Problem:
A GT-1C7W is being programmed by handshake. The station powers on, but the talk button is not available to press during handshake programming.
Cause:
The station is powered on, but there is no R1/R2 connection. The R1/R2 connection is the GT-1C7W's primary communication line to the system, and must be present to program and use with the system.
Solution:
Verify the R1/R2 wiring connection between the GT-1C7W and the rest of the system.
