The ENTER/MENU key is also used to enter selections or enable programming and calibration steps.

The EXIT key returns to the previous menu level.

The INFO key provides detailed instructions and explanations during programming and calibrating procedures. It also provides troubleshooting tips for all faults and warnings that may occur during calibration or continuous operation in process.

Navigation Keys

The four Navigation keys arranged around the ENTER/MENU key operate in an intuitive manner similar to the navigation keys on a computer keyboard. During menu operation, these keys are used to move the highlighted screen selection to another adjacent screen item. During tag entry, the left key is used to delete entries during active alpha-numeric character entry.

Alpha-numeric Keypad

The alpha-numeric keypad has 12 keys as outlined below.

•Nine keys are alpha-numeric

•One key is a dedicated “1” key

•One key is a dedicated “0” key

•One key is a dedicated “.” (decimal point) key

The alpha-numeric keypad operates the same as entries on a mobile phone. The nine alpha- numeric keys have multiple characters that can be entered for tag entries or during programming and calibration steps. Character selections are made by pressing the key multiple times to toggle to characters that are available on each key.
