Introduction
The IDEXX SNAPshot DSR Reader provides an easy-to-use method of reading and recording SNAP test results. With its touch-screen interface, the SNAPshot DSR Reader offers easy data entry and navigation. Its specialized technology provides quick, accurate test results. Just insert the activated device and read the test results.

The SNAPshot DSR Reader offers two test modes:
Full Read—Lets you record the test lot ID, tech ID and sample ID. Provides on- screen and printed test results. The Full Read mode is required in the United States for National Conference on Interstate Milk Shipments (NCIMS) testing.
Quick Read—Provides on-screen and printed test results. In the United States, the Quick Read mode does not meet NCIMS testing guidelines.
IMPORTANT: A printer is required for NCIMS testing. The SNAPshot DSR Reader printer is available separately from IDEXX. Call 1-800-321-0207 for additional information or technical service.

Setting up your SNAPshot DSR Reader is easy and takes only a few minutes. A PS/2 keyboard can be connected to the SNAPshot DSR Reader via the PS/2 port .

Use the keyboard’s Tab and Enter keys for navigation and the alphanumeric keys to enter lot, sample, and tech IDs.

To set up the SNAPshot DSR Reader

1. Position the reader on a flat surface in a well-ventilated area out of direct sunlight. The SNAPshot DSR Reader should be used in a controlled environmental temperature of 7–30°C (45–86°F, relative humidity: 10%–80% non-condensing). See the SNAP kit insert for specific assay temperature requirements.

2. If you are using a printer, plug the printer cable into the printer and then into the COM 1 port on the back of the SNAPshot DSR Reader.
   Note: A printer is required for NCIMS testing.
   Note: If you are using a printer from an existing SNAPshot Reader or a printer that was not purchased from IDEXX, refer to the “Settings” section of this manual for instructions.

3. Plug the power supply into the power port on the rear of the SNAPshot DSR Reader (see figure 2). Plug one end of the line cord into the power supply and the other into an AC-grounded outlet.

SNAPshot DSR Performance Check Set
SNAPshot DSR Performance Check Sets are available for both 2-spot mode (Beta- Lactam and Other) and 3-spot mode. Each SNAPshot DSR Performance Check Set consists of two SNAP devices with standardized printed spots in blue plastic bases. One device produces the negative ratio(s) and the other the positive ratio(s). Read the Check Set devices as you would any other SNAP device.
We recommend that the Check Set devices be used daily to verify the performance of your SNAPshot DSR Reader. Be sure to store the Check Set devices out of direct sunlight.
Note: The Check Set devices are not positive and negative controls and should not be used as positive and negative controls. If the Check Set device ratios are not within the range indicated on the Check Set label, see “SNAPshot DSR Reader Performance Check Set is Out of Range” in the “Troubleshooting and Technical Service” section. Verify that the Check Set is within the expiration date.
