PROGRAMMING:

The CNTV requires custom configuration in order to program. Prior to closing your order, it was necessary to complete the Crestron CNTV Worksheet. This worksheet permits Crestron to prepare a specific configuration file based on the intended use of the CNTV. Append this file to the overall control system program in SIMPL Windows. For more details regarding programming the CNTV, consult a Crestron technical representative.

TEST/TROUBLESHOOTING:

Table 4 provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron technical representative.
