Slide the USB DIRECT slide lever on the back of the IC recorder in the direction of the arrow, so that the USB connector appears. Then, insert the USB connector into the USB port of a running computer. (*1)

While the battery is charging, “Connecting” and the battery indicator () are displayed in an animation.

When the battery is fully charged, the battery indicator will indicate “” ().

When you charge the IC recorder for the first time, or when you have not used the IC recorder for a long time, charge the rechargeable battery until the “” indicator appears on the display. It takes about 4 hours to fully charge an exhausted battery. (*2)

^*1 If the IC recorder cannot be connected to a computer directly, use the supplied USB connection support cable.

^*2 This is an approximation for the time it takes to charge from no remaining battery power to full battery power at room temperature. It varies depending on the remaining power and the condition of the battery. It also takes more time if the temperature of the battery is low, or if the battery is charged while you are transferring data to the IC recorder.
