Troubleshooting

Pro-Bot Beeps

When Pro-Bot’s power switch is on, but Pro-Bot has not moved and no keys have been pressed for 3 minutes, Pro-Bot makes a distinctive sound and its screen goes black to preserve battery life. This sound reminds you that Pro-Bot is still on. If you are through using Pro-Bot, turn off the power switch. If you want to continue using Pro-Bot, press any key and Pro-Bot will come back to life and be ready to go.

Recharging Pro-Bot

Pro-Bot’s internal, rechargeable battery powers its motors, lights, and sound. Sluggish Pro-Bot movement indicates the battery may be weak. Here are tips and techniques for recharging Pro-Bot.

Insert the USB cable into the charging socket on the rear of your Pro-Bot.

Connect the other end to a spare USB port on a PC or laptop. Alternatively, connect to a USB charging plug.

If you have the Pro-Bot docking station, then place the Pro-Bot into the docking station and connect the power cable.

The green LED in the left eye will turn on to show that the Pro-Bot battery is charging.

The green LED in the left eye switches off when the Pro-Bot is fully charged.

It may take up to 2 hours to fully charge the Pro-Bot if the battery has been fully discharged.

Once fully charged your Pro-Bot will have approx. 8 hours of normal usage, approx. 2 hours when in continuous use.

Battery life will be extended if the battery is recharged when power is low rather than allowing battery to become completely exhausted.

Always fully charge your Pro-Bot before storing for long periods. It is strongly recommended that the Pro-Bot is recharged every six months.

Changing the CR2032 Battery (older Pro-Bots only)

In older Pro-Bots, its memory is powered by a CR2032 “watch” battery. This battery keeps Pro-Bot’s memory active even when the power switch is turned off to maintain the contents of the Main program and all subprocedures between Pro-Bot sessions. The CR2032 battery should last a year or longer. When the battery requires replacement, a message appears on the Pro-Bot screen when Pro-Bot is turned on.

To replace the CR2032 battery, turn Pro-Bot over and locate the battery compartment at the back of Pro-Bot’s underside. The battery compartment has a small square door held in place by a metal screw. Use a screwdriver to loosen the screw and remove the door. Gently dislodge the battery with your finger or the flat edge of a small screwdriver. Insert the new battery by slipping it under the lip of the battery holder and pressing it into place. Replace the battery compartment door and screw it shut.

Care and Maintenance

To clean, wipe Pro-Bot gently with a clean, damp cloth.

Keep Pro-Bot away from direct sunlight and heat.

Do not allow Pro-Bot to come into contact with water or other liquids.

Pro-Bot is Non-Responsive

When turned on, nothing displays on the screen of a non-responsive Pro-Bot and Pro-Bot does not respond to button presses. This indicates that Pro-Bot needs to be reset. Turn Pro-Bot over and find the small hole labeled Reset at the bottom left of the underside of Pro-Bot near the switches. Bend a paper clip so that one end sticks out or obtain a toothpick which fits in the hole. Be sure batteries with power are installed with the correct polarity. Turn Pro-Bot on. Gently push the end of the paperclip or the toothpick in the Reset hole. Pro-Bot beeps and springs back to life.
