Using A Document Holder; Your Hp Keyboard - HP Vectra VE 5/series 2 User Manual

NOTE
If the image on your screen is not stable, the display may require repair or adjustment.
When possible, use a program that has a simple "machine/user interface". Also, screen
information should be displayed in a structured and well organized way.

USING A DOCUMENT HOLDER

A document holder may make it easier to transfer information from a document to the screen
(or if you need to read while using your system).
If using a document holder, it should be at the same distance from your eyes as the screen,
next to the screen, and at the same height as the screen. An alternative location preferred by
some people is to locate the document holder between the screen and keyboard.
To help reduce stress on your neck and prevent eye fatigue, keep the back and forth
movement of your head and eyes to a minimum while using a document holder.

YOUR HP KEYBOARD

Your HP keyboard has a long cable so you can place it in the position most comfortable for you
while you are using the system.
The keyboard has a low profile to prevent excessive bending of your wrists while typing.
Literature suggests that you should not bend your wrists more than 10 degrees up or down, or
more than 10 degrees sideways. Keep your wrists straight by moving your entire hand and
forearm over to use the function keys or numeric keypad.
The ISO 9241 and ANSI/HFS 100-1988 standards
give ample technical recommendations on how to
achieve good readability.
