Yaesu FT-991 Operating Manual page 2

The FT-991 is a leading-edge transceiver with a number of new and exciting features, some of which may be unfamiliar
to you. In order to gain the most enjoyment and operating efficiency from your FT-991 , we recommend that you read
this manual in its entirety, and keep it handy for reference as you explore the many capabilities of your new transceiver.
Before using your FT-991 , be sure to read and follow the instructions in the "Before You Begin" section of this manual.
FT-991 utilizes a TFT liquid-crystal display.
• Although TFT liquid-crystal displays are made using very precise technology, they are prone to develop
dead pixels (dark dot) or pixels that are always on (bright dot). Please understand that such phenomena
do not constitute product defects or malfunctions. Rather, this phenomena occurs due to limitations in the
manufacturing technology with respect to TFT liquid-crystal displays.
• Depending on the viewing angle, unevenness in color or brightness may occur. Please note that any uneven-
ness observed is inherent to the construction of TFT liquid crystal displays and therefore does not constitute
a product defect or malfunction.
• If your TFT liquid-crystal display becomes dirty, please use a dry soft cloth or tissue to wipe the display
clean. Use of glass cleaner, household cleaners, organic solvents, alcohol, abrasives, and/or like substance
may damage the TFT liquid-crystal display.
