FOR 2 USERS
- Disconnect the microphone of the other set
- If the noise stops, replace with new microphone
- If crackling noise goes away and you are able to communicate clearly, this is due to a damaged microphone.
- If noise is still present, check the connector for signs of dampness and also for dielectric grease.
- Wash connector of the set with fresh water and shake or use compressed air if you have to remove water. Let it dry completely in the hot sun or blow with hair dryer taking care not to melt the plastic. Do not try to use paper to push inside the connector as it may damage it the pin.
- Fill the connector with dielectric grease as much as you can and remove excess grease after connecting the microphone. If this still does not work, the set is faulty and needs to be repaired or replace. If it is still under warranty, contact your dealer for replacement.

IT IS IMPORTANT TO ENSURE CONNECTORS ARE FILLED WITH DIELECTRIC GREASE WHENEVER THE SPEAKER OR MICROPHONE IS REPLACED. REPLACEMENT PARTS ALWAYS COME PRE-FILLED WITH DIELECTRIC GREASE.
FOR CHARGING CONNECTOR, DO ENSURE YOU HAVE DIELECTRIC GREASE TO APPLY AS AND WHEN NEEDED SHOULD THEY BECOME THIN BY VISUAL CHECK AFTER UNPLUGGING TO CHARGE SEVERAL TIMES. THIS CAN BE ANY WHERE BETWEEN 3-5 TIMES.
