be on, indicating a received signal from the transmitter. Adjust the volume of the receiver per Connecting Audio Output.

Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.

Note: The RF Signal meter and the Diversity A/B indicator on the receiver’s LCD display should be “On” in normal operation.

BT-1KU Bodypack Transmitter (LT, LT/HM or GT)

Setting up the Transmitter

The BT-1KU bodypack requires two AA size batteries to operate. To install the batteries into the battery compartment, lift the Battery Compartment Door (46) by grabbing the two spring-loaded locking tabs and pull out, exposing the Battery Compartment (45). Insert two fresh AA batteries according

to the correct polarity as indicated on the transmitter body. Close the battery cover, ensuring the cover is snapped shut. Fresh alkaline batteries can last provide up to 8-10 hours of operation, but in order to ensure optimum performance it is recommended that the batteries be replaced after 6-8 hours of use or as indicated necessary by the flashing Battery Meter (40).

Use Audio Input (33) 3.5mm locking mini jack for connecting the audio input cord from lapel mic (LT), Headmic™ (LT/HM), or instrument (GT), depending on which version transmitter is being used. Secure the connection to the cable by lining up the slot of the 3.5mm mini connector and turning the ring to securely lock in.

Powering the Transmitter On/Off

To turn on the transmitter, slide the Power Off/Mute/On Switch (34) to the Mute (middle) position (transmitter on, audio muted). The LCD backlight will light up. The unit is now on. After ten seconds the backlight will automatically turn off. The Group Icon (37) and Battery Meter (40) remain on in normal operation.

As many of the five LCD battery levels should stay lit as possible, indicating usable battery strength. As the batteries weaken, fewer of the level indicators stay lit until only one bar shows, which will then flash to warn that the batteries are now too low and should be replaced as soon as possible. To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the Off/Mute/On switch to Mute and then Off. No LCD or backlight is lit up and the unit will be off.

Programming the BT-1KU to the Selected Channel

The transmitter can be programmed to the same frequency as selected for the receiver, either via automatic synchronization using the IR Sync function or manually on the transmitter itself.

IR Sync Programming:

Use the wireless IR LED Receptor Sensor (41) to download pre‑programmed channels from the receiver (see Selecting the W-1KU Receiver Volume Level/Group/Channel and Selecting the BT-1KU Transmitter Group and Channel). Start programming by holding the IR LED Receptor Sensor about 6”-12” from the receiver, then press the IR Sync Button (11) on the receiver. The red IR LED (10) on the receiver will flash once after one second indicating IR data transfer, and then once
