检测到强磁场

提醒检测到强磁场但是找不到为什么，期望增加一个磁场范围检测

Response from developer

感谢反馈！目前只能判断磁场是否偏高，无法定位具体干扰源，该提示仅供环境参考，不影响正常对时。 对时成功的关键点是：选择正确电波台、手表进入 RC/RCV 接收模式、iPhone 音量调到最大，并让手表尽量贴近手机扬声器或最佳接收位置。

还不错，继续努力

手动调时间看不懂，希望简单一点

Response from developer

感谢您的反馈和支持！ 这里的“手动调时间”是指先在手表上启动“手动收波/手动接收”，再由 App 发出校时信号，并不是直接在 App 内修改手表时间。 您可以进入“使用指南”，选择对应的手表品牌，按照页面上的步骤操作。不同品牌和型号的按键方式可能不同；如果没有对应型号，请以手表说明书中的“手动收波”步骤为准。我们会继续简化操作说明，让流程更容易理解。
