IFBR1B Features

On/Off and Volume Knob
Turns unit on or off and controls headphone audio level. When the IFBR1B is first turned on, the firmware version will display briefly.

Battery Status LED
When the battery status LED glows green, the batteries are good. The color changes to red at a midpoint during the runtime. When the LED begins to blink red, only a few minutes remain. The exact point at which the LED turns red will vary with battery brand and condition, temperature and power consumption. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time.

RF Link LED
When a valid RF signal from a transmitter is received, this LED will light up blue.
Headphone Output
A 3.5 mm mini phone jack accommodates a standard mono or stereo type 3.5 mm plug. The unit will drive low or high impedance earphones. The jack is also the receiver antenna input with the earphone cord acting as the antenna. The cord length is not critical but must be at least 6 inches minimum.
USB Port
Firmware updates via Wireless Designer are made easy with the USB port in the battery compartment.

Installing the Battery

An attached sliding door makes battery installation easy. The USB port is located in the battery compartment. Slide the battery compartment door open, drop the battery in so that the connectors match and slide the battery door closed.

Battery Charging

The receiver operates on a 3.6 V rechargeable battery that will provide about six hours of operation per charge. CAUTION : Use only Lectrosonics LB-50 supplied battery (p/n 40106-1).
The optional battery charger kit provides a folding NEMA 2-prong plug on the charger, and will operate from 100-240 VAC sources. The LED glows red during charging and turns green when the battery is fully charged. The kit includes a Euro plug adapter and vehicle auxiliary power adapter cord.
