KLN 35A - needs an update

[steve]

I need to remove my KLN 35A but I can't figure out how - small hole in the
front - I assumed it was for an allen wrench - none of mine fit it - too
small for a tiny screwdriver - what's the secret to getting this thing out ?
The battery in the unit is going dead and needs to be replaced - figured I
could do this myself if I could remove the unit.
Also going to have to update the database now that the battery died - and I
don't have a laptop to do an upgrade (couldn't get to the back of it anyway
if I did have one) - and I can't even seem to find a place to get an
update - the phone # in the manual is no longer good.
Any help here ?
Thanks,
Steve

Bendix-King units do use an allen head. It's fairly tiny, and the screw is pretty far
back. The driver my avionics tech uses is about 9" long.

If you don't tell lies, you never have to remember what you said.

The KLN 35A has something that is in that hole only about 1.5 to 2" in
there, my small allen wrenches stop at that point - am wondering if maybe
this takes a metric allen wrench - I just can't see in this tiny hole to see
what is in there.

At least on my 94 there's an allen wrench required screw right in the
middle hole on the bottom of the unit. It's got one of those
screw-tab things - turn it one way a little tab comes down and locks
the unit in place, turn it the other and it retracts and will let the
unit slide out. I think you turn it to the right to get it to
retract, but it's been a while. Keep turning and the tab will slide
back along the length of a screw which runs the length of the unit.

My tech had a bear of a time getting it just right. Came out easy
though, getting in was the fun...
