English Replacing the rear cover
The vent membrane allows the CPRmeter to adapt to minute air pressure
changes while protecting it from fluid entry.
If the vent membrane in the center of the yellow rear cover is soiled,
contaminated, scratched or damaged, the rear cover must be replaced. Do
not attempt to clean the vent membrane.
WARNING: A soiled or damaged vent membrane may lead to inaccurate
feedback or fluid entry into the CPRmeter. If there are signs of fluid entry,
remove the CPRmeter from service and contact your Laerdal representative
for advice.
If the rear cover is damaged or does not fit flush with the CPRmeter housing,
or the rear cover screws have sharp edges or the washers under each of the
rear cover screws are missing, the rear cover must be replaced. See Chapter
8, Accessory, Consumables and Spare Parts.
1. Unscrew the rear cover using a flathead screwdriver (not supplied) or a
coin, and lift out the cover.
2. Remove the replacement rear cover from its packaging and check to be
sure it is not damaged.
3. Position the rear cover on the CPRmeter. Thread the screws through the
washers and into the cover, and tighten the screws.
