Rev A


Iftron’s new ClearView video receiver is the result of a successful, multi-year, intensive video technology development. Designed to vastly improve on standard definition video, ClearView is the greatest advance in the state of the art in many decades. The proof is video with so much less of the glitches, dropouts, fades and horizontal tearing you are accustomed to, that it’s absolutely amazing - especially so in difficult environments like near large metal or concrete objects, the ground, in wooded areas, or even indoors.

ClearView’s extreme innovations also include an ultimate sensitivity far beyond ordinary receivers and an exclusive receiver side OSD featuring the world’s first OSD Spectrum Analyzer. 

This Document Is A Work in Progress.

Please continue to check this document for changes and additions. 

This is a quick start document that will be added to as time allows, until it becomes a full user manual. Feel free to experiment with the various receiver settings. You can’t hurt the receiver and we have included an option in the menu system to return to factory defaults.

Our goal is your success. If you have any questions or comments on this manual or the receiver itself, please feel free to email us at:

Note: If needed, please feel free to pull the plug and start over. You won’t hurt anything. Later, you will be shown where you can easily reset the unit to all the factory defaults. However, any frequency choices you have made will be saved.


You may run ClearView with two different types of antennas on each antenna connector (asymmetrical setup). However ClearView is not a diversity receiver and does best when both antennas are the same type. ClearView works with both omni and directional antennas. If you are using directional antennas, we suggest that you point them in the same direction. If you are racing or doing any other type of short to medium range flying, asymmetrical antenna setups will not be necessary and may work against you. We suggest that you experiment.

Using the System Pushbutton:

 Very Important:  Throughout the menu system:

A press and hold from live video will bring up the Information Screen

A  short double-press  from live video, will bring up the menu.

A  short press  will advance to the next menu choice.

A  long press  will accept the presently highlighted choice.

Powering Up:

A short press will turn the receiver on. The first time you power up, you may be asked to choose your display type, either NTSC or PAL. short press to select and long press to accept your choice.

Tip: If your receiver is set to the wrong video standard for your camera and/or monitor, your picture may roll and this may make changing the receiver video standard difficult or impossible. To remedy this, first insure that your camera or video source standard is consistent with your monitor setting. Next, hold the receiver red button down while applying power. This will automatically flip the receiver standard from NTSC to PAL (or back). This should help you establish a stable picture. Confirm your setting before exiting this screen.

From thereafter on power up, or until changed in the main menu, the receiver will go directly to the spectrum analyzer app. Note that the highlighted choice will already be on ‘EXIT.’ Long press to exit to live video or continuous short presses to navigate around the screen. See Spectrum Analyzer App for more on this novel feature.

Note: You can easily change the receiver to start up with live video instead. Select the “HELP” choice in the spectrum analyzer to make this change. You can also change the startup default screen in the main menu.

Note: Consult factory for delivery of receivers that power up themselves upon application of power.

Entering the Menu System:

1. Entering Quick Info Screen: During live video, press and continue to hold the button to display all the available data such as: receiver voltage, frequency, signal strength (RSSI), etc. Release to instantly return to live video.

Note: If you continue to hold the button in the Quick Info Screen, receiver will warn that it is about to shut down. Release button to return to live video or continue to hold to shut the receiver down.

Note: If receiver is accidentally shut down with the button, a quick press within 4 seconds will instantly restore live video without a reboot delay.

2. Entering The Main Menu System: From live video, a quick double-press of the button will bring up the menu system.

Tip:  Throughout the menu system, watch the bottom line on the screen for additional information relating to the current menu choice.

Changing The Frequency:

The receiver is capable of accessing up to 32 frequencies stored in working memory. The 32 most common frequencies are already stored for your convenience. You can easily reduce the number of frequencies in working memory, to only those that you commonly access. See the “Programming Frequencies” section on how to reduce the number of frequencies to a working group and how to program custom frequencies. For your convenience, we have preset the custom frequencies to the “race band.” Feel free to enable or change them. Remember, if adding a custom frequency, you will need to make room for it in the 32 channel memory by disabling one in the non-custom frequencies, assuming that you have not already disabled some.

There are two ways to change the present frequency.

  1. Enter the main menu with a double press from live video. Select “Change Frequency” and continue to short press until your desired frequency is highlighted. Then long press to select it, or simply wait a few seconds and the receiver will automatically tune and return to live video.

  1. Select the desired frequency from the Spectrum Analyzer app. See “Spectrum Analyzer”section below for details.


From live video, a very long press will do a soft shutdown. There are a few internal pieces of data that will get stored when you shut down with the button. These only influence how long the receiver takes to lock onto your signal when you power up the next time. Powering down by pulling the plug is also fine. You won’t hurt anything and the difference in lock time when powering back up is pretty small - so no worries either way.

Spectrum Analyzer App:

More than just a clever gimmick, the On Screen Spectrum Analyzer enables you to:

  • See what other frequencies are in use
  • Tell how strong other transmissions are
  • Select a frequency that you might wish to receive*
  • Tune instantly to any frequency you are observing, as long as it is already in memory.

*Note that the SA has two modes: a “frequency” mode that displays only the frequencies in your working memory, and a “spectrum” mode that displays the entire band in even increments.

As shipped for the factory, the Spectrum Analyser (“SA” for short) is the first screen you will see after bootup. You can change this behavior by navigating to “help” with short presses, then long-pressing to select  “help” where you will be able to choose whether the receiver boots to live video instead. You can also change this choice anytime, both here and in the main menu.

Continued short presses of the button will advance a pointer at the bottom of the screen, one channel for each press. Note that each frequency that the pointer lands on will show the frequency and the approximate power level, if any transmission is found.

To instantly tune to a given frequency, position your pointer at the frequency you want and then long press. The receiver will tune to that frequency and immediately exit to live video.

If the “Spectrum” mode is selected, long pressing will tune to the nearest frequency in working memory, to the frequency you are pointed at.

Enabling / Disabling Frequencies:


Most users do not need to access all frequencies stored in the receiver. To streamline access to the frequencies you normally use, the receiver contains a working memory that can be programmed to show only the frequencies you choose.

In the Frequency menu, navigate to each frequency and long press to change each box to: Filled for Active, or Empty for Inactive. Your choices will be stored for future use or until you change them.

■  (filled box) = Active frequency

□  (empty box) = Inactive frequency

Note: The Spectrum Analyzer will display only your Active Frequencies when in Frequency mode.

A Word About Antenna Deployment Strategies:

Do not run ClearView with different types of antennas on each antenna connector  (asymmetrical setup) when the option menu is set to the “ClearView” mode. ClearView is not a diversity receiver and does best when both antennas are the same type. If your antennas  are directional,  aim them in roughly in the same direction. If you are racing or doing any other type of flying, asymmetrical antenna setups will not be necessary with ClearView and will work against you.
