If, once charging is complete, the battery in the microphone spontaneously drains, charging will not start again even if the microphone is still inserted into the charger.
If the [CHG] indicator does not light up despite the microphone being inserted into the charger, confirm that all the links between charger, AC adapter, power cable, and electric plug are securely connected.
The charging time depends on the battery type and the specific use situation, but at longest it will be around eight hours.
Charging the batteries outside of their operating temperature range may substantially increase the amount of time required for charging. Even if the batteries are within their operating temperature range, charging while the microphone is very hot or cold may increase the amount of time required for charging.
Both the microphone and the charger normally become hot during charging. This is not due to a malfunction.
Do not try to charge already full batteries. Doing so will reduce the lifespan of the batteries.
Some kinds of batteries may not be fully recharged in just one cycle and the runtime becomes small. This happens to the batteries which are being used for the first time, batteries which have not been used for a long (more than three months) time, and batteries which have been recharged and depleted numerous times. This phenomenon is characteristic of the rechargeable batteries. The battery runtime may be recovered to the normal level by completely charging and then depleting (by using the microphone) the batteries two or three times.
The charger automatically recognizes the dry-cell battery inside the microphone to cancels charging, and then the [CHG] indicator will blink. However, depending on the type of dry-cell battery, this automatic recognition may take some time and the [CHG] indicator stay lit until the recognition completes.
Sometimes, when trying to recharge almost-full batteries at very low temperatures, these may be mistakenly recognized as dry-cell batteries, and the [CHG] indicator may start blinking.
The microphone is charged through inductive charging. Because of inductive charging regulations, the [PWR] indicator on the microphone may go off multiple times just before charging is completed, but this does not indicate a malfunction.
Sometimes, when trying to charge almost-empty batteries, these may be mistakenly recognized as dry-cell batteries, stopping the charging and making the [CHG] indicator start blinking. If this happens, remove the microphone from the charger and re-insert it multiple times until the batteries are properly recognized. If the batteries cannot be recharged despite multiple attempts, it means that they are completely exhausted and need to be replaced.

The product does not turn ON| Have you inserted the dry-cell battery or the rechargeable battery?

¨ Make sure that the battery is inserted.

| 16
Is the microphone currently inserted into the charger?

¨ Even if the [CHG] indicator does not light up, the microphone cannot be turned ON as long as it is inserted into the charger.

Take the microphone out of the charger and then turn it ON.

| 32
Is the battery depleted?

¨ If it is, replace it (if it is the dry-cell battery) or charge it (if it is the rechargeable battery).

| 30, 32
Is the battery inserted according to the correct polarities? (Positive , negative )

¨ Make sure that the battery is inserted correctly.

| 16, 30
The [PWR] indicator blinks red and I cannot use the microphone| The microphone is not paired. Alternatively, there could have been an error during the pairing process due to a bad connection.

¨ Place the microphone as close as possible to the antenna and try pairing it again.

| 20
The [PWR] indicator blinks orange and I cannot use the microphone| The microphone may be outside of the antenna range, and it cannot establish a connection.

¨ Move the microphone inside the antenna range.

---|---|---
The [PWR] indicator blinks green and I cannot use the microphone| You cannot use the microphone because there is another active microphone paired to the same channel.

¨ Stop using the other microphone paired to the same channel.

| 13
The microphone may be almost outside of the antenna range.

¨ Move the microphone inside the antenna range.

| 13
Audio from the microphone unit is not transmitted| Is an external device connected to the [AUDIOIN] connector?

¨ When an external device is connected, even if it is turned OFF, it will take precedence over the microphone unit, which will stop audio transmission from the microphone unit. Disconnect the plug from the [AUDIO IN] connector.

| 29
Is the volume on the receiver, connected amplifier, etc. high enough?

¨ Adjust the volume with the volume adjustment knob.

| ―
I cannot charge the microphone

(The [CHG] indicator stays off)

| Is the microphone properly inserted into the charger?

¨ Make sure that the microphone is properly inserted into the charger.

| 32
I cannot charge the microphone

(The [CHG] indicator only stays on for a few minutes)

| Is the battery already charged?

¨ The battery may already be fully charged. Take the microphone out of the charger and use it as normal.
