BATTERY MENU {TRANSMITTER LOW VOLTAGE ALERT AND LIMIT ALARMS}
SYSTEM
Changing the Low Voltage Limit Alarm Value (Custom), Continued:
2) Press the ENTER key, then press the UP or DOWN keys to choose the desired Limit
Voltage value. Increasing the Limit Voltage value will cause the Low Voltage Limit
alarm to sound at a higher voltage and Decreasing the Limit Voltage value will cause
the Low Voltage Limit alarm to sound at a lower voltage.
The Limit Voltage value
cannot be set higher than the Alert Voltage value.
BATTERY LIMIT VOLT setting range is 4.0v to 4.9v. The default setting is 4.4v.
WARNING:
When using a Lithium battery in your transmitter, NEVER allow the battery to discharge below 3.0V per cell (LiFe)
or 3.3V per cell (LiPo), or damage to the battery can occur, which can also result in damage to the transmitter, or even
your home or your person, if severe enough.
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.
LCD MENU {LCD CONTRAST AND BACKLIGHT OPTIONS}
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 becoming nearly impossible to read. Be careful not to set the Contrast
value too low.
Changing the LCD Contrast Value:
1) From within the SYSTEM menu, press the UP or DOWN keys to highlight the LCD
menu.
2) Press the ENTER key to open the LCD menu. CONTRAST 15 will be highlighted.
3) Press the ENTER key, then press the UP or DOWN keys to choose the desired Contrast
value. Increasing the Contrast value will Increase the contrast of the LCD and
Decreasing the Contrast value will Decrease the contrast of the LCD.
LCD CONTRAST setting range is 0 to 30. The default setting is 15.
Changing the LCD Backlight Mode:
The LCD Backlight Mode determines how the LCD Backlight operates. When set to OFF, the LCD Backlight will be turned OFF.
When set to KEY-ON, the LCD Backlight will turn ON when a key-press is made. When
set to ALWAYS, the LCD Backlight will stay ON at all times.
LCD LIGHT-MODE setting range is OFF, KEY-ON and ALWAYS. The default setting is KEY-ON.
1) From within the LCD menu, press the UP or DOWN keys to highlight LIGHT-MODE
KEY-ON.
2) Press the ENTER key, then press the UP or DOWN keys to choose the desired LCD
Backlight Mode value. Choose from OFF, KEY-ON or ALWAYS.
Decreasing the LCD Contrast value too much will make the LCD nearly impossible to read. We do not suggest using
an LCD Contrast value lower than 7.
