Troubleshooting

The power is not switched off.
Was the [POWER] button pressed after too long of a pause?
The power is not switched off unless the [POWER] button is pressed within 5 seconds after the "Press POWER Again !" message appears.
No picture is output to the projector.
Is the [VIDEO OUT] dial centered?
A fade is applied to output if the dial is turned either clockwise or counterclockwise. When performing output, adjust the dial to center. The
indicator above the dial lights up when the dial is at center. The indicator flashes when the dial has been turned either clockwise or
counterclockwise.
No microphone audio is output, even when the faders are raised.
Have the [GAIN] dials been turned to appropriate positions?
When input sensitivity has been lowered, no audio is output even when the faders are raised.
Is the connected microphone a condenser mic?
When you're connecting a condenser microphone or other device that requires phantom power, set the [PHANTOM +48V] switch to ON.
Input from an external audio mixer is distorted.
Does the device have a high nominal output level?
The VR-5 has a nominal input level of -10 dBu. When you are connecting a equipment that has a high output level, such as +4 dBu, connect it via
an attenuator.
Transition effects are not applied.
Is the length of time for transition effects (TRANSITION TIME) set at zero?
When the time is set at zero, no transition effects are applied even when [MIX] or [WIPE] is selected.
A logo cannot be input from a computer.
Is the RGB output from the computer at a resolution supported by the VR-5?
RGB signals at a resolution that the VR-5 does not support cannot be input correctly. For supported resolutions, check "Main Specifications" (p. 65).
Video from the computer is not smooth.
This does not indicate an equipment malfunction. When quickly moving image is input from computer, flicker or other image corruption may
occur. This is called "tearing".
Compositing a logo is not possible.
Is the extraction color set correctly? Alternatively, was the [KEY LEVEL] dial turned in the wrong direction?
When the default settings are in effect, black is extracted to luminance keying and blue is extracted for chroma keying. If the background is a
different color, then correct extraction is not possible. Correct extraction is also impossible when the [KEY LEVEL] dial has been turned in the
wrong direction.
Audio is not linked to video transitions.
Is the channel of the audio you want to link not selected as the target for linking?
On channels that are not set as the target, no automatic switching of output and muting takes place when the video is switched. Use the menus
to make these the target of linking (p. 64).
Picture-in-Picture compositing is not possible.
Is the [MODE] button in the video effects section dark?
When this button is illuminated, the compositing mode is set to SPLIT.
Recording and playback using a commercially available SD card are not possible.
Operation has been tested for many common commercially available SD cards, but operation with all SD cards is not assured. Depending on the
manufacturer and type of the SD card, correct recording and playback may not be possible. Try replacing with a different SD card.
Also, only cards of class 4 or higher can be used for recording or playback on the VR-5. Be sure to use cards of class 4 or higher.
SDXC cards cannot be used.
The VR-5 is compatible with SD cards and SDHC (High Capacity) cards, but does not support SDXC (eXtended Capacity) cards. Use an SD card or
SDHC card.
Flicker occurs on a flat-screen monitor.
Flicker can occur, depending on the displayed picture, but this is not a malfunction.
Recording/playback using a commercially available SD card is not possible.
When an SD card is in the write-protected (LOCK) state, data on the SD card cannot be recorded, played back, or manipulated by FILE UTILITY or
the like. When using an SD card on the VR-5, first clear the write protection (LOCK).
