# Advanced POS UI - Left-Handed Operation

### Left-Handed operation for the Advanced POS User Interface

This article describes how to use the Advanced POS User Interface in left-handed mode. This configuration is applied at the employee level, which means that every employee can use the POS in left-handed or right-handed mode, according to their personal preference.

***

### Enable Left-Handed operation

By default, the POS User Interface is configured in right-handed mode, as approximately 90% of the world's population is right-handed. This procedure shows how to configure the POS User Interface to left-handed mode for a single employee. Repeat this procedure for every left-handed employee.

1. Logon to the Maitre’D Back-Office with appropriate credentials. (Distributor or System Owner)
