Although 3 kinds of tapes are set forth for the playback ievel adjustment, the use of one tape suffices for adjustment. Here is meant no necessity
for the use of all these 3 kinds of tapes. Other than the abovementioned tapes, when a test tape equal in magnetic flux and frequency ts
available, the adjustment is feasible with this test tape by making the playback output suited to the specified output level of this tape in
|
agreement with the adjustment method.
% For your safety, remove the MECHANISM Assy with FRONT PANEL & PCB when you adjust tape speed.
