、电源管理
7. Power Management
A. 采用 2 节 5 号干电池供电
A. The Product is powered by 2 AA batteries
B. 低电检测和提示
B. Low-battery detection and prompt
a. VBAT<=2.2V 开始提示低电，VBAT <= 2V 以下禁止工作，重上电才能恢复
a. The Product prompts “low battery” if VBAT<=2.2V, or disables operation if VBAT <= 2V unless it is repowered
b. 检测到禁止工作电压，红灯快速闪烁 10 秒后进入禁止，这 10 秒内可以正常工作，同时间隔 3 秒发送一次禁
止工作键值，可发 F20。
b. Upon detecting voltage of prohibiting work, the Product’s red indicator will flicker for 10s quickly before entering
disabling mode, but the Product can be handled normally 10s before disabling. Meanwhile, the key value of disabling
work will be sent at interval of 3s and it can send the value F20.

、固定频点发送（测发射功率及频偏）：
8. Fixed-frequency Transmission (measure transmitting power and frequency offset):
进入条件
Entry
condition
1：按住“返回键”，遥控器上电，仅检测到“返回键”键被按下，且保持仅“返回键”按下达到 1
秒，遥控器进入固定频点发送。指示灯 100ms 快速闪烁
1: Hold “Return” key and power on the Product, if “Return” key is pressed and held for 1s, the
Product will enable transmission at fixed frequency. The indicator will flicker quickly at interval of
100 ms.
2：也可整机测试工具配置
2: Tool configuration can be tested
3：注意点
3: Notice
1）非按住“返回键”上电的不可进入，通过初始化完是否检测到“返回键”判断
1) The fixed-frequency transmission mode cannot be entered unless “Return” key is pressed
before powering on; the “Return” key is detected through initialization.
2）上电 1 秒内只能有“返回键”是按下状态，且要维持 1 秒才进入
2) The fixed-frequency transmission mode cannot be entered unless “Return” key is pressed
before powering on for 1s;
3）休眠情况下唤醒不算重新上电，需要注意
3) Please be noted, awakening from sleep mode is not regarded as repowering
