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.

Possibly the problem reveals to be an operational error.3PROTECTIVE CIRCUITSYour new Warwick amplifier is equipped with a series of circuits to prevent it from destruction in case of inadequate ope-rating conditions:Power-up delay:When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay toprotect the loudspeakers.Short-circuit:In the event of a short-circuit at the power amp outputs, this feature prevents the output stagetransistors from destruction by quickly reducing current.Direct current (DC):This circuit continuously monitors the power amp output for direct current and protects the loud speakers from overload should a transistor burn out.HF oscillation:By switching the power amp off, this safety feature prevents from damages that could be caused by frequencies in excess of 20 kHz (feedback, etc.).Excessivetemperatures:Should the temperature-regulated fan cooler prove to be insufficient in extreme conditions, this circuit protects the output stage transistors from destruction by switching the device off.Limiter:The combos CL and CCL are equipped with a limiter, that limits the poweramp outputs to200 watts (CL), 300 watts (CCL) in order to protect the loudspeakers.Note:You can recognise that one of these circuits has been activated as a result of a fault, when theMUTE LED glows continuously even though you have not selected the MUTE mode. In case ofa short-circuit please check the speaker cable. The amplifier must then be switched off and onagain, to get back into playing mode after having removed the short-circuit. In any other situationthe amplifier switches automatically back to playing mode as soon as it detects the fault hasdisappeared (e.g. the amplifier has overheated and cooled down again).GETTING STARTED1.Make sure that loudspeakers capable of sustaining the load of a bass signal are connected to the SPEAKER OUTsockets, resp. the speaker unit should be linked to the SPEAKER OUT at the combos.2.Check that the mains supply has been plugged in and that all external (effects) units possibly used are correctly con-nected and operational.3.Set the MASTER control to zero.4.Plug your bass guitar into the amplifier's INPUT with a shielded line-cable.5. Press the POWER switch to turn the device on.6. Switch MUTE off and the red LED will extinguish.7. Switch the LIMITER off (the 2-colored LED will extinguish, CL, CCL).8.

用万用表测量场效应管极性及好坏判断
1、测量
极性及管型判断
红笔接Ｓ、黑笔接Ｄ值为（300-800）为Ｎ沟道
红笔接Ｄ、黑笔接Ｓ值为（300-800）为ｐ沟道
如果先没Ｇ、Ｄ再没Ｓ、Ｄ会长响，表笔放在Ｇ和最短脚相连放电，如果再长响为击穿
贴片场管与三极管难以区分，先按三极管没，如果不是按场管测
场管测量时，最好取下来测，在主板上测量会不准
2、好坏判断
测Ｄ、Ｓ两脚值为（300-800）为正常，如果显示“０”且长响，场管击穿；如果显示“１”，场管为开路
软击穿(测量是好的，换到主板上是坏的），场管输出不受G极控制。
