How do I replace the Li-ion battery in a Kenwood TM-741A?
we've got device-specific tags.
Now, I'd like to think it'd be a good idea to have a guideline on whether to tag with the individual device type.
I'd go with "no", because that means an endless flood of tags which will mostly have one question tagged with it.
But: there's arguments for "yes": If you have experience with a Skynet T-1000 multi-band transceiver with Band-Reshaping, you might want to watch questions tagged t-1000. That way, you'd get an email when someone tags their question. On the other hand, subscribing (as far as I know) only works for existing tags, so you'd need to ask a "dummy" question first if you're the first to want to have a device.
