How to alter the REMOTE ON DURATION in my Nikon D40?

I've read some things online about changing this option but on my nikon's D40 i can't access any other options after the 6th one. I have no other pages or options to scroll down to on custom settings. I'm quite confused about how to access this or to change the REMOTE ON DURATION differently.

it's said in places that its the CS17 setting, but like i said i can't go any further on my settings that the 6th one, the no memory card? Option.

i'm trying to access the remote on duration as can get quite annoying when the remote setting turns itself off when i'm using it.

I just had a look.
Scroll down to No memory card --- then just keep scrolling down, there are another two pages of options incuding the one you're looking for.
Remote on has settings of 1, 5, 10 and 15 mins.

---EDIT EDIT EDIT ___

Just realised why you can't see it--
You need to have the CSM menu set to FULL, otherwise you only get six items in the Custom Settings list, not the three pages there normally is.

. You've got yours set to SIMPLE

To change it ---

Scroll to SET-UP MENU (The spanner) --> CSM/setup menu --> and select FULL
