Initializing

If no sound is heard from one side of the earphones or the earphones cannot be connected to your BLUETOOTH device, initializing the earphones may solve the problem.

Information of all the paired devices will be deleted (initialized). Perform pairing again from the start.

Start by deleting the registration information of the System from the BLUETOOTH setting on the BLUETOOTH device.

Charge the charging case beforehand.

Remove the earphones once if they are inserted into the charging case.

There are two initialization procedures. Refer to the procedure below.

Check the serial number on the bottom of the charging case and that it is underlined.

Serial_EC25T + Serial_EC25T

Bottom of the charging case

Serial number

Underline

If the serial number is not underlined, follow the Procedure A (Procedure A) to initialize.

If the serial number is underlined, follow the Procedure B (Procedure B) to initialize.

If you can’t tell if the serial number is underlined or not, initialize by following the Procedure A. Continue with the Procedure B if initialization fails.

Follow the steps below to initialize the settings of both L and R earphones.

Initialize the L earphone.

1Insert the L earphone into the charging case.

2When the indicator for L earphone is lighting up, press and hold the L touch sensor area for about 15 seconds.

Initializing_L_2_EC25T + SPNV_initializing_EC25T_L_2

Touch sensor area

Release your finger after the L indicator flashes twice.

After the indicator has flashed, the L side is initialized. The L earphone switches to the charging state and the L indicator lights up.

If the indicator does not flash, start over from step 1.

Initialize the R earphone.

3Insert the R earphone into the charging case.

Touch sensor area

Release your finger after the R indicator flashes twice.

After the indicator has flashed, the R side is initialized. The R earphone switches to the charging state and the R indicator lights up.

If the indicator does not flash, start over from step 3.

5Remove the earphones from the charging case and set the L and R earphones side by side.

The L and R indicators light up and the power turns on.

6After a short while, the L indicator starts to flash quickly and repeatedly. The R indicator flashes twice every 5 seconds repeatedly.

connecting_LR_2_EC25T

Initialization is now complete.

Information of all paired devices has been deleted. Pair the respective Bluetooth devices (device registration) again. Pairing for the First Time

If initialization fails, the R indicator won't flash twice every 5 seconds. In such case, start the initialization procedure again from the beginning.

When the sound only emits from one side of the earphones even when the earphones are connected to the BLUETOOTH device, touch and hold the touch sensor area on both earphones again to turn off the power and repeat the steps from the beginning.

Follow the steps below to initialize the settings of both L and R earphones.

Initialize the L earphone.

1Insert the L earphone into the charging case.

The indicator will stop flashing after 5 seconds. Tap it twice quickly while it is still flashing.

After initialization is complete, the L indicator will flash twice slowly.

If initialization is not successful, start over from step 1.

Connect the L earphone with the R earphone.

7Take out both the L and R earphones and place them side by side.

Be careful not to touch the touch sensor area when taking them out.
