4.1 Description
LBB 4540 receivers are available for 4, 8 or 32 chan-
nels. They can operate with a rechargeable NiMH bat-
tery pack or with disposable batteries and have con-
trols for channel selection, volume adjustment and an
on/off push button. All receivers have a 3.5 mm (0.14
inch) stereo jack output socket for mono or stereo
headphones.
An LCD display shows the channel number and indi-
cators for signal reception and low battery power.
Charging circuitry is included in the receiver.
