• Make sure the Fish Finder source is set to the internal sounder of the
TZtouch2 MFD that you are updating. It should
not be set to a black
box sounder, such as a DFF1-UHD, DFF3, or to another TZtouch2
display in the network.
• The internal sounder menu settings are
not saved when you save
“User Settings” in the file menu. Record any customer sounder
settings to re-install them after the software update is complete. We
recommend taking pictures of the sounder menu.
• Scroll down to the bottom of the sounder menu and select “Set
Hardware To Factory Default”. Then select OK to reset the sounder.
• Turn the MFD off and back on again to fully initiate the sounder
menu reset.
Although not a requirement, it is a good practice to fully reset the machine
via the Service Man menu (or power up reset) after the update process has
been completed. Please see “TZT2 Factory Reset Procedures” or the
instructional video (TZTL v6.21 Software Update Video) which explains this
process.
