号波形相似。

调幅波的振幅大小，由调制信号的强度决定。

调幅波用英文字母AM 表示。

使载波频率按照调制信号改变的调制方式叫调频FM。

已调波频率变化的大小由调制信号的大小决定，变化的周期由调制信号的频率决定。

已调波的振幅保持不变。

调频波的波形，就像是个被压缩得不均匀的弹簧，调频波用英文字母FM表示。

目前，调幅制无线电广播分做长波、中波和短波三个大波段，分别由相应波段的无线电波传送信号。

我国只有中波和短波两个大波段的无线电广播。

中波广播使用的频段大致为550kHz-1600kHz，主要靠地波传播，也伴有部分天波；短波广播使用的频段约为2MHz-24MHz，主要靠天波传播，近距离内伴有地波。

调频制无线电广播多用超短波(甚高频)无线电波传送信号，使用频率约为88MHz-108MHz，主要靠空间波传送信号。

目前，地面的广播电视分做VHF(甚高频或称米波)和UHF(特高频或称分米波)两个频段。

在我国，VHF频段电视使用的频率范围是48.5MHz-3MHz，划分成1-12频道，UHF频段使用的频率范围是470MHz-956MHz，划分成：3-68频道。

它们基本上都是靠空间波传播的。

国际上规定的卫星广播电视有6个频段，主要频段是12kMHz，也是靠空间波传播。

广播节目的发送是在广播电台进行。
