Display modes of the digital hours meter
The digital hours meter has the following nine modes.
H01:OPERATION mode

H03:TAPE RUNNING mode
Displays the total number of hours the unit has been in fast forward, rewind, playback, or search (except for stop and still) mode in units of 1 hour.
H04:THREADING mode
Displays the total number of times the tape has been threaded/unthreaded.
H06:REEL SHIFT mode
Displays the total number of times that the reel has been shifted according to the size of the cassette (L cassette or S cassette) in use.
H12:DRUM RUNNING mode (resettable) Same as H02 except that the count is resettable.
By resetting the cumulative drum running time after changing the rotating head drum, this count can be used as a guide in determining when to replace the drum.

This count can be used as a guide in determining when to replace such components as fixed heads and pinch rollers.
