Connecting and disconnecting the microphone cable:
1. Insert the XLR connector into the microphone. If necessary, rotate the connector to align with the ridge and the groove in the microphone.
Push the connector into the microphone until it clicks.
2. To disconnect the cable and microphone, grasp the connector while depressing the tab. Pull the connector away from the microphone.
Caution:
1. If the head of the microphone is covered by hand or brought close to a speaker, a howling sound may be generated. To prevent this, first
decrease the volume, and place the microphone so that it is not pointed to the speaker. In addition, make sure that there is sufficient
distance between the microphone and speaker.
2. Due to the high sensitivity of the cartridge, be careful not to drop the microphone and protect it from sudden jolts.
3. To maintain the sensitivity and quality of sound reproduction, avoid exposing it to moisture and extreme temperatures.
