Maintenance

Replacing the battery periodically ensures battery operation

when needed. A periodic battery check is also recommended.

The interval for this check is at the user's discretion.

Depending on how the monitor is used, the user may wish to

perform a battery check as often as every 6 months. This check

should also include inspecting the battery's physical condition.

Any batteries showing leakage or corrosion should be replaced.

Qualified service personnel should check the battery following

instructions given in the N-200 service manual. Regardless of

periodic test results, Nellcor recommends battery replacement

every 2 years. Replacement batteries can be purchased through

Nellcor's Technical Services Department or your local Nellcor

representative.

DETERMINING SOFTWARE VERSION

To determine the N-200 software version, press the HIGH SAT

and AUDIO ALARM OFF buttons. A two-digit version number

appears in the PULSE RATE display. For example, version 2.7

appears as 27. It may be necessary to turn the control knob

until 0 appears in OXYGEN SATURATION display. To

determine the powerbase software version, press the HIGH

SAT and AUDIO ALARM OFF buttons again, and turn the

control knob to the left until Pb appears in the OXYGEN

SATURATION display; the version number appears in the

PULSE RATE display.

For technical information or to order parts or a service manual,

contact Nellcor's Technical Services Department or your local

Nellcor representative. The service manual includes circuit

diagrams and a spare parts list, which may be required by
