ENTER and select the character. And so on. The name you enter will show on the opening
screen at startup if ‘Splash Name’ is ON (see below).
Beeper
There are six options available for the duration of the beeper sound: extra-long, long, normal,
short, extra short, no-key and quiet. As each option is selected the beeper makes the
corresponding sound. The NoKey selection eliminates the beeps when editing but allows alarms
to sound. Quiet means no sounds or alarms at all.
Contrast: Screen contrast setting
The higher the value the darker the screen.
Battery Warning
Sets the voltage at which a warning message will be announced, alerting you to “low battery”.
The voltage you choose depends on the minimum safe level for the battery size and type you
have installed in the transmitter. The transmitter will work down to about 6 volts, but you need
time to land and your battery may have a much higher minimum safe voltage (e.g., about 9.3v for
LiFe chemistry and up to 11v for LiPo). See the manual Introduction to the Hardware for advice
on batteries and settings.
Inactivity Alarm:
This reminds you to turn off the transmitter. If the transmitter is left turned on with no movement of
the sticks for the period of inactivity set here, this alarm will sound. Values can be from 1 to 250
minutes. To reset the timer simply move one of the sticks. To disable the alarm, set the value to
zero.
Filter ADC: Analog to Digital Conversion
The ARM processor in the 9XR Pro is 12-bit, giving 4096 resolution (compared to 10-bit, 1024
resolution for the 9X and 9XR AVR processors). Since the Ersky9x firmware uses 2048
resolution, conversion is necessary.
There are three options for the analog to digital conversion:
SING: Single conversion. This is the fastest process, simply reading the value once and dividing
by 2 to achieve the resolution required by the firmware.
OSMP: Oversampling. This option averages four consecutive values to smooth servo response.
It’s only slightly slower than SING and is the best choice for most users.
FILT: Filtered. This option averages over a longer time to minimize conversion noise and thereby
reduce servo jitter. It will, however, increase latency by about 10 msec.
Throttle Reverse
Only if you fly with the throttle “backwards” (i.e., with idle away from you and full throttle towards
you) should you set this to ON. It will also reverse the throttle warning on startup.
Minute Beep
Set this ON if you want a beep or announcement to sound every minute during timer operation.
Beep Countdown
Set this to ON if you want the timer to sound beeps or announcements during the last minute of
countdown.
