Receiver Normal Operation; Add A New Frequency To The Next Open Channel - Lectrosonics IFBR1a Quick Start Manual

Receiver Normal Operation

1. Set the Frequency of the receiver to match the frequency of the trans-
mitter by using the two HEX rotary switches located on the side of the
receiver under the sliding door. The 1.6M switch is for "coarse" adjust-
ment (1.6 MHz per click) and the 100k switch is for "fine" adjustment (0.1
MHz per click).
2. Plug an earphone or headset into the 3.5mm jack. Be sure the unit has a
good battery.
3. Rotate the knob clockwise to switch the power ON (Do NOT hold the
knob in while switching power ON). The LED will illuminate. Rotate the
knob to set the desired audio level.
4. If channel frequencies have been stored in the memory, change channels
by pressing the knob briefly and release. The LED will blink the next
channel number (frequency) and the receiver will resume operation on
that channel. If no channel frequencies have been stored when press-
ing the knob to change channels, the LED will flash from green to red to
yellow to green, indicating no stored channels and the unit will resume
operation on the channel set by the switches.
5. Whenever the power is switched ON, the unit defaults to the frequency
set by the switches.

add a New Frequency to The Next Open Channel

Before operating a receiver, one or more IFBT1/T4 transmitters must be
placed in XMIT mode, with each transmitter set to the desired frequency and
connected to a proper antenna, audio source, and power source. The trans-
mitter frequency block must be the same as the receiver frequency block as
marked on each unit.
1. Position the receiver at a location within 20 to 100 feet of the transmitter
or transmitters.
2. With the power ON, depress the knob until the LED starts rapidly blink-
ing, then release the knob.
3. The unit goes into program mode and does a scan/search. Previously
programmed frequencies will be automatically skipped. When the unit
stops on a new frequency audio from the transmitter will be heard in the
earphone and the LED will stop blinking rapidly and will change to a slow
blink mode.
The unit is now waiting for an operator decision. You must now decide to
either SKIP or STORE the frequency (step 4 or 5 below.) Switching the
power to OFF without storing will delete the frequency.
4. To SKIP the frequency, depress the knob briefly and the scan/search will
resume.
5. To STORE the frequency into a channel memory, depress the knob and
hold it until the LED blinks the new channel number, then release the
knob. The frequency is now stored in an open channel.
6. The unit will continue scan/search for other frequencies. To store more
frequencies repeat steps 4 and 5 above. Up to 5 frequencies can be
stored in memory channels.
