BS8 Time Master: Top display, blue

Sychronizes time of pre-programmed BSF-7/8

Doubles as clear station on event day (programmable)

Does not 'replace' a BSM7/8 USB Master, see below

The drift of the internal clock in a BSF8 is minimal

But recommended to sync every couple months

Control setter can easily use this device right before an event

One can also sync using BSM7 plugged into a computer

But after all, you may program the units only once

BS8 is portable and for the periodic time sync only

Can also use as a clear, change modes using Service/Off card
