Setting Up and Using Your AirLine System

8. Turn on the power to your transmitter (using its Power on-off switch); the "Power/Battery" LED will flash if the battery is sufficiently strong
(if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). If your system contains either a CR77 or
UM1 receiver, one of the "A/B Receiver" LEDs will light, showing you whether the (left) "A" or (right) "B" receiver is currently being used. The
CR77 / UM1 meter will also indicate the strength of the incoming RF signal.
9. Now it's time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down. If you are
using an AL1 transmitter, make sure that it is unmuted (its Mute switch should be positioned away from the arrrow). Then set the Volume,
Level or AF Level knob on the receiver fully clockwise; this is unity gain. If you are using an AL1 transmitter with the built-in microphone,
note that correct placement is critical to sound quality. We recommend that you place it as shown in the illustrations on this page— unob-
structed by clothing and either clipped to a shirt pocket or lapel, or worn around the neck on the supplied lanyard.
