A disabled channel will not appear in any measurements but will remain in your channel plan (until you delete it). You can enable or disable any channel in one of two ways:

TIP:
Method #1 (below) is especially useful when you are enabling or disabling multiple channels in your plan.

Method #1:

Press the PLAN softkey on the SELECT A DOWNSTREAM PLAN screen. Use the arrow keys to highlight Enabled Channels on the pop-up menu and press ENTER.

On the ENABLE/DISABLE CHANNELS screen, use the arrow keys to highlight the channel you intend to edit and press the ENABLE softkey to enable or disable (depending on its prior status) that channel. Repeat the process for other channels as necessary.

Method #2:

Press the PLAN softkey on the SELECT A DOWNSTREAM PLAN screen. Use the arrow keys to highlight Edit on the pop-up menu and press ENTER.

On the SELECT A CHANNEL TO EDIT screen, use the arrow keys to highlight the channel you intend to edit and press the EDIT softkey. On the EDIT CHANNEL screen, use the arrow keys to highlight the "Enabled" parameter and press ENTER. Highlight your preference - "Yes" or "No" - and press ENTER to complete the edit.

TIP:
You cannot disable all of the channels in a plan; at least one channel must remain enabled.
