The instrument detected residual mouth . alcohol in the subject's breath sample.

The instrument completes the mode sequence, prints "INVALID

SAMPLE . XXX" in place of

"SUBJECT TEST

.iii"

and prints

"INVALID SAMPLE MOUTH

ALCOHOL" at end of the test sequence and prepares itself to begin another test.

Since normal body processes eliminate residual mouth alcohol within approximately

15 minutes, observe the subject for at least 15 minutes before beginning another breath-analysis.

During the observation time, the subject may not smoke, eat, drink, or introduce any substance into his mouth.

Furthermore, if the Subject regurgitates, note the time and delay beginning a breath analysis for at least 15 minutes.

High level radio. frequency interference is present.

The instrument halts the test, prints "INVALID TEST";

"INHIBITED RFI" and prepares to start another test.

If the instrument -isset in "DVM

TEST" when -radio frequency interference activates the RFI detector, returns to the' instrument

"NOT READY" followed by the diagnostic checks.

Locate the RFI source and either remove the source from the instrument's operational environment or instrument to move a environment free fromRFI.
