GENERALS ervice manual ECG-9010/9020 Rev Service manual provides useful information to qualified Service personnel tounderstand, troubleshoot, Service , maintain and repair the ECG-9010K, ECG-9020K/P and ECG-9022K Electrocardiograph (referred to in this Service manualas the instrument , ECG-9010K or ECG-9020K which includes ECG-9020 Pand ECG-9022K).All replaceable parts or units of this instrument and its optional units are clearlylisted with exploded illustration to help you locate the parts System test, Adjustment and Setting section in this Service manual describesthe maintenance that should be performed by qualified Service personnel.

6 TheMaintenance section in the operator s manual describes the maintenance that canbe performed by the information in the operator s manual is primarily for the user. However, it isimportant for Service personnel to thoroughly read the operator s manual andservice manual before starting to troubleshoot, Service , maintain or repair thisinstrument. This is because Service personnel needs to understand the operation ofthe instrument in order to effectively use the information in the Service manual ECG-9010/9020 Rev BService PolicyNihon kohden Corporation s basic policy for technical Service is to replace faultyunits, printed circuit boards or parts. We do not support component-level repair ofboards and units outside the factory for the following reasons: A special facility is necessary to repair multi-layer boards because most of thecomponents on the board are SMD (surface mount devices) and most of thecircuits employ a gate array method.

7 To fulfill safety certification requirements, a special facility is necessary to verifysafety as medical equipment after the power unit is When ordering parts or accessories from your nearest nihon KohdenCorporation s distributor, please quote the NK code number and partname which is listed in this Service manual , and the name or modelof the unit in which the required part is located. This will help us topromptly attend to your needs.
