Warranty &Factory Service Instructions
Returning a Product for Service
mtk Peter Kron GmbH Medical Test Devices, Software & Services
If it is determined that you need to ship the unit back, it is highly recommended that you
pack the product in its original shipping carton and packing materials, provided that they are still useable. If
the original packaging is not available, select a sturdy corrugated carton large enough to hold whatever items
you are returning, and also to allow 4 to 6 inches of packing material on all sides of the items. Whether you
use the original packaging or an appropriate substitute, please follow these packing instructions:
1. Remove all hoses, cables, power cords and any other accessories from the instrument and, if possible.
Note: if you are using substitute packaging, it is essential that you seal the instrument in a clean, static
free plastic bag or in clean bubble wrap in order to prevent packing material from entering the product.
2. Pack only the accessories you are requested to return; place them in a separate bag.
3. If you are using substitute packaging, create a foundation of 4 to 6 inches of packing material (either
bubble wrap or packing "peanuts") at the bottom of the carton.
4. Insert the instrument and the accessory bag into the shipping carton.
5. If you are using substitute packaging, fill the 4 sides and the top of the carton with 4 to 6 inches of packing
material (either bubble wrap or packing "peanuts"). Ensure that the instrument and accessory bag are held
firmly in place by the packing material.
6. Please place paperwork such as the purchase order, contact info and reasons for return in the top of the
carton.
7. Close the carton and securely seal it with tape; since in most cases the carton will have been previously
used, it may be necessary to reinforce the original tape on the bottom of the carton.
8. Ship the product via whatever carrier (UPS, FedEx, etc.) is most convenient. However, please be aware
that, depending on where you are shipping from, standard UPS ground shipping could take as long as 7
business days. Unless other arrangements are made, mtk will return the repaired product to
you via UPS.
Additional Instructions for International Shipments
9. Shipping insurance is optional. Claims for damage to the product during shipping must be initiated by the
shipper.
Customers outside the United States must include a "pro-forma invoice" for customs purposes as part of their
shipping documents. It is imperative that the name of the product appears exactly as follows:
SmartArm Test Equipment
Or
SmartSat Test Equipment
The use of any other product name could add unnecessary delays when shipping internationally.

The SmartSat Pulse Oximetry Analyzer is the first test system available to test both the probe and pulse
oximeter independently. This method allows the user to diagnose problems to either the probe or pulse
oximeter. The SmartSat has two probe test modes and a SpO2 simulator mode with user programmable
Auto Sequences for automated testing.
The first probe test is the Probe Continuity Test. This tests the probe for opens, shorts, and intermittent
probe problems. The Probe Continuity Test provides an electrical integrity test of the probe.
The second probe test is the Probe Sensitivity Test. This tests the sensitivity of the RED and IR LEDS and
the ratio of the Red to IR sensitivity. This test is valuable for testing a probe during its functional life. The
user can then determine if the probe is within an acceptable sensitivity range.
The SpO2 Simulator tests the pulse oximeter through a complete range. The full featured SpO2 simulator
provides the following features: Oxygen Saturation; Pulse Rate; R-Curves for testing pulse oximeters and
user programmable Auto Sequences for automated testing.
In addition to these testing features, the SmartSat incorporates a high-resolution graphic display, an internal
battery, built in probe test ports and a compact, lightweight enclosure.
The Operation Manual is intended for end users of the SmartSat Pulse Oximetry Analyzer. It contains
installation and operation instructions, applications notes, performance limitations and routine performance
verification procedures. To achieve satisfactory results, it is imperative that the operator read this manual
thoroughly before attempting to use the SmartSat.

The values labeled "Typical" in the table below were obtained by averaging the readings obtained by
performing the SmartSat's Probe Sensitivity test on a large number of good pulse oximeter probes. The
values labeled "Typical Range" are values at which, when the "probe under test" measures outside this range,
it should be considered suspect. Since the pulse oximeter manufacturers have thus far declined to provide
absolute limits for these ranges, we can not positively state that probes that exceed these limits are "bad."
However, we can state that they deviate significantly from the "typical" probes of that make and model. In
general, when evaluating probes using the Probe Sensitivity test, if you obtain a reading outside the limits,
you should take into account other factors. For example, multiple readings (such as Red and Ratio) outside
the limits or an out-of-limit reading on a probe that is old or looks worn, is probably an indication of a probe
that may malfunction under certain clinical conditions.

A: Simply connect a Nellcor, BCI, Nonin or Ohmeda probe into the Nellcor or Ohmeda Probe Analyzer
ports on the side of the SmartSat. For other brands of probes, use the appropriate Probe Analyzer Cable
and connect it into the Ohmeda Probe Analyzer port. Then connect the probe to the Probe Analyzer
cable to test the probe.
Q: Why does the SmartSat test the probe and oximeter independently?
A: During the extensive market research when developing SmartSat, we found that over 96% of all
oximetry problems occur within the probe. SmartSat is a "True Test Standard" utilized by major pulse
oximetry manufacturers for electrically testing the functional accuracy of pulse oximeters. With both a
SpO2 simulator and Probe Analyzer in one test system, problems are correctly identified and can be
repaired. There is no guesswork involved.
Q: What types of probes can be tested?
A: All types of probes (except MRI probes) can be tested with SmartSat:
1. Adult size permanent probes
2. Adult size disposable probes
3. Neonate size permanent probes
4. Neonate size disposable probes
Q: How does the Probe Continuity Test work?
A: The Probe Continuity Test completely checks each probe for open, short, and intermittent failures. The
probe can be tested correctly throughout its useful life cycle.
Q: I am using the Probe Sensitivity Test and when I open the finger probe or hold it towards the light,
my readings are affected. Why does this happen?
A: When the probe is opened, it separates the LED's and the Photodiode paths. The farther the Photodiode is
from the LED's, the less red and infrared light reaches the Photodiode, which affects the readings.
Section 5. Frequently Asked Questions
5-1
mtk Peter Kron GmbH Medical Test Devices, Software & Services
A: SmartSat works with the following pulse oximeters; BCI, Criticare, Criticare SPOT, Datascope, Datex,
Hewlett-Packard, Masimo, Nellcor, Nihon Kohden, Nonin, Novametrix, Ohmeda and Sensormedics.
Q: How are the R-Curves obtained?
A: Our engineers obtained the information from and worked with each manufacturer to assure a "True Test
Standard" for testing pulse oximeters. We thank those manufacturers for their help. Because of our
relationships with these manufacturers through non-disclosures and supplier agreements, we are assured
future compatibility by these manufacturers using SmartSats for testing their pulse oximeters throughout
their organizations.

Remote control of the SmartSat‘ by a host computer is possible via an RS-232 serial port located on its right
panel. This RS-232 port, a 9-pin female D-shell, is configured as a "DCE," allowing direct connection to the
serial port on IBM-compatible computers. Therefore, to connect the SmartSat to an IBM-compatible PC, a
standard cable, rather than a null modem cable, should be used. (A CGA video monitor extension cable,
readily available in computer stores and mail-order catalogs, can be used. Alternatively, mtk
can supply the appropriate cable.)
The serial port on the host computer should be configured with the following communications parameters:
Baud Rate:1200 baud
Data Bits:8
Stop Bits:1
Parity: None
The SmartSat’s communication protocol is essentially an all-ASCII, all-uppercase format. (The only
exceptions are messages that contain waveform datapoints in binary code.) An ASCII format facilitates
using popular PC communications software such as Windows Terminal, ProComm or Crosstalk as a
“control console” to interact with the SmartSat. Before developing the remote control software for use in
your application, it is recommended that the programmer familiarize themselves with the communications
protocol using PC communications software.
To send remote control commands using the Windows 3.11 Terminal program:
• Select the -Communications option under the Settings pulldown menu and set the following:
Baud Rate:1200 baud
Data Bits:8
Stop Bits:1
Parity: None
• Then select the -Terminal Preferences option under the Settings pulldown menu and set the following:
Enable “Local Echo” under “Terminal Modes”
Enable “Outbound” under “CR->CR/LF”
Communication between the SmartSat and the host device consists of two categories:
1) Command messages sent by the host to the SmartSat
2) Response messages sent by the SmartSat to the host
The following pages describe the command messages and response messages in detail.
Please note that if the terminal is receiving repeated strings of “SRP” it is because the SmartSat RS-232 port
is set to “DataLog” not “Remote Control” This can be changed via the “Advanced” settings on the SmartSat.
Note: Brackets are for documentation only and are not part of the command format.
As shown above, host command messages consist of four (4) fields:
1. Preamble: [SS]
2. Command Field: a single uppercase letter (described below)
3. Data Field: 0 or more bytes (command dependent)
4. Termination Character: <cr> (i.e., hexadecimal “0d”, the ASCII carriage return control code)
5. Optional Termination Character: <lf> (i.e., hexadecimal “0f”, the ASCII line feed control code); Note use
this character to improve readability of commands and responses when controlling the SmartSat using PC
communications software.
A checksum is not used because it is awkward to generate and transmit checksums with an ASCII terminal.
Message integrity checking is achieved via a structured message format; limit tests for all transmitted data;
and command and data acknowledgment.
See the attached table for a list of commands and the associated data field contents.
Generic Command Message Format
Section 7. Remote Control, Version 0.3
7-2
mtk Peter Kron GmbH Medical Test Devices, Software & Services
As The SmartSat receives and parses the incoming command message, if it encounters an illegal command
syntax, it will generate a "SyntaxError" response.
[DataError]<cr><lf>
If the SmartSat encounters an illegal data value, it will generate a "DataError" response.
After receipt of a valid command and valid data, and after the SmartSat has successfully executed the
command, it will acknowledge that fact to the host by echoing the preamble and command field followed by
an "=" sign, the data field and the termination character.
