AN/VDR-2 Radiac Set . . .
If the window becomes dirty, clean
it carefully with a dry cotton swab.
NBC NCOs, remember the probe and
radiac meter have been calibrated to-
gether. If either malfunctions, don’t try
to fix the problem by swapping com-
ponents with another AN/VDR-2. That
won’t work. Turn in the entire radiac
set to TMDE for repair.
Keep the beta shield closed as much
as possible to protect the delicate probe
window. When you scan, be careful
not to brush the probe against anything.
Even a pin prick in the window can
ruin the probe.

If you don’t pack the AN/VDR-2
right, you damage the probe cord or
the batteries. Packing goes like this:

f your AN/VDR-2 radiac set is to
be sensitive to radiation threats, it needs
a bit of sensitive PM from you.
Before you go to the field, eyeball
the cable from the probe to the radiac
meter for fraying, especially at the con-
nectors. If the cable’s in bad shape, the
AN/VDR-2 will flunk the self-test.
TMDE needs to check out or replace
the cable.
Make sure the clamp will hold the
beta shield open. If it doesn’t, you’ll
have trouble scanning. TMDE can re-
place the clamp with an improved
clamp that solves the problem.
