Cleaning
Occasional cleaning with a soft cloth is recommended. Do not use detergents or
chemicals. Do not submerge the QRAE II or place it under running water. If necessary,
you can use a damp cloth (water only). For the diffusion model, it is a good idea to install
the Calibration Adapter before cleaning the QRAE II’s housing, to keep dirt, dust, or
moisture away from the sensor openings and to keep the filter clean.
Visually inspect the contacts at the base of the QRAE II, on the battery, and on the
Charging cradle to make sure they are clean. If they are not, wipe them with a soft, dry
cloth. Never use solvents or cleaners.
