User manual: First contact
After powering radio (and recovering EEPROM memory, if needed) you will see main screen, which should looks similar to this:
This is just the default home screen, which can be configure according your needs. Currently you can see the battery voltage, clock (elapsed time from power on the radio) i model name (START). At the edges, it shows the location of sticks and trim (these markers next to bars). The inscription such as "0079/0640" is information about current transmitter computation speed. it means that PPM frame is sent 79 times per second (in this example), and the main program loop (ie, reading sticks and counting all mixers) is done 640 times per second. This single "5" means the state "Internal switches." You can change it to 6 or 7 by three-position toggle switch on the transmitter. Temporarily setting all the switches I will call later "internal state" of the transmitter.
To enter menu, press and hold the MENU key more than 1 second.
So let me explain the basics of keys, navigate menus and change settings. The keyboard looks like this:
Notice the conversion of + and - keys than the original!
UP and DN keys
Keys on the left: UP (Up), DN (down) are used to move the highlight (displayed as reversal of colors) on the menu and while editing options. The element that is highlighted, is focus for all the activities of other keys. For example, if you highlight menu item then you can press MENU key to open the menu, if value is highlighted then keys keys + / - allow to change it.
If the last item is selected, the DN (down) key will take you to the first element. Similarly, using the UP key on the first element will take you to the last element.
- and + keys
First, notice that these keys are reversed! This software considering left key as - (Minus), and right key as + (plus). These keys are used to change the value / settings for the selected item. You can hold the key to get the effect of auto-repeat. For example, if you hold down + key more than 1 second, the selected value will be increased at a rate of about +30 per second. Most of the adjustable value can be "rewound", ie if the value reaches maximum, it starts from the minimum value.
Additionally, the keys + / - drive a menu, such as press MENU and EXIT, but excluding entrance to the main menu and returning to menu after selecting an option.
It is used to accept the selected action (such as accessing the menu, save the settings, etc) or recall of the current reading of the value in the selected field.
Additionally, in some places it is possible to activate a specific function when holding MENU key (more than 3 seconds) before releasing. An example is the reversal of the direction the servo or stick during the calibration procedure or reinitialization clocks in clock configuration.
It is used to exit the current menu or option. Note, pressing EXIT key before saving, will cause loss of your changes and recall settings before changes.
This key is particularly useful if we open something by mistake, or you just want to test some setting, and then restore the previous state.
Main menu - the menu button is pressed more than 1 second.
All the menus look similar. The place in which we are is determined by the vertical inscription on the left."BASIC" menu:
BASIC - the menu includes features from which you should start. It contains basic information about the model as its name, the radio resource consumption, servos centering option and visualization of outputs. If you load some already prepared configuration from the SD card, in this menu you should find everything you need to adjust it to your needs. You can configure the servo centering, rearrange inputs and calibrate inputs from slave transmitter (PPM)."MODEL" menu:
MODEL - the menu includes all the features that determine behavior of the model. Here you can define any mixer, set the clock (timer), identify ways to transitions between states (virtual switch settings) and set the appearance of the main screen."MEMORY" menu:
MEMORY - menu allows you to read and write the model from / to Memory Card. Here you can also delete model configuration and begin configuration from the default settings."CONFIG" menu:
CONFIG - menu contains the settings that are not dependent from the loaded model. Changes made here are not saved with the model, and are valid for all models loaded into the radio. This menu allows you to calibrate sticks and knobs, set alarm level for the battery, adjust LCD contrast, and to determine the how to communicate with radio module and set trim keys behavior. Additionally, you can switch the radio into "Pro mode" (not recommended for beginners).
To help you find the options I will use following notation: MODEL->Timers, which means that you should choose from the main menu MODEL sub menu, accept it with MENU button, then select the "Timers" and again accept it with MENU button.
