              Basic inspection

              Procedure                        Inspection content                            Measure

                        Check the battery voltage                             Yes    Go to Step 2
                  1     ● Battery voltage shall not be lower than 21V
                                                                               No    Charging or replacing battery
                        Check if the result is ok?

                        Check the fuse                                        Yes    Replace the same spec fuse
                  2     ● Check if the fuse is broken
                                                                               No    Go to Step 3
                        Check if the result is ok?

                        Check the antenna                                     Yes    Go to Step 4
                        ● If the antenna is pulled out to the longest position.
                  3     ● Are there any foreign objects covering the antenna?
                                                                               No    Repair or replace the antenna
                        ● If the antenna is bent or deformed.
                        Check if the result is ok?

                        Radio wave check                                             Go to the failure
                                                                              Yes
                        ● The coverage areas of AM and FM broadcast are different widely,   phenomenon list
                        AM broadcasts can be sometimes clearly received, and FM stereo is
                        not  available.  The  FM  stereo  covers  the  smallest  area  and  is
                        susceptible to electromagnetic interference.
                  4     ●  Check  whether there are  tall  buildings  or  mountains around the
                                                                                     Move the vehicle to the
                        vehicle, which may block some signals from the launch tower to the
                                                                               No
                                                                                     palce with good signal
                        vehicle.
                        ● Some buildings reflect broadcast signals due to building materials,
                        causing that two signals are received and interfered.

                        Check if the result is ok?
