The KT3 series is a popular line of smart displays that are used for managing settings. I am under the impression that it originates from Suzhou Kunteng Electronics Co., they have manuals and if you stumbled on this page looking for other models, you might want to visit them. Their server is very slow from time to time. Below are also cached versions, to save you from a waiting frustration.

There are three “Parameter Setting” chapters for 22 settings:

• “General Project Setting” (3)
• “P Parameter Setting” (5)
• “C Parameter Setting” (14)

Setting Parameters

Setting is done with:

• Arrow Up == UP
• On/Off == ENTER
• Arrow Down == DOWN

How “enter settings” work:

• Start with “General Project Setting”:
  • Press ENTER long to start. When On, within 5 sec press UP+DOWN for 2 sec
  • Within a minute: Use UP or DOWN to change values if needed, click ENTER to store and go to next value.
  • After entering last setting (third, Metric or Imperial):
    • Press ENTER for 2 sec to save and finish, or…
    • Press UP+DOWN for 2 sec to get into “P Parameter Setting”
• Continue with “P Parameter Setting”:
  • Within a minute: Use UP and DOWN to change values if needed, click ENTER to store and go to next value.
  • After entering last setting P5:
    • Press ENTER for 2 sec to save and finish, or…
    • Press UP+DOWN for 2 sec to get into “C Parameter Setting”
• Continue with “C Parameter Setting”:
  • Within a minute: Use UP and DOWN to change values if needed, click ENTER to store and go to next value.
  • After entering last setting C14 press ENTER for 2 sec to save and finish.

In short, turn on – ENTER, directly UP+DOWN 2s, ENTER through the three General values, after last value UP+DOWN 2s for P Settings, ENTER P1… P5, UP+DOWN 2s, ENTER through C Settings and ENTER 2s to save.

Values

Tip: Write your settings down somewhere, if something breaks and you need a new device, you really wants these settings back.

Here are my values with their meaning, you can paste and modify it in a spreadsheet for your convenience.
