Dirt can gang up on your set fast, so
keep your set clean and cool.
If you' re using the new type air filter
assembly NSN 4130-00±879-2280, the
frame holder is part of the filter.
You'll have no need for the metal
frame used to secure the old type filter.
While you're keeping that set cool,
steer clear of setting those channel
frequencies
too
close.
Setting
'em
closer than 50 channels apart will
damage the 2A1AR1 RF aMplifier in
your R-1329 radio receiver.
