As long as I'm on the topic:
PIN setup for all I-guide based boxes:
1) Set up a Purchase PIN
Menu, Menu (Main Menu), Setup, PINS Setup, Enter New Purchase PIN
I recommend using something non-identifying (you'd be amazed how many kids will try birthdays and last 4 SSNs to get past a purchase pin) and if you write it down, don't put it where anyone else can get to it or stumble upon it.
The Purchase PIN will come up whenever someone attempts to order any title (VOD or Pay Per View) that would incur a charge on your bill.
2) Set up a Ratings PIN and lock ratings you want to keep out
Menu, Menu (Main Menu), Parental Control
Again, same rules as before and this PIN should be DIFFERENT than your purchase PIN, this way if they do figure one out, they still can't buy anything without the other code.
When you lock down programming you can choose Movie Ratings and TV Ratings - I recommend locking both Adult and the TV-MA ratings - alot of adult content on VOD is rated as a program, not a movie, as such it carries the TV-MA rating. You can also choose to lock out entire Channels as well (I know alot of parents like to lock out MTV or other channels with content they do not want their kids viewing.) you can also opt to hide Adult content titles and descriptions - Which is one guide feature I have not seen on the Moxi guide - just the TV Guide based boxes.
Locked content should have a Padlock appearing on the grid listing and it should not allow the content to be pulled up for a description without entering the Parental Control lock. Once that's pulled up, if an order is made it should not allow order verification without first putting the Purchase Pin in
Run through your codes and try them out - you should be able to click on a locked program and it will request the Parental Control PIN when the channel comes up. You should be able to click on a title that has a dollar value and it should request the Purchase Pin before you can order it.
If you order a locked title in advance (Pay-Per-View) you only need to know the Purchase Pin at the time of order, however it won't let the box tune to it once it comes up without the Parental Control PIN. If you can't tune to it - it won't allow the order to fully go through.
PINS can be cleared if the box is Initialized, which wipes the box and reloads it, however it won't clear from a power outage (intentional or otherwise) - Check your PINS regularly just to make sure they haven't been cleared. -
One way to know if the box has been cleared is to change the Guide Color - if you notice the color change back to the default, chances are your PINS have been set back to default (none) as well.
When there is no guide data or the program is unrated the box will assume it should be blocked (this way they can't get around the restriction by power-cycling the box) - you can change this under the Parental Controls setup or if you are going to be watching TV for a while you can use the Master Lock option to unlock the box temporarly.
PINs keep you in control of who watches what! - Just remember each box keeps it's setup locally, so take the time to lock all the boxes you want to prevent unauthorized access to!
Each account has a PPV Credit limit. If you want to to be completely sure there are never any suprises, have it dropped to a level within your budget (I keep mine at $10 should we want to order a move once in a while, but low enough to keep a major spending spree from happening) -
VOD checks the credit limit immediately - so if you have a credit limit of $10 and attempt to order a $13.99 adult title, it will kick it out.
Pay-Per-View only checks once a day, so it will keep allowing orders (up to 10 titles) until it checks the limit and sees you've exceeded it. So with PPV, as long as the credit limit has not been exceeded you can order anything (even over the limit) until it does it's daily check.
