HMN 3013A DTMF Tone Duration

How can I change the tone duration in this mike ? At present it is too short to access IRLP nodes.

The manual says to put JU-3 in position "A" to defeat the tone timing. Tone will last as long as the button is pushed. JU-3 is near the 3.58 mhz crystal.

OK, I give up !!!
Where do they hide JU-3 in this mike ??
I took it apart and I don't see it.

I found it, had to disembowel the mike entirely. They sure don't want you
changing it too often.
