4.3 Installing Batteries in Microphones
Each handheld microphone requires two AA batteries. Ensure correct polarity when inserting the batteries.
- Unscrew the bottom cap of the microphone to reveal the battery compartment.
- Вставьте две батарейки типа АА, соблюдая полярность (+/-).
- Плотно закрутите нижнюю крышку обратно.

5. Инструкция по эксплуатации
5.1 Включение/выключение питания
- Получатель: Press the POWER button on the front panel of the receiver to turn it on or off.
- Микрофоны: Press and hold the power button on each handheld microphone for a few seconds to turn it on or off. The OLED screen will illuminate when powered on.
5.2 Frequency Synchronization (IR Sync)
The WM-419 features Intelligent Frequency Autoscan and IR Synchronization for easy setup.
- Turn on the receiver and the desired microphone.
- На приемнике нажмите СКАНИРОВАНИЕ button for the channel you wish to set. The receiver will automatically scan for an available clear frequency.
- Once a frequency is found, the display will show "SYNC". Position the IR window of the microphone (usually near the bottom of the display) close to the IR sensor on the receiver (located near the channel display).
- Нажмите НАБОР button on the receiver for that channel. The frequency information will be transmitted to the microphone via infrared. The microphone's display should show the same frequency as the receiver, indicating successful synchronization.
- Repeat this process for each microphone.
