KCH-21R Remote Handheld - Dip Switch

[Vern]

Just acquired a used KCH-21R handheld remote head to use in my vehicle to replace the KCH-20R.
There's no documentation with the -21R and the online manuals don't mention the single DIP Switch under rear flap next to the RJ-45.
Currently that switch is "ON" and it's past life the -21R was connected to a single deck (NX-5800).

I'm planning to connect it to a dual-deck setup (5700/5800). Should I leave the -21R's switch to "ON" or is this switch used for some other function?

The remote head configuration manual that I have doesn't address the -21R models at all, only the -19 and -20 versions.

Thanks.

Make sure you do a firmware update when you put it together, or add another deck.
This puts all the inner works in order and you wont get mis-match, and head error
after you dump in the new file with the 21 head turned on in Product Info.

I had already updated the firmware in the -21 head to match the dual decks, so when I swapped out the -20 for the -21 and loaded the two codeplugs for each deck the unit booted up first time... almost like I knew what I was doing. Thanks for your valuable assistance.
