Receiving Early Response Tone When Trying to Access Programing

When attampting to program an ETP-100, ETP-100, ETP-400 or ETP-500 series device I receive 1 confirmation beep after the first * is entered.

This is a side affect of having two way conversation enabled  on an inbound call (previously programming *78* into the device).
After the response tone enter *4**, and you should receive the single confirmation tone.

Proceed with programming as normal
