# POS Control - Configuration
### Number of Revenue Centers Set the number of revenue centers that will be used. The default number is 4. The minimum is 1 and the maximum is 32. Examples of common revenue centers include "Dining Room", "Take Out", "Bar", "Delivery", etc. Revenue centers are sometimes referred to as "profit centers". {% hint style="info" %} NOTE: For changes to the number of revenue centers to take effect, workstation data ned to be re-created. (Server Control > Workstation > All Workstation Data) {% endhint %} #### Number of Modes Select a multiple of 4 modes up to a maximum of 32. Modes can be used in many different ways. Typically, modes represent price points for sales items. #### Number of Tables This field refers to the number of tables, and the actual table numbers, used in the Maitre'D POS system. A maximum of 9,999 tables is available. If you intend to create sections, and assign numbers in each section, you could set up 500 tables and use 101, 102, 103 ... for section 1 and 201, 202, 203 ... for section 2. Order numbers begin with the next number after the number programmed here. (e.g. # of tables = 500 order # begin at 501). #### Non Taxable From the drop-down list, select a 0% tax that will be assigned to non-taxable divisions. This entry will also be used to replace the usual taxes on a check, for tax exempt customers. {% hint style="info" %} NOTE: To use this feature, also enable the Non Taxable option in Point of Sale Control > Employees > Configuration > \[Select a Config] > Invoice. {% endhint %} #### Check \# This field cannot be modified. On a new installation or following a sales deletion, this value will be set to 100000. This value will increase by 1 every time a check is printed. In normal use, this field tells you what is the last check number that was printed by Maitre'D and gives a rough idea of how many checks were printed since the first day the system was used. #### Language Select the main language to be used at the point of sale workstations. This will be the default language that is used on the POS screens before the employee logs in. For this language to also be used after the employee logs in, enable the Main Language option from Point of Sale Control > Employees > Employees > \[Select employee] > POS Operation > Option. #### Second Language Select an alternate language to be used by employees after they logon to the POS workstation. For the second language to also be used after the employee logs in, disable the Main Language option from Point of Sale Control > Employees > Employees > \[Select employee] > POS Operation > Option.
