目 录
感谢您购买本产品，请在使用前仔细阅读说明
书，并保留以备将来查验。
预防措施
•
只能在24V直流供电负极接地的系统中使
用。
• 安装和连接时，要切断汽车电池的负端。
•
更换保险丝时，要确保使用相同规格的保险
丝。如果使用规格不同的保险丝，会对机器
产生严重损害。
•
要确保尖针或其它外部物体不会进入机器内
部，否则将会引起故障，或者危及设备安
全。例如：电击。
•
如果你的汽车在过冷或过热的环境中放置一
段较长的时间，那么可能要等到车内的温度
恢复正常时才能操作。
•
把音量调节到能听到外部警报声的位置(例
如：喇叭声等)。
操作前
•
不要把音量调得太大，因为声音过大会妨碍
外界声音，以致发生交通事故。
• 在进行较复杂操作时，要先将车停靠。
注意事项
•
不要擅自打开外壳进行修理，请咨询您的经
销商或是有经验的技术人员。

PRECAUTIONS
• Use only in a 24-volt DC negative-ground
electrical system.
• Disconnect the vehicle's negative battery
terminal while mounting and connecting
the unit.
• When replacing the fuse, be sure to use
one with an identical amperage rating.
Using a fuse with a higher amperage
rating may cause serious damage to the
unit.
• Make sure that pins or other foreign
objects do not get inside the unit, they
may cause malfunctions, or create safety
hazards such as electrical shock.
• If you have parked the car for a long
time in hot or cold weather, wait until the
temperature in the car becomes normal
before operating the unit.
• Keep the volume at a level at which you
can hear outside warning sounds (horns
sirens, etc.).
CAUTION
• DO NOT open covers and do not repair
yourself. Consult the dealer or an
experienced technician for help.
BEFORE OPERATION
• Do not raise the volume level too much,
as this will block outside sounds, making
driving dangerous.
• Stop the car before performing any
complicated operation.
