Test AN/UDR-13 for Beeping
Some AN/UDR-13 radiacmeters have a software
problem that causes them to beep–and you
can’t turn off the beeping. That could be
disastrous in a combat situation where the
beeping could alert the enemy. So it’s critical
you CBRN specialists check to see if any of your
AN/UDR-13s are beepers, especially if their serial
numbers range from 6000C to 33000C.
Turn them on and let them operate away
from a radiation source for at least 20 minutes.
If one beeps, mark it so you know not to use it in
a situation requiring silence. CECOM is working
on a fix, which PS will let you know about.
It’s OK to use the beepers in non-combat
situations.
They
still
accurately
measure
radiation.

Quick Fix for Viewing PS Online
Has your computer been upgraded from Adobe Reader 9® to Adobe Reader X® recently?
Then you’ve probably noticed a problem when trying to open a copy of
PS Magazine
online.
There is an incompatibility problem between Adobe Reader X® and Internet Explorer 7®
(IE 7®) that causes a failure when trying to open large PDF files like
PS Magazine
. Adobe is
looking into the problem.
Until a solution is found, there are two work-arounds to try. First, use the Mozilla Firefox®
Internet browser to access
PS Magazine
. Firefox® is a bit slower than IE 7®, so be patient until
the file opens.
Second, you can use IE 7® to download PS issues directly to your hard drive. Just right
mouse click on the cover for the issue you want, choose Save Target As and select where you’d
like to save the issue on your hard drive. Then open the issue using Adobe Reader X®.
Starting with PS 704 (Jul 11), the red box links (Click here for a copy of this article to save or
email) at the bottom of each article were changed to hotlinks. Even if you’ve downloaded the
issue to your hard drive, you can still click on the link to open that individual article in IE 7®.
The red box links in issues prior to PS 704 will not work if you’ve downloaded the issue to
your hard drive. They were designed to open files on the
PS
server and will only work when
viewing the issue in IE 7® or Firefox®.

from the DATE CALBR listed on the radiacmeter. This change applies only to the -PDR-77s used
