hi guys,

my repeater power supply got busted, the fuse, busted. replace it with the spare
but still it wont turn ON. install a backup power supply plug it on the rear
battery back up socket, it works. question, if i remove the built-in power
supply, for purpose of repair, how can i power it up ...

so that's a software/firmware upgrade only, the HKLN4456A, am i right? thanks.

we just purchased a Xir 8200 mototrbo repeater and i think is not DMM capable. wanted to ask if DMM option is just a firmware upgrade or also includes some hardware upgrade. thanks.
