MAINTENANCE & CLEANING
When handling your PSAP, please be sure to hold it close to a surface (preferably soft surface) to
avoid damage if you drop it. Use a soft, dry cloth to clean the PSAP. Do not use water, alcohol swabs
or other cleaning solvents as they will break down or damage your PSAP. When your PSAP is not in
use, keep your PSAP away from heat and moisture and store in a dry cool place.
