The sleek but robust SL Handheld DW is optimized for

speech in presentations or lectures where every word

matters. Thanks to bi-directional communication be-

tween transmitter and receiver, no settings need to be

adjusted on the transmitter. The automatic frequency and

interference management allows convenient and reliable

operation. The LC display provides the link name, battery

status and reception quality. The ergonomically positioned

mute-slider makes the use of the microphone very con-

venient. The SL Handheld DW comes with a rechargeable

Li-Ion battery with external charging contacts - for easy

charging with the CHG 2 - and a USB socket.
