Maintenance
Serviceability: Except for replacing the oxygen sensor, there are no parts inside the transmitter for the operator to service.
Only trained personnel with the authorization of their supervisor should conduct maintenance.
Oxygen Sensor: DO NOT open the sensor. The sensor contains a corrosive liquid electrolyte that could be harmful if touched
or ingested, refer to the Material Safety Data Sheet contained in the Owner’s Manual appendix. Avoid contact with any liquid or
crystal type powder in or around the sensor or sensor housing, as either could be a form of electrolyte. Leaking sensors should
be disposed of in accordance with local regulations.
Troubleshooting: Consult the guidelines in Section 8 for advice on the common operating errors before concluding that your
transmitter is faulty. Do not attempt to service the transmitter beyond those means described in this Owner’s Manual.
Do not attempt to make repairs by yourself as this will void the warranty as per Section 10 and may result in electrical shock,
injury or damage. All other servicing should be referred to qualified service personnel.
Cleaning: The transmitter should be cleaned only as recommended by the manufacturer. Wipe off dust and dirt from the
outside of the unit with a soft damp cloth then dry immediately. Do not use solvents or chemicals.
Nonuse Periods: If the transmitter is equipped with a range switch advance the switch to the OFF position and disconnect the
power when the transmitter is left unused for a long period of time.
