Keypad
The keypad allows for control of the handheld. Each button on the keypad may have multiple functions.
These different functions are used depending on the current screen or function that is being used by the
operator.
Dual Purpose Keys
Some keys, such as the keys with numbers on them, have a dual purpose. For example, the upper left
button. The top row, 1ABC, is used for character entry. For example, when an operator is prompted to
enter a VIN or PVI, the keys with numbers & letters will enter in their corresponding characters. During
these prompts, when the operator presses the ‘1 ABC’ key, then 1 will be entered. Otherwise, when not
entering characters, this ‘LF’ key will be active. Sp pressing this button will initiate a read of the ‘LF’
(that is Left Front) stem.
How to enter Letters
Letters are entered with quick a succession of presses of the same key. As these quick presses happen
the cursor will scroll through the number and letters associated with that key. For instance if the
operator wants to enter the character ‘R’, then he will press the ‘6’ key. After that he will quickly press
the same key 3 more times until the cursor displays ‘R’. Then he will pause for a short time, the ‘R’ will
be entered and the cursor will move over, ready for the next character. If the key is pressed beyond the
last character defined for that key, then it will simply “scroll back” to the original number, and keep
scrolling through that keys associated characters until he stops pressing the key.
The settings menu has an option to disable letters and only allow number entry for a vehicle identifier.
