Charging the battery
Place the receiver into the transmitter’s
charging compartment, with the operating
control at the front. Pull the 3.5 mm stereo
plug out of the receiver to turn the receiver
off. The left LED on the transmitter must li-
ght up.
Charge the battery for 24 hours before
you use it for the first time. The normal
charging time is 4-5 hours. A fully char-
ged battery has an operating time of approx. 4 hours. When charging a
spare battery in the small charging compartment at the right of the trans-
mitter, charging time is 10-12 hours.
The transmitter automatically switches to trickle charging so that the
battery cannot be overcharged. The receiver can remain in the charging
compartment even when the battery has been fully charged.
