Change of date?

Hi,

On the 150,

Set switch to X mode.
Type date as MMDDYY
Press CH button.

Remember, the 150 has no time system, so you must set the date every day.

I've never seen a 220 before, so I will have to guess with this machine. Try the 290 method:

Turn key to PGM mode.
Type date as MMDDYY or DDMMYY depending upon your country.
Press SUBTOTAL

Hope this helps.
