Quha Zono and Zono 2 are made for everyone who wants to use an accurate head mouse or can’t use desktop computer mice. Typically the users are people with

• Tetraplegia
• Dysmelia
• Amyotrophic lateral sclerosis (ALS)
• Multiple sclerosis (MS)
• Repetitive strain injury (RSI)
• Muscular Dystrophy
• Cerebral palsy (CP)

Quha Zono and Zono 2 are Class I Medical Devices and comply with the EU Medical Device Regulation (MDR) 2017/745.

Yes, Quha Zono and Zono 2 are compatible with Apple computers with macOS operating system. Quha Zono is also compatible with iPads and iPhones.

On a Mac computer the Quha Zono is a plug-and-play mouse device and doesn’t require any settings to be made. You plug the USB receiver into a USB port, turn on the power and it works.

If you wish you can change the mouse speed on the System preferences/Mouse. The more advanced settings are done using the Zono Setup and Zono Installation applications on a Windows computer. The settings are stored on the mouse, so these changes can be done on any Windows computer and the settings are remembered when the mouse is moved back to a Mac computer. At this point there is no native macOS application for changing the Quha Zono settings.

Quha Zono has several advantages compared to all competitive products on the market. The most important features are listed below.

There are several ways to make a click. Please consult the below table to find the most suitable option for you.

The double-click assistant stops the cursor for a short time period after a click, making it easier to click second time without moving the cursor between the clicks. Thus, the double-click assistant will not make the double-click directly, but helps the user to do it more easily.

There are many possibilities:

• Windows: The best and the most versatile option is to use Quha Dwell software. Other dwell clickers are also compatible with Quha Zono and Zono 2.
• Mac: Dwell selection functionality is part of the accessibility settings in System Preferences -> Accessibility -> Keyboard -> Accessibility Keyboard -> Options. Tutorial video available.
• Chrome OS: Dwell selection can be activated in Accessibility -> Automatic clicks
• Android: EaseMouse application can be purchased from Play Store or from Quha.
• iPad: Settings App -> Accessibility -> Touch -> AssistiveTouch > Dwell Control. Tutorial video available.

The easiest way to scroll a window is to use a dedicated switch such as Quha Sento or Quha Pufo+. Move the cursor to the area that you want to scroll, drag in the direction you want to scroll to and release dragging.

You can also use dedicated automatic scrolling software to scroll a window. Software can be downloaded from Google Play Store. For example the following apps can be used.

• Automatic Scroll
• Tap Scroll

The vibration attenuation filters are all based on different mathematical algorithms.

Algorithm 1 removes continuous vibration by slowing down the changes of the mouse speed. It makes the movements smoother, though also less accurate.

Algorithm 2 is a generic filter, which removes both vibration and rapid movements.

Algorithm 3 removes sudden fast movements.

Please feel free to explore all vibration attenuation options to find the most suitable option for you.

The OK and Apply buttons are purposely left out. The settings are stored in Quha Zono or Zono 2 mouse right after they are made on the Quha Zono setup software. This way it is easy to see the effect of the setting immediately making it easier to find the correct settings for the user.

Quha Zono and Zono 2 have a built in energy saving feature. Normally Quha Zono or Zono 2 responds immediately to any movement by the user. When the mouse has been stationary for about 10 seconds, it automatically starts saving energy to maintain maximum usage time. When the user moves the mouse again, the mouse automatically resumes standard operation. There may be a small delay in the cursor movement when this happens.

Quha Zono shows a blinking green light on the power button when charging is ongoing. If the light is not blinking, it means that the mouse is not charging. There can be multiple reasons for this.

1. The battery is already full.
2. The USB charging cable doesn’t provide charging current. The most common reason for this is the USB charging cable being connected to a USB port without power. Most modern computers have power saving features that turn off power on the USB ports when the computer is sleeping. Please connect the charging cable to a USB port that is always on. Recharging the Quha Zono battery from empty to full takes about 4 hours. Common USB chargers can also be used to charge Quha Zono.
3. The USB cable is defective.
4. If these measures do not solve the problem, please contact Quha support.

Yes. You can order a Quha Zono or Zono 2 with multiple USB receivers to be used with several computers or mobile devices. For example, if you use a computer in the living room and a tablet in the bedroom, you can connect the USB receivers in both devices and use them with one Quha Zono or Zono 2 mouse. However, you should turn off the device that you are not using if it is within the usage range, because otherwise the mouse movements and button clicks are received by both devices.

The Quha Zono mice have a motion sensor that detects the mouse movements and transforms these movements into cursor motion. The motion sensor is a highly accurate electric component and is affected by ambient temperature among other things. On those very rare occasions when the cursor starts to “drift”, the device can be calibrated by holding the mouse stationary for a few seconds. The easiest way to do this is to place the mouse on a table while it is on. The drifting is then automatically removed in a few seconds.

Readjusting the mouse by pushing the mouse cursor off screen is the standard way of repositioning the mouse cursor. If you notice your head is not in a comfortable position when the cursor is in the middle of the screen, turn your head so that the cursor moves to the edge of the screen and beyond. The amount of head movement needed depends on the mouse speed settings and you’ll quickly learn to reposition the cursor by experimenting. The repositioning movement corresponds to lifting and moving a table mouse when it is near a table edge. As the Quha Zono doesn’t use a fixed reference point or position to operate, sometimes it is necessary to make the repositioning movement.

Quha Zono has a rechargeable battery that provides approximately 30 hours of active usage time. The most common reason for Zono turning itself off before 30 hours have passed is partially charged battery. Please check that the Zono battery is charged using a USB port that is powered when the computer is on standby / powered off. Powered USB ports are usually marked with discernible colours or other markings.

There are several possible causes for this.

1. Is the Quha Zono mouse turned on? The cursor is visible only when the mouse is turned on. The Quha Zono power button has a light indicator that blinks every few seconds when the device is on.
2. In case you have Zono 2, have you paused the cursor? Try to remove and re-plug the USB Receiver. Please refer to the user manual for more information.
3. Do the Quha Zono mouse and the USB receiver have the same serial number on them? The mouse and the USB receiver are paired based on their serial number. Only devices with identical serial numbers communicate with each other.
4. Is the USB receiver connected to the computer and is the computer’s USB port working? If another USB device works on the USB port, it is likely that the USB port is ok.
5. USB receiver may be broken. For example, the USB connector may have gotten detached from the circuit board. In this case, the USB receiver needs to be repaired.
6. If these measures do not fix the problem, please contact Quha support.

Yes you may be able to use them. However, Windows XP, Vista, 7 or 8 are not anymore supported by Microsoft, and therefore we are not able to provide the official support for them on our software. We recommend updating to Windows 10 or 11.

Quha Zono 2 setup software requires Microsoft .NET framework to work. The latest .NET frameworks are not supporting Windows XP anymore, hence you need to download an older version, e.g. .NET 3.5 at http://www.microsoft.com/en-us/download/details.aspx?id=22. 

Gestures are supported by Quha Zono 2 and Quha Zono X only.

The Lithium-Ion battery in Quha Zono and Zono 2 are not user replaceable. Please contact your reseller or Quha certified service points.

If the device is disconnected from the charger, shows a solid green light and doesn’t respond to pressing the power button, it means that the device is somehow stuck. To continue it will be necessary to wait until the device battery runs empty and the device resets itself. Disconnect the device from the charger and when the indicator light turns off, wait one hour to guarantee that the battery is empty and the device is reset. At this point the device can be charged again and it will be operational.
