I too see the same problem with LEICA MDB format.
With TPS data
I get different message.
! Warning ! Topcon TPS with possible non-standard message starting
! Warning ! Topcon TPS corrupted data or mis-partsing by teqc
The TOPCON is from a TPSG3_A1 with firmware 3.2
I only have receivers with firmware 3.2 so I cannot see if this is a
new or earlier error message.
