details). The current sampling frequency is shown on
the status indicators 6.
4HR MODE key
This key allows the selection of the recording resolu-
tion (16-bit or high-resolution 24-bit). See 5.1, “For-
matting a tape” for details.
The appropriate indicator 6 will light if the HR

6Status in dicators
The status indicators show the current status of vari-

list of their full meanings, together with the pages on
which the functions are more fully described:
7Tap e c ou nte r
The tape counter gives the current tape time in hours,
minutes, seconds and frames.
It is a l so used to displa y m enus, sub-menu s and th e

8PB CONDI TION ind icator
There is one more indicator: PB CO NDITI ON, which
lights if there are many errors when reading or
recording the tape. It also flashes when the block
error rate is being checked (11.1.2, “Checking error

If this lights frequently, the block error rate can be
checked and the heads cleaned (11.1, “Head and
transport cleaning”).
