Before we start to explain the various Service Settings, it is important to know the

correct procedure to get access to the Service Menu.

There are two ways to get access to the Service Menu one method will allow the

user to carry out a Service reset or a Master reset.
This will be covered first.

There is a reset switch at the back of the EPOS which is used to get access into the
Service programming area, whenever this switch position is to be changed you must
follow this procedure: -

First Power off the UP3300.
Then move the Service switch away from the run position,

Then Power the UP3300 back on.

You can then return the switch to the run position.

This procedure will give you access into the Service screen and ask you to select a

Program Reset or Master Reset, after confirming the appropriate selection the
Service Menu will be displayed, ready for your programming.

It is important to remember, if the reset switch is moved without turning off the

power on the UP3300 then you may cause damage to the memory of the machine.
The other method of getting into the Service position, which will be more commonly
used to carry out changes to settings, is by entering the Secret Service code but this

will not give you the option to Program Reset or Master Reset.

The Service Secret code is an eight digit code that can be set to any eight digit

number you require, but this code is set as 9,9,9,9,9,9,9,9 (that is eight nines) from

Master Reset.

To get access from the main trading screen, you should press the MODE key; this
will then drop down a menu, which will contain various mode selections.

If you now enter the eight-digit service secret code followed by the Enter or Cash
key, you will be in the Service Mode.

Some of the settings are self explanatory such as G.T settings and Z report counter
but I will explain the relevant ones.
