Care
Keep the alarm dry; if it gets wet, wipe it
dry immediately. Use and store the alarm
only in normal temperature environments.
Handle the alarm carefully; do not
drop it. Keep the alarm away from dust
and dirt, and wipe it with a damp cloth
occasionally to keep it looking new.
Modifying or tampering with the alarm's
internal components can cause a
malfunction and may invalidate its
warranty.
