Service Manual

3.1 General Service Information

The Teledyne Model MX300-I Portable Oxygen Monitor is designed to be robust yet compact in size. In order to achieve maximum reliability in a microprocessor-based instrument, a single PC board is used which relies exclusively on surface mount technology. Without access to specialized probes and test equipment, troubleshooting and repair of circuit board components are not feasible. A factory replacement of the entire PC board is more cost effective than a field repair of an individual component

With the exception of replacing the sensor or batteries there are no user-serviceable components inside the unit. There are no potentiometers or other adjustments to be made within this instrument. If a problem arises with either of these models that cannot be corrected by recalibration, changing the batteries or replacing the sensor as described in the users manuals, contact your locale Representative or Teledyne for assistance. When returning the unit to the factory for repair or replacement. See Section 3.11 for instructions on obtaining a Return Merchandise Authorization (RMA) number before sending a unit back to Teledyne for repair.

3.2 Overall Maintenance

The MX300-I requires very little maintenance, other than calibration, checking and changing the batteries and sensor, and cleaning the plastic housing. Occasional cleaning of the plastic surface can be done with isopropyl alcohol. Should any part of the instrument malfunction or fail to perform, the unit should be removed from service. There are no user-serviceable components within the instrument.

3.3 Battery Maintenance

DO: Test batteries regularly. (replace immediately when all 5 bars are missing).

DO: Always use alkaline batteries.
