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". The LCD will display "OFF", no LCD or backlight is lit up and the unit will be off. At Power Off the transmitter will store the last settings entered and re-display them at the next power on where it can be reprogrammed to any new Group/Channel or Volume level at the first time of use or anytime later. The factory default setting for Volume 0dB is same for all transmitters. These settings are optimal for most applications. 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 (43) to download pre-programmed channels from the receiver. Start programming by holding the IR LED Receptor about 6"-12" from the receiver's IR LED Window (4), then press the IR Sync Button (5) on the receiver to be used. When short pressing the ASC IR Sync Button, while the main menu is displayed, the IR LED will light up red for about five seconds. This indicates IR transmission is in progress and IR data is transferring during this period. Upon successful data transfer (usually in about three seconds) the IR LED stops and the transmitter's backlight will light up and the transmitter will transmit a radio signal on the same channel as the receiver. The Signal Strength and Diversity Indicators on the receiver's LCD display will then light up, indicating that the IR link is completed. Note: If procedure is not done correctly during the three seconds of active data transfer, the receiver and the transmitter do not link and transmitter's previous programmed channel remains unchanged. The IR link is infrared light and thus works best when this data transfer is accomplished in a light-shielded or darker environment. It may not be successful in a brightly lit area. If the transfer fails, repeat the procedure in a darker location or somehow shield the link from outside light to success-fully program the transmitter with the pre-programmed group and channel info from the receiver. Manual Programming (GRP/CH and Volume): The transmitter's frequency is set using the Set Button (42) and then the (Up) or (Down) Buttons (41). During manual programming, the selected function will flash for five seconds, or press the Set button to confirm the selection and the display will return to the main menu. To start, press the Set button once. The backlight on the LCD (40) will light up and the Group (30) icon will flash. Use the Up/Down buttons to change the group. When a group selection is finished, press the Set button again for the channel selection. The Channel Icon (31) will now flash. Again, use the Up/Down buttons to change the channel as desired. When the group/channel selection is done, press the Set button again to enter volume level input setting and then press Up/Down button to change in four steps from 00dB to -30dB (for loudest input) or press the Set button a second time to exit to the main menu. To change volume input level only, press the Set button three times to select the volume input level setting. Use the Up/Down to change in four steps from 0dB to -30dB (-30dB for loudest input). The level is preset 15
