Normal Display
When the power switch is turned on, the LCD screen will
read as shown below. This screen is referred to as the
Normal Display.
Note: If any of the electronic trim buttons are moved
while in this screen, the screen will automatically
change to display the trim in use. This is called the
Direct Trim mode. For more information on the feature,
please see page 30 of this manual.
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 bring back the model name.
(For more information on this feature, please see
page 27.)
Low Battery/Lithium Battery Backup
When the voltage of the 8 "AA" batteries drops below 9.0V,
the XR3i'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.
Lithium Battery
Your XR3i 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 for repair (see address, page 39).
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 XR3i transmitter be returned to the
Horizon Service Center for servicing (see Warranty
Information page 39).
