  • When doing a Yaesu Transceiver firmware update, you should disconnect CatTouch and any other connected device from your transceiver

  • There is no reset button or procedure on CatTouch. Updating firmware restores all factory defaults & you can do this as many times as you like

  • During development of CatTouch, several Yaesu CAT idiosyncrasies have been observed:
    FTdx10, FTdx101D: Clock does not update if transceiver screen saver is on - no fix
    FTdx101D/FTdx101MP: Many CAT devices caused transceiver to reboot - update transceiver firmware fixed problem
    FT-991A: Clock does not change if clock settings screen open on transceiver - no fix
    FT-991A: In C4FM mode, CAT command responces for width, contour & notch are all incorrect - no fix
    FT-991A: LCUT slope keeps changing in SSB mode - no fix

  • If you find the stylus does not work properly or erratically, reload the firmware
    Common symptoms include screen buttons / tabs not working (not the JPG TAB though, it is always slow to react)
    This will reset everything & force the calibrate screen to be displayed

  • When calibrating touch screen, it is important you touch as close as practical to the arrow point
    Please use the included stylus

  • A firmware update overrides everything & you will need to reapply any Zulu/UTC, 232C rate or voltage offset

  • You do not have to upload every sequential firmware version - you can skip firmware versions at any time

  • To update the firmware, download the latest version from the CatTouch product page
