RSSI Calibration Procedure:
• Step 1 -Remove props
• Step 2 - Turn on the R/C transmitter and move the radio 3-6 feet away from
the QQ190™. Select Calibration and press Enter to set the Max. value (best
signal)
•Step 3 - Turn off the R/C transmitter and press Enter to set the Min. value (no
signal)
Crossre/EzUHF OSD Link receives and displays the numeric values directly from the
Crossre/EzUHF Rx, There is no calibration required when using these receiver types.
•
Battery
The QQ190™ will detect the voltage of battery (2S-6S) during the boot process. By
default, a textual warning will be displayed when the battery dips below a critical level
(default 3.5V per cell).
•
Alarm - Enable/Disable - Shows a warning when battery voltage reaches a
critical level
•
Level input - Auto/Manual - How to detect the number of battery cells/
voltage
•
Warning level - 0.0 to 99.9V - Set the threshold when a low voltage alarm
should trigger
•
Curr. Correction - 50 to 250% - You can use this function to calibrate your
current sensor if it is a little off. For Example, if you y a battery and the OSD
shows you you used 1000mAh but your charger let you charge 1200mAh, you
can set this value to 120% and the reading will match on the next ight
•
Backup Voltage - Disable/Enable - Enables the backup battery, if connected,
so the OSD/GPS can run while the rest of the system is down, e.g. to recover a
downed aircraft
•
General
Change how the HAM callsign is displayed, either Off, Always or Minutely. The exact
GPS coordinates can be displayed on the bottom screen to make it easier to locate
a downed QQ190™ by looking at any ground station recordings. (GPS Must be
installed to use this feature)
