FS Functions
58 FS-4 HD and FS-4Pro HD Portable DTE Recorders
• USE EXT FS-4
Use this option when longer recording times are
needed.
USE EXT FS-4
permits the connecting of two
FS-4 HDs together to provide more disk storage for
longer recording. One unit acts as the master with the
other as a slave: the master records to itself until full
and then continues recording on the slave unit.
Identifying Master/Slave Volumes During Record/Playback
When two FS-4 HDs are in combined via USE EXT FS-4 and in
either Record or Playback mode, the volume on the Home screen will
display 1-xxx when the master unit is recording or playing back and 2-
xx if it is the slave.
