RF15B04 has two working modes: Normal Mode and Low-Power Mode.
How to switch modes:
In Normal Mode, press and hold the button to power on to enter Low-Power Mode;
In Low-Power Mode, press and hold the button to power on to Normal Mode.
Normal mode: The average standby current is 6mA, the LED light (PWR) will be always on, and when a valid remote control (EV1527/PT2262) key value is received, the LED will flash rapidly.
Low-Power Mode: The average standby current is 135uA, and the LED light (PWR) will be off. Usually, when RF15B04 is in Sleep State,you need to keep pressing the button for 4 seconds to activate RF15B04. After activation, RF15B04 can be controlled normally. No pressing again for 30 seconds Press the button, RF15B04 will resume the Sleep State.
Note: Low-Power Mode, you need to keep pressing any button for 4 seconds (or pressing the button multiple times) to activate the RF15B04.
Description of Average Standby Current in Low Power Mode:
Working current: Normal Mode working current: 6mA
Sleep current: Current in sleep state in Low Power Mode: 3uA
Average standby current in Low Power Mode: RF15B044000MS sleep in Low Power Mode, 90MS wake-up scan. That is, the current of RF15B04 entering 400:9 sleep and wake-up scan state: 135uA (6MA/44).
Current test description: The average standby current is calculated according to the sleep and wake-up ratio and the working current. It is difficult to measure this average standby current with a multimeter. At the same time, the meter line of the multimeter will interfere with the receiving chip being continuously awakened to detect and process data, resulting in fluctuations in the current.
