with the cobured markings identifying the terminals in your mains plug,
please proceed as follows:

connected to the terminal in the plug which is coloured green, or marked
with the safety earth symbol or the letter E'. The wire which is colour-coded
blue must be connected to the terminal cobured black or marked 'N'. The
wire which is colour-coded brown must be connected to the terminal
cobured red or marked 'L'.

inlet to the Delta 100 uses a standard lEC chassis mounting plug. The lEC
line socket on your mains lead, and the lEC plug on the Delta 100 are a
tight fit. Before using the unit, please ensure that the mains lead is pushed
firmly home. Under no circumstances should the cover be removed unless
the mains supply has been disconnected at the wall socket.

the right hand meter the 10kHz tone. For a flat frequency response these
levels must be equal. Because it is impractical to read levels of -20dB

accurately on the normal meter scales, a precise 20dB of gain is applied to
the meter circuits in the calibration mode. In addition an offset is applied to
the meter circuit in this mode so that the level change represented by each
meter segment around the OdB martt is reduced to approximately 0.5dB.
Using the BIAS and CALIBRATE controls it is then easy to match the replay
levels of the two tones to within 0.25dB. This will ensure an overall
record/replay response flat to well within +/- ldB over the range 40Hz to
15kHz for any tape close to the lEC standard.

CHECK LIST

check the following before suspecting a fault;

If you have any difficulty operating your cassette deck,
