Checking Transmitter Battery Power

With the transmitter turned on, observe the Battery Level icon on the display. The number of shaded bars on the icon indicate
the approximate amount of battery life remaining, as shown in Figure 23.
NOTE: Stated battery life is based on a 9V Duracell alkaline battery. For details on other battery types, refer to the "Battery
Life" paragraph, or go to the Shure web site at www.shure.com and refer to the FAQ section. Once the empty battery icon
appears, the tone key turns off and the receiver will mute.

ULX1 Bodypack Transmitter Attenuation Settings

If using a lavalier microphone, make sure the Attenuator switch is in the 0 dB position. If using an instrument adapter cable,
slide the Attenuator switch to the –20 dB position. Refer to Figure 24.

2. If necessary, press the transmitter SET button to advance the Group number until it matches the Group number on the
receiver display.
