Because keyword searches can sometimes lead to outdated versions, use this checklist to ensure you have the genuine R4.0 New PDF:

Official Hytera Website: Go to the "Support > Download Center" section. Filter by "Mobile Terminal > MT680."
Filename check: The genuine file is typically named Hytera_MT680_User_Manual_V4.0.0_EN.pdf.
Page count: The R4.0 edition should have 142 pages (the R3.0 had 128).
Watermark: Look for a faint "Hytera Communications" footer on every page.

Warning: Avoid third-party document hosting sites that still serve the R3.0 manual as "new." Always verify the revision number on the copyright page (bottom right).
