OPERATION
CONTROLS AND INDICATORS
Operating controls and indicators on the Series 500 Standard QWERTY Keyboard are shown in Figure 4 and described in Table 1. Because most Series 500 POS Keyboards are customized to match the user's needs, keyboard layouts and the function of the keys may vary widely from the one shown in Figure 4. Although the location of keys may differ among keyboard and types of keyboards, the function of the controls and indicators described in Table 1 pertain to all keyboard types. The operator should become familiar with the controls, indicators and other operating features of the keyboard. For typical keyboard layouts of other Series 500 POS Keyboards, refer to Appendix A.
