Operating Guide

It can sometimes be dicult to know what exactly is wrong with Bob if he is not
feeling well or working the way he used to. To make it easier for you to diagnose
the real reason behind Bob’s odd behavior or reduced productivity, he is equipped
with a comprehensive home checkup test — a simple procedure that allows you to
examine each of Bob’s parts independently.
Put Bob in checkup mode
Set Bob’s side power switch to OFF and place him on a light-colored surface.
While holding down the leftmost button on Bob’s cover, turn Bob’s power switch
ON.
Bob will turn on and emit a three-tone beeping tune. The screen will show a word or
a number sign. Bob is now in checkup mode. Do not press any buttons.
