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 31 of this manual.
Display Screens
Up-Timer
Note
: If the Lap-Timer is enabled, an up-timer display
may alternatively be selected over the normal display
screen by pressing the Channel key. Pressing the
Channel key again will scroll back through the channel
select and model name screens. (For more information
on this feature, please see page 28.)
Low Battery/Lithium Battery Backup
When the voltage of the 8 “AA” batteries drops below 9.0V,
the XS3 PRO’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
suggested that the XS3 PRO transmitter be returned to
the Horizon Service Center for servicing (see Warranty
Information, page 39).
Lithium Battery
Your XS3 PRO 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 39) for repair.
