Normal Display
When the power switch is turned on, the LCD screen will
display the channel selected for signal transmission and
transmitter battery pack voltage as shown below. This
screen is referred to as the Normal Display. Pressing the
Channel key will switch the display between the trans-
mitting channel and model name.
Note: If any of the electronic trim buttons are
moved while in this screen, the screen will auto-
matically change to display the trim in use. This is
called the Direct Trim mode. For more information
on the feature, please see page 29 of this manual.

Low Battery/Lithium Battery Backup
When the voltage of the 8 “AA” batteries drops below 9.0V,
the XS3’s display screen will alternate between the Normal
and Low-Battery screen (BAT), and a continuous beeping
will occur, indicating that the batteries need to be replaced
before further use. The Low-Battery screen is active during
any operating modes.
Memory Backup
If the Memory Backup screen appears, this indicates the
possibility of a ROM problem or the lithium battery is dead.
If you switch the power off and on again, but the transmitter
is in the default mode with all data lost, it is strongly sug-
gested that the XS3 transmitter be returned to the Horizon
Service Center for servicing (see Warranty Information,
page 37).
Lithium Battery
Your XS3 radio system is equipped with a five-year lithium
battery backup system. This system is designed to protect
and retain all radio programming in the event that the
transmitter batteries drop below the required 9.0 volts, or
the transmitter battery case is removed during battery
changes. If after five years it becomes necessary to replace
the lithium battery, return your system to the Horizon
Service Center (see address, page 37) for repair.
