Checking Transmitter Batteries (Figure 35)
1. Turn the transmitter power ON/OFF switch to the ON position.
2. Observe the battery fuel gauge displayed on the transmitter screen and on the
right side of the receiver screen. Battery power level is indicated by the number
of black segments displayed. As transmitter batteries are consumed, the dis-
played segments will gradually disappear.
NOTE: The dc to dc converter functions keeps system voltage constant as battery
voltage declines, ensuring superior audio and RF performance.

PROGRAMMING THE TRANSMITTER
The Group/Channel setting on the U1 and U2 transmitter display can be pro-
grammed to meet the requirements of a particular installation. You can also lock the
display and the power on function to prevent accidental changes. Instructions for
programming the transmitters are presented in the following paragraphs.
Changing Transmitter Group/Channel Settings
1. Turn the transmitter on by sliding the transmitter power ON/OFF switch to the ON
position. The existing Group and Channel settings will be automatically dis-
played.
2. Open the battery compartment. This will expose the MODE (left) and SET (right)
buttons, as well as the GAIN control and the batteries, as shown in Figure 37.
