I followed the steps in section 5.2 of the GREEN KEEPER GKD60 manual, but the wireless microphones are not connecting. How can I fix this?

If the wireless microphones for your GREEN KEEPER GKD60 are not connecting after following the standard setup in section 5.2, please try the following troubleshooting steps:Check Battery Orientation: Ensure the batteries in the microphones are inserted correctly according to the polarity (+/-) markings. Even if they are new, a single reversed battery will prevent the microphone from powering on or pairing.Verify Power Status: Confirm that the microphone's display or indicator light turns on when you power it up. If there is no light, replace the batteries with fresh ones.Proximity: Ensure the microphones are within close range (1-3 meters) of the speaker during the initial pairing process.Check Speaker Mode: While the microphones should pair automatically in most modes, ensure the speaker is fully powered on and not in a standby state.Interference: Move the speaker away from other high-powered wireless devices (like Wi-Fi routers or other large Bluetooth systems) that might be interfering with the 2.4GHz or UHF signal used by the microphones.If the microphones still do not connect, the manual suggests contacting the retailer or the GREEN KEEPER customer service department for technical support, as there may be a hardware sync issue that requires a manual reset procedure not detailed in the standard text.
