If you set the all line and set restrictions to no restrictions, you are not restricted from making any calls. I don't think it's the phone system requiring this 4 digit code. Are you sure all your lines are set with the same long distance provider. Did the lines in the dial 8 group require a code. (ie some users had the long distance provider set up their lines to need a code entered to charge calls off to different job codes, so they can distribute the charges correctly).
You should now be able to call 9+1+area code+number, with no restrictions.

This is a "Class Of Service" function. The out-ot-box default setting is generally 3 rings. However, different extensions can be set to each forward to VM after differing number of rings, but each phone will need to be assigned its own specific Class Of Service and the Call forward timers defined accordingly in those classes of service. Normally your system manager will define several classes of service with different forward-no-answer timers then assign those COS to people who request specific call forward timing. The default is usually 3 rings. Hope this helps

Descale the boiler with citric acid.

1. Turn off the machine and let it get cool
2. Dissolve about a tablespoon of citric acid in the water reservoir.
3. Turn on the machine and then pump about a cup of solution out of the boiler vent using the hot water switch.
4. Turn off the switch. Close the vent
5. Let the boiler heat up for about 5 minutes.
6. Shut off the machine. Let the acid work for about 30 minutes.
7. Check the level in the reservoir.
8. Turn on the machine and then pump about a cup of solution out of the grouphead using the brew switch.
9. Turn off the brew switch.
10. Repeat steps 5,6, 7, 8, and 9 until the water runs clear.
11. Wash out the reservoir.
12. Turn the machine on. Pump a full reservoir water out the grouphead using the brew switch.
13. Refill the reservoir.
14. Have some coffee

Adjust the grind of the coffee you are using finer, I don't know what type of grinder you are using but I will assume it is a commercial one. Adjust it about 2 numbers towards fine that will be a good start.

This camera can use SD or SDHC cards up to a maximum of 8GB (gigabytes). These cards come in different "class" ratings. A class 4 card will provide faster access than a class 2 card. Video cameras like faster access cards and some specify that the card should be class4 or class 8. The card will have a number printed on it, maybe inside a capital letter "C" if it is faster than a class 1.

The manual for this camera does not specify a minimum class rating for the card.

check your metal hous from pump to tank maybe hous is old

Espresso Dr. Located at Fortitude Valley. Ask for Michael.

I have a TX-902 owners manual.
It states:

Classified Memory Function. The memory can be divided for different users or programs of stations.
How to classify stations. With this model, six classes (Class A to F) are available and stations can be memorized in any class. A total of 30 stations can be memorized in any class. A total of 30 stations can be memorized.

1. Tune in the desired station.
2. Press the MEMORY button. The MEMORY indicator will flash for 8 seconds.
3. Press the desired Classified Memory button (one of buttons A to F). The station is memorized in the selected class with the memory number which is the smallest of the unoccupied numbers in the class.

By repeating the operations above, up to 30 stations can be memorized. Any more will produce "FULL" notice.

How to cancel memorized stations:
Retrieve the class number you want to cancel and then press the MUTE/MODE button while holding down the MEMORY button. Another station can be memorized with the memory number which has been cancelled.

Hope this helps.

Sounds like your Rancilio needs a service, this problem could be caused by the boiler not working correctly, possibly a leak from the boiler or a valve malfunction causing a drop in pressure.
