Should the charging light of the RS 120 always remain on?

On the front of the transmitter there is the battery charging indicator light and when the battery is charging this indicator will light up RED. Any time the battery is charging (ie: the headphones are on the charging cradle) this light will be lit RED and it will NOT turn off until the headphones are removed from the charger.

NOTE: The batteries cannot be overcharged because Sennheiser utilizes "trickle charge" technology so that once a battery is charged the charging switches to a lower level to maintain the battery's full charge.
