LR-100 Programming
To make setup adjustments, remove the two hex screws that secure the front panel security cover.
Setup VU Meter
The front panel VU meter indicates the audio level of the OUTPUT signal. When making input audio level
adjustments, ensure that the red LED does not illuminate.
Input Audio Levels
Proper adjustment of input levels is critical to the proper operation of the LR-100.
Receiver Audio Level Adjustment. Under normal audio conditions adjust the receive audio level to meet the
output level needs of your installation. Make sure that the red LED on the VU meter does not illuminate.
Auxiliary Input Level Adjustment. Under normal audio conditions adjust the receive audio level to meet the
output level needs of your installation. Make sure that the red LED on the VU meter does not illuminate.
Selecting SQ ON or OFF
See Listen SQ™ on page 15. If the transmitter that is broadcasting to the LR-100 is SQ capable, make sure the SQ
switch for the transmitter and the LR-100 is turned ON. If not, the SQ switch should be turned OFF.
Channel Selection
Select the most appropriate channel by pressing the UP or DOWN button (see Channel Selection on page 16).
You can also press the SEEK button and the unit will SEEK for the strongest RF signal. The unit may stop on a
channel that is close to the actual broadcast channel, in which case the channel will sound noisy or distorted.
Simply press SEEK again until you find the clearest operating channel.
To Lock Into Only One Channel: press and hold the SEEK button for 5+ seconds to lock a receiver into the
currently tuned channel. Press and hold the button again to unlock.
NOTE: It is highly recommended to lock the channel after installation to prevent accidental channel selection.
Programming
In some cases, you may choose to give users the ability to select multiple channels. For example, let’s say you are
using the LR-100 for language interpretation. In this example, channels A, E and I are three different languages.
You can use the LR-100 programming feature to lock out all but the three channels used in this example. By
pressing the UP or DOWN button, the user can select between the three channels.
To Lock Out Channels in the LR-100:
Simultaneously press and hold the UP and DOWN buttons. You will notice the PGM indicator on the LCD
indicating you are in the programming mode (the unit will go out of the programming mode if you don’t press
a key for 10 seconds).
Use the UP and DOWN buttons to select the channels you want to lock out.
As channels are displayed on the unit, those channels that are locked out from user access will be indicated
by the L/O symbol on the display. When a channel is locked out, the LR-100 will skip over that channel when a
user is tuning the unit. Press the SEEK button while in program mode to lock out a channel (lock out means the
channel will NOT be displayed to the user). To reverse the lock out process, press the SEEK button on locked
out channels.
When you have completed programming the unit, don’t press any key for 10 seconds and the unit will exit the
programming mode.
