Introduction

The SKY04X is a First Skyzone goggle with focus adjustment. The 1280*960 high-resolution screen offers vivid color and high contrast, allowing pilots to see more details during racing.

With the SteadyView receiver, it merges two signals into one, avoiding image tearing and rolling, which results in a more stable and clear image in challenging conditions.

The newly designed optics feature focus adjustment and a 46-degree Field of View, providing a more immersive FPV experience.

The new OS supports 10 languages, making the menu system easy to navigate. With a shuttle wheel and a new user interface, pilots can adjust settings by simply rolling the wheel without removing the goggles.

Diversity: A feature for receiving signals from multiple antennas.

SteadyView: Enhances image stability by merging signals.

Quick Start Guide

1. Install the antenna and faceplate.
2. Connect the battery to the goggles using the power cable. The goggles can be powered by a 2-6 cell LiPo battery. Press and hold the power button to turn on.
3. Focus adjustment: Move the focus adjustment wheel to focus. Close one eye and adjust the focus. You can access the OSD menu as shown in the template. Once the image is clear, repeat the process for the other eye.
4. IPD adjustment: Move the IPD slider until there is no double vision of the image.

Band /Channel / Receiver mode setting

1. Press the right wheel, then roll the right wheel to change the channel. Press the wheel again to switch to Band setting mode, then roll the wheel to change the Band. Press the wheel again to select diversity or Mix mode.
2. RF setting will quit the channel setting mode if no wheel operation for 3 seconds.
3. Hold the right wheel to pop up the search menu. Press the right wheel to start auto search. After searching all frequencies, the receiver will work on the strongest signal. Roll the right wheel to manually select channels. Hold the right wheel to quit searching.

Note: Some cameras may not follow standard NTSC/PAL signals, which can confuse the receiver in Mix mode, leading to dark images, color distortion, or rolling. Switching to diversity mode can resolve this issue.

Important: Automatic channel search may not always be accurate; manual channel selection might be necessary.

Volume Setting

• In all mode preview mode, roll the left wheel to adjust the volume.
• Volume setting is only effective for the earbud, not for AV OUT volume.
• The system does not save the volume setting, to prevent excessively high volume in AVIN or RF mode.

MODE MENU

• Short press the left wheel to open the mode menu.
• RF normal: Standard 48 CH receive mode.
• RF Racing: Receiver operates only on RaceBand.
• RF Third-Party: Goggle buttons cannot control the external receiver, and the OSD cannot read the band/channel of the receiver.
• AVIN: Supports automatic switching between NTSC and PAL system formats. The receiver module is automatically turned off to save power.
• HDMI IN: The receiver module and video recording module are automatically turned off to save power.
• Playback: Allows users to review DVR files.

PLAYBACK

• In playback mode, roll the right wheel to select the DVR. Short press the right wheel to play and pause.
• Use the left wheel to adjust the volume.
• While playing a DVR, roll the right wheel to fast forward or fast backward.
• Press the Right button to quit DVR.
• Press the Left button to delete DVR.

Setting

• Short press the right button to open or close the system menu.
• Roll the right shuttle wheel to navigate. Press the wheel to enter sub-menus.

Head Tracking

• The head tracking button is located on the right side of the goggles.
• The gyro requires an initialization period. When powered on, keep the goggles horizontal and stable. A beep indicates initialization is complete.
• Hold the HT button to reset the PPM signal to the center. The goggles will beep when the button is pressed.

Note: Disabling the Headtracker can save initialization time, speeding up goggle boot time.

Image

In the image setting menu, users can select from standard, bright, vivid, soft, and 3 custom profiles. Brightness, Contrast, Saturation, Hue, and Sharpness can be adjusted to suit different environments. The image settings for the 4 pre-set files cannot be changed.

DVR

• The left button serves as the record and stop button.
• The built-in DVR uses H264 encoding. A Class 10 SD card is recommended, supporting up to 128GB.
• The SD card must be formatted to FAT32. Users can format the SD card via the system menu.
• The video recording function is available in both RF Mode and AV IN Mode.
• By default, sound recording is enabled. The "sound recording" function can be turned off in the system menu to record video only.
• Automatic recording: When enabled, recording starts automatically if a video signal is detected. Recording can also be manually stopped by pressing the REC button.
• <Auto&Follow>: The DVR automatically starts recording when a video signal is present and stops 30 seconds after the signal is lost. If the signal returns, recording resumes.
• <Follow>: Press the REC button to manually start recording. Recording stops 30 seconds after the signal is lost but resumes automatically when the signal is present. Pressing the REC button again manually stops recording to save SD card space.
• Cyclic recording: Overwrites older recordings when storage space is full (can be turned on or off).
• The video recording file is automatically divided into multiple files. Video length can be set to 5, 10, 20, or 30 minutes per file in the system menu. The default is 30 minutes per file.

Important: If power is disconnected during video recording, the DVR may be damaged. The goggles have a repair function. After entering Playback mode, the last DVR file will be automatically checked and repaired if damaged.

Display

• In the Display setting menu, users can set the topbar OSD time, disable OSD timeout, or keep the OSD always on.
• Users can set the RSSI icon to display Icon + percentage, Icon, Percentage, or Disable, and adjust the vertical position of the RSSI.
• The luminance of the LCOS screen can be adjusted in 8 stages (default is 5). It is generally not recommended to set the brightness too high unless the image is dim.
• Sleep MODE: To prevent screen burn-out, the goggles have a sleep mode. The sleep mode can be set to 1, 3, or 5 minutes (default is 3 minutes). When sleep mode is enabled, the goggles detect movement using the headtracker gyro. After a preset time of stillness, a buzzer will sound, and after 10 seconds, the goggles will enter sleep mode, turning off the screen. Moving the goggles will exit sleep mode.
• In the Display setting menu, users can change the aspect ratio to 4:3 or 16:9 (default is 4:3). Users can also switch to a small FOV mode, which crops the image at the edges.
• When sleep mode is triggered, other goggle functions (receiver, DVR, etc.) remain active.

To quit Sleep mode: Move the goggles when you hear the beep.

SYSTEM MENU

• Power supply menu: Select battery type (2S-6S) to ensure accurate battery capacity display.
• Voltage calibration: Allows adjustment of voltage within a ±0.9V range. Use a multimeter to measure the loaded battery voltage and adjust using the shuttle wheel.
• RSSI Calibration: Calibrate the RSSI by removing the antenna, turning off the VTX, selecting 'yes', and waiting for the goggle to beep upon completion.
• System Language: Select from English, French, German, Russian, Italian, Portuguese, Spanish, Chinese, Japanese, or Korean.
• The built-in fan helps defog and dissipate heat. Fan speed can be adjusted in the system menu. Press the POWER button to start/stop the fan.
