Registration, Warranty, Returns, Refunds, and Repair

This section provides customer support information such as the return material authorization policy as well as methods of obtaining E.E.Tools technical assistance and software updates. All programmers are designed to require a minimum of technical support for both hardware and software. Since we make the product in USA, we supply qualified programmers as trouble-free as possible.

1. Registration

You can register through our website: Registration makes you eligible for:

• Customer support, warranty service and technical assistance
• Notification and special pricing on new products and upgrades

Registration is particularly important if the programmer was purchased from a dealer, a distributor or through your purchasing department.

2. Software Updates

Your programmer is designed to be highly flexible and programmable, allowing it to program a wide variety of chips. Consequently, when a problem does arise, it can usually be fixed with just a free software update. The new software updates are available from our WEB page at Use the new software if you have any other incorrect programming results.

3. Testing the Hardware

Make sure that your programmer works properly before you call us for technical assistance. Refer to Hardware Test section in the Config menu.

4. Quick Self-Diagnostics

In order to provide accurate and fast technical assistance, we recommend that you check the following information before you call our technical support department. We recommend that you obtain the latest software revision before calling our support line with a software problem. Eighty percent of our technical support calls result in asking the user to obtain the latest version of the software.

  • For USB programmers TopMaxII and UniMax, you should install the USB driver in your PC after install PC control software. The USB driver is in either CD-ROM or C:Program FilesEE Tools directory.
  • ProMax-4G will need the USB installation 4 times and ProMax-8G does 8 times. Do not power Off and ON in 30 seconds and you must wait over 30 seconds once you un-plug an USB cable from PC(USB Hub) and plug-in the same cable.
  • Be sure the device selected matches the device being used.
  • For multi-site programmer usage, make sure all devices are identical.
  • For a device that uses an adapter, be sure that the adapter is correctly oriented, seated properly, and the ZIF socket lever is down.
  • Be sure power cord is securely attached to programmer and power pack to wall socket.
  • Be sure that power switch is ON.
  • Be sure that the parallel cable (IEEE standard, 25 pins and wires) is correctly and securely attached to the programmer and PC. The connection must be direct; there cannot be any software keys or locks between the parallel port and the programmer. Most switch boxes may also cause difficulties.
  • You may need to change your printer port [even though it is working fine with your printer] because TopMax/TopMax-8G/Chip Max communicates with your computer via the printer port in a bi-directional mode.

5. Calling Customer Support

E.E.Tools provides telephone technical assistance during normal business hours (9:00 AM to 5:00 PM, Mountain time).

  • Please call our Technical Support Department or your local E.E.Tools distributor while you are at your computer and be prepared to repeat the sequence of steps leading up to the problem
  • Have the following information ready when you call:
    – The invoice number for the user who bought programmer from E.E.Tools.
