3 BP24 UWB Body Pack Transmitter
3.1 Transmitter Controls
An On/Off power switch is located in the battery compartment.
The adjustable transmitter parameters are:
1. System ID (SYS) – Each transmitter must be assigned a system ID (1-9) that
must match the system ID set on the MCU3224
The transmitter will only transmit when it receives a sync pulse and
matching system ID from an active system. This will prevent users with
transmitters assigned the same channel slot on a different system from
interfering if they enter the coverage area.
Note: RP timing signals from separate systems must be RF isolated from
one another to prevent system timing contention in transmitters.
2. Channel Number (CHAN) – The channel slot assigned to the transmitter (01-
24.) Each transmitter in the system is assigned a unique channel number.
3. Input level (GAIN) – Adjustment of the audio input level (0 dB to 20dB in
2dB Steps).
The adjustable transmitter parameters are shown on a display located on the face
of the transmitter.
The display will only be illuminated when the user is adjusting the transmitter.
Pressing any button will activate the display for 10 seconds. After 10 seconds,
display functions will no longer be illuminated although the BP is functioning.
Pressing any button will light the display in order to check for power or operating
condition.
