Series LBB 3433 receivers can demodulate up to 7 audio channels. The LBB 3433/10 and LBB 3433/15 uses rechargeable batteries and has a mean operating time of 90 hours. The batteries typically take 1.5 hours to recharge, using a specially designed quick charging unit. The LBB 3433/00 uses disposable batteries (not included) - such as Philips LR6 mercury- and cadmium-free alkaline cells - which give a mean operating time of 350 hours.

Series LBB 3434 receivers, designed for more extensive interpretation systems, can demodulate up to 16 audio channels. A switch inside the battery compartment allows preselection of the maximum number or channels (8, 12, or 16) and selection of the channel shift function. The channel shift function can be easily used in combination with the Infra-red Transmitter, LBB 3420. The LBB 3434/10 uses rechargeable batteries and has a mean operating time of 90 hours. The batteries typically take 1.5 hours to recharge, using a specially designed quick charging unit. The LBB 3434/00 uses disposable batteries (not included) - such as Philips LR6 mercury- and cadmium-free alkaline cells - which give a mean operating time of 350 hours. An LCD display is provided to give at-a-glance information which includes channel number and low battery power indication. It has push button controls for maximum ease of use and a speech boost facility to ensure superior speech intelligibility. An upshift channel selection function enables channels to be used which are not affected by interference from fluorescent lamps operating at 28 kHz.

This suitcase is used to recharge receiver units type LBB 3432/10, LBB 3433/10, LBB 3433/15 and LBB 3434/10. The suitcase design is ideal for convenient storage and transportation of infra-red receivers. Each charging position is linked to a microprocessor for controlling the charging rate according to the pulse charge principle, ensuring optimum charging performance and maximum battery lifetime.This suitcase can be set for quick with auto-trickle charge. Quick-charge is normally used. Auto-trickle charge ensures the batteries are always fully charged. Trickle-charge is only used when the receivers have been used for a very short period of time. Charging (quick-charge) takes a maximum of 2.3 hours. Green and red LEDs at the charging positions indicate the charge status of each receiver.

This suitcase is used to recharge receiver units type LBB 3432/10, LBB 3433/10, LBB 3433/15 and LBB 3434/10. Up to 56 infra-red receivers can be recharged, and the suitcase is also ideal for convenient storage and transportation of infra-red receivers.It has a universal mains input which adapts the unit to mains voltages between 90 to 264 Va.c. (47 to 63 Hz), and a mains loop-through facility which allows up to six suit-cases to be connected to a single mains socket in a loop-through configuration. Red and yellow status LEDs are present at each charging position. The red LED indicates that charging is proceeding normally, while red and yellow LEDs illuminated simultaneously indicate a receiver-battery fault. The receivers can be stored for as long as required in charging positions, so ensuring that the batteries are always fully-charged.
