500 Mk IV User Handbook
34
8: Do's and Don’ts
……. Do's
DO...Press FSA and FSB GENTLY !
DO...Change or charge batteries when Low Battery appears.
DO...When changing batteries, replace BOTH cells.
DO...Use the correct mouthpiece for this instrument.
DO...Use a clean, new mouthpiece for each COMPLETE breath test.
DO...Ensure the subject blows into the lipped end of the mouthpiece.
DO...Read this handbook carefully, and comply with its contents.
DO...Use a DRY mouthpiece for calibration checking.
….... Don’ts
DO NOT...Test the subject if you think he may have drunk or taken
ANYTHING by mouth in the last 20 minutes
DO NOT...Test the subject if he has smoked in the last 2 minutes.
DO NOT...Let the subject hyperventilate before supplying breath.
This cools the mouth and upper airways, so that alcohol is lost
[by condensation] from the breath on expiration, and so produces
a falsely low reading of the body alcohol loading. If necessary,
wait a minute or so before proceeding to take the breath sample,
after any such action by the subject.
DO NOT...Store the 500 in extremes of temperature, hot or cold.
DO NOT...Subject the 500 to violent shock. Treat it with respect!
DO NOT...Clean the case with chemical or abrasive products.
DO NOT...Allow the sampling port to become blocked.
DO NOT...Block or restrict the end of the mouthpiece while the
subject is blowing. This can seriously damage the instrument.
DO NOT...Re-use mouthpieces, for hygiene and accuracy.
DO NOT...Open the case: this will invalidate the warranty/service.
DO NOT...Deviate from the instructions in this handbook.
