after background radiation drops below the preset threshold.
When the De threshold is exceeded it doesn’t necessarily mean
that there is a radiation source nearby. Moreover, the red De
alarm will not stop even if the current background radiation level
returns to its normal state. This usually means that the User has
been in the increased radiation background field for too long and
the risk of damaging effects to personal health is elevated. Please
consult health specialists in such circumstances or in case of any
uncertainty.
The red De alarm can be reset only by connecting PM1904 to an
iPhone
®
and using the User Software.
IMPORTANT!
To set up suitable values for thresholds and/or to get instructions
for dealing with any given value of DER/DE the user should consult
authorized licensed specialists. The User assumes full responsibility
for compliance with applicable laws, regulations, and standards in
connection with the use of the device. Additionally, the User bears all
the risks in interpreting the device output and/or making decisions
based on the device operation(s) or reading(s).
To set new thresholds, and/or reset current De value to zero,
connect PM1904 to an iPhone
