Batboard

According to the manual, the UHF XTS5000 with a NNTN4717 vocon requires the C03 display module.
Not having one, I used a C02 from an 800 XTS with the NNTN4717 vocon and it appears to be working 100%

Normally I just shrug my shoulders and say "that's nice" but it's bugging me

Anyone know what the difference is or why the C03 is spec'd for the UHF XTS?

Full part number is 7285726C0x

Thanks.

Never had issues with the other part number displays or even vocon boards. They all seem to work as you described.

Just ordered some more displays last week and Motorola have changed the part number AGAIN!

New part #: 72009264002

It has to do with the shielding on the display itself. I fiddled with a 800Mhz display on a vhf radio, with RF getting into it, it was very quirky. IIRC the C04 is a universal display as of now for all bands.
