Guide population.
On initial set up when entering Guide PIG will suspend whilst it receives guide data, note this can take some time, but it should only be a one off, unless of course you factory reset.
Once all guide data is retrieved it is stored on board and updated from which ever transponder you happen to be watching, and/or overnight.
Note: If recording and guide is entered - N/N should be available for all channels immediately but it takes some time for the unit to retrieve data and populate all of the guide.
