H = Headset
C = Cord, Adapter, PTT adapter or Extension Cord
M = Module
U = Utility intercom module
Model numbers are set up in series. The first two digits indicate the series i.e. H3341 is a headset in the 3300 series, C38-12 is a 3800 series cable.
The second two digits tell about the configuration of the headset. The pattern is as follows:
Hxx10 & Hxx20 = Mic shield microphone
Hxx30 = Boom microphone, over the head style
Hxx40 = Boom microphone, behind the head style
Hxx50 & Hxx60 = Listen only, no microphone
Hxx70 & Hxx80 = Cap attachable or lightweight model
Hxx90 = Single ear over the head style
You'll note that the fourth number sometimes changes. That just means the product is a variant on the series. In other words there could be two headsets that are very similar and vary on some feature and so have the same basic number but one digit different i.e. H3340 and H3341. The difference is that the H3340 has two speakers and the H3341 has only one.
Additionally, some products only have part numbers and you will need to check the compatibility table or with your two way dealer to see what series the part you have belongs to.
BTH = Behind the head style headset
ULW = Ultra Light Weight, Single Ear, Over the head style
