2) Press the ENTER key. The BATTERY menu will be displayed and ALERT VOLT 4.6v will
be highlighted.
3) Press the ENTER key, then scroll UP or DOWN to choose the desired Low Voltage Alert
alarm value. Increasing the Low Voltage Alert alarm value will cause the Low Voltage
Alert alarm to sound at a higher voltage and decreasing the Low Voltage Alert alarm
value will cause the Low Voltage Alert alarm to sound at a lower voltage.
BATTERY ALERT VOLT setting range is 4.1v to 9.0v. The default setting is 4.6v.
The Low Voltage Alert alarm voltage value cannot be set lower than the Low Voltage Limit alarm voltage value.
1) From within the SYSTEM menu, scroll UP or DOWN to highlight the BATTERY menu.
1) From within the BATTERY menu, scroll DOWN to highlight LIMIT VOLT 4.4v.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired Low Voltage Limit
alarm value. Increasing the Low Voltage Limit alarm value will cause the Low Voltage
Limit alarm to sound at a higher voltage and decreasing the Low Voltage Limit alarm
value will cause the Low Voltage Limit alarm to sound at a lower voltage.
Changing the Low Voltage Limit Alarm Value:
The Low Voltage Limit alarm will sound to indicate the transmitter batteries are dangerously low and should be replaced or
recharged right away. The Low Voltage Limit alarm cannot be cancelled. When the Low Voltage Limit alarm sounds, you should
stop use as soon as it's safe, then replace or recharge the transmitter batteries.
BATTERY LIMIT VOLT setting range is 4.0v to 4.9v. The default setting is 4.4v.
WARNING:
Continuing to use the transmitter after the Low Voltage Limit alarm sounds can result in loss of control of your
model. When the Low Voltage Alert alarm sounds, stop use as soon as is safe, then replace or recharge the transmitter batteries.
Changing the LCD Contrast Value:
1) From within the SYSTEM menu, scroll UP or DOWN to highlight the LCD menu.

SYSTEM
The LCD menu allows you change the contrast of the LCD, the Backlight Mode and the Backlight On-Time. Changing the
Contrast settings can make it easier to view the LCD in different lighting conditions and changing the Backlight Mode and
Backlight On-Time affects how the Backlight is turned ON and how long the Backlight stays ON.
IMPORTANT:
Leaving the LCD Backlight ON at all times will Increase battery consumption. In addition, Decreasing the
Contrast value near the Lower limit can result in the LCD text becoming impossible to read. Be careful not to set the Contrast
value too low.
