Transformer units supplied with the Texas Instruments 99/4A home computer
Description
Washington, D.C. -- In cooperation with U.S. Consumer Product Safety Commission, Texas Instruments Incorporated said today that it is conducting a voluntary program of providing transformer adapters free of charge to correct a potential defect recently discovered in one model of the transformers supplied with the Texas Instruments 99/4A home computer. Over four hundred thousand transformer units are involved. The transformer is the small black box which plugs in between the computer and the electrical outlet. Consumers are instructed to plug in their adapter between the transformer and the wall outlet.The company reported it had found by laboratory testing that there is a remote possibility that a failure of the transformer could result in certain metal parts of the computer console becoming electrified thus presenting a possible shock hazard. Neither the Consumer Product Safety Commission nor Texas Instruments has received any report of hazardous incident or injury from the hundreds of thousands of Texas Instruments home computers in use. The 99/4A model home computers have been sold in a variety of retail outlets over the past year at suggested retail prices of $450 and $375 with $100 rebate in effect since September 11, 1982.All owners of the 99/4A known to the company through rebate cards or warranty cards will receive the adapters automatically by mail. The company asks owners who are not sure their names and addresses are in its files to call the Texas Instruments toll free numbers (800-858-4565 or 800-527-3550) (Texas only: 800-858-1802), and request that the adapter be sent to them.Prior to receipt and installation of the adapter plug or cord, the company advises consumers to unplug and discontinue using computer if any sign of transformer overheating, unusual odor, or computer malfunction occurs.Texas Instruments is also instituting a green "Safety Check" label for easy recognition by customers that the transformers in inventory at retail stores have been inspected and modified as necessary. A similar label will be placed on the transformer and its wrapper inside the box.Consumers who desire further information or who have questions regarding the Texas Instruments 99/4A home computer may call CPSC's toll free hotline: 800-638-CPSC.

Frequently Asked Questions
Follow the consumer action instructions in the recall notice above. Most recalls require you to stop using the product and contact the manufacturer directly, either by calling the toll-free number listed in the official CPSC notice or by visiting the manufacturer's website. You generally do not need a receipt or original packaging to claim a remedy. The manufacturer is legally required to provide the remedy (Replace) at no cost to you.
No, you should stop using the product entirely, not just unplug it. Electric shock and fire hazards in recalled electrical products often involve internal wiring defects, faulty components, or insulation failures that can cause harm even after the product has been off for a period of time. Do not attempt to repair the product yourself. Keep it unplugged and stored safely until you receive the manufacturer's remedy. If the product has already shown signs of overheating, sparking, or discoloration, handle it carefully and consider contacting your local fire department for guidance on safe disposal.
In most cases, no. CPSC-coordinated recall remedies are designed to be accessible without proof of purchase. Manufacturers typically ask consumers to self-certify ownership and may ask for photos of the product or its serial number. Some manufacturers request that you mail in a portion of the product (such as a cut cord or removed component) as proof of disposal. Check the specific remedy instructions for this recall for exact requirements. If you registered your product at the time of purchase, the process is usually even simpler.
If the original manufacturer has gone out of business, the recall remedy may no longer be available through them. In this case, contact CPSC directly at 1-800-638-2772 or cpsc.gov for guidance. If the brand was acquired by another company, the acquiring company may have assumed recall obligations. In some cases where a remedy is unavailable, CPSC advises consumers to safely dispose of the product. If you were injured by the product of a defunct company, consult a product liability attorney, parent companies, distributors, and retailers may still bear liability in some circumstances.
