K97SDW-150Wireless Digital Microphone

Operation of SDW-150 The Wireless Digital Microphone A. System link: For your first use of SDW-150, turn the power of transmitter and receiver on, and press the “LINK” button on the transmitter. The “STATE” LED of both the transmitter and receiver will light up and start to flash three times (time interval at 1.3 sec.) and change to light still when the system links successfully. This process shall be done if the SDW-150 has not been used for a period of days. For your next use of SDW-150, the system will link automatically when you turn on the transmitter and receiver, and the LED of each unit will light still. If the receiver is out of range, the LED will flash quickly and stop signal receipt, you need to bring the receiver closer to the transmitter, and push the LINK button again until the LED turns light still. B. Battery low The LED of each unit will flash frequently (time interval at 0.3 sec.) when the power is at low level, please change new batteries for the unit. The transmitting range will be reduced when the battery power is not supplied enough.
