Informazioni
Three types of Odyssey models have been produced: I) 2800,
2) 2810-2815 and 3) 2820-2823. The model and serial number
are located at the rear or bottom of the Odyssey chassis.
Except for 2800, a typical number might read: 2813-0490. For
model 2800, the first two digits of the serial number denote
the model, such as: 28490. Listed below are the board
identification numbers for each model; they will be
referenced in the service manual by model number for easy
identification.

Informazioni
This service manual is divided into three major sections: A)
Circuit Descriptions, B) Trim Procedures, and C) Board Test
Points. The circuit descriptions should be consulted when a
problem is suspected in a particular area of the instrument.
The trim procedures should be used to verify calibrations or
when a component has been changed. The board test points are
a quick reference to verify circuits with suspected problems
and should be checked whenever a problem has been identified.
