Troubleshooting

LCD needs calibration
o When the LCD Calibration tab is selected, crosshairs will
appear onscreen and users should select these one by one to
calibrate the touchscreen. If the screen becomes uncalibrated
for whatever reason, and the appropriate menu cannot be
selected onscreen, users should use the IS16's onboard
controls to navigate the GUI and bring up the LCD Calibration
function.
Firmware updates and version check
o Please always delete your old firmware from the SD card
and check the firmware version before updating the unit.
Firmware updates are accomplished by inserting an SD Card
and selecting the appropriate Firmware update option in Setup
menu of the GUI.
I cannot see the screen properly
o You can adjust the brightness of LCD.
o Move the unit out of direct sunlight.
The power won't turn on
o Is the power supply connected to the unit, and the AC-end to
an appropriate source?
o Is the optional expansion card installed properly?
o Have you performed a system restore?
o If the power still does not turn on, contact your nearest Phonic
dealer for service.
After a firmware update, my firmware version is left unchanged
o Don't forget to reinitialize your system.
The system restore doesn't work
o Did you format your SD card as a FAT file system?
o After an initial restore failure, the entire restore must be
performed from the beginning.
There is no output signal
o Is the optional expansion card installed properly?
o Is the "On" key indicator of the Main channel lit?
o Is an output assigned to the output channel?
o Is the level of that output too low?
30
Sound is too soft
o Is the GAIN of the mic preamplifier or external preamplifier set
to an adequate level?
o Is the fader of the input channel raised?
o Please check the EQ settings as you may be excessively cutting
signals.
o Check the Dynamics setting for the same reason as above.
o Enter the Meter function to check both input and output levels
simultaneously.
Sound is distorted
o Is the Master Clock setting correct?
o Is the GAIN of the mic preamplifier or external preamplifier set
to an appropriate level?
o Could the fader of the input and output channels be raised too
high?
o Could the Main fader be raised too high?
o Could the EQ/DYN gain be set to an extremely high setting?
o Have you inadvertently applied a digital effect or reverb to any
of the channels?
Digital glitches
o Is the Master Clock set correctly?

Can't save to external SD card
o Is the SD card write protected?
o Ensure your card is either an SD or SDHC card.
o Does the SD card have enough free space to save the data?
o Ensure the card is formatted in FAT32 or FAT16? NTFS is not
supported.
o For best results, try a SD-HC card between 2GB and 4GB in size.
Can't perform a system restore
o Is the SD card formatted as a FAT file system?
o Were both steps in the restore process followed precisely?
o Did you reinitialize the unit after the restore was completed?
