- Texas Instruments Inc. said Tuesday that all owners of its popular 99-4A personal
- computer should contact the company about modifying a part that could give users a
- high-voltage electrical shock. The company said it was discussing with the federal
- Consumer Products Safety Commission the distribution of a transformer adapter cord
- that would protect users from possible danger.
-
- TI spokesman Norman Neureiter said company experiments last weekend showed there
- was a remote possibility the computer's transformer could fail and allow a surge of
- high voltage into the computer itself, perhaps shocking the operator or damaging the
- machine. "There are several hundred thousand in use today, and the majority of
- them (transformer) should be considered defective," Neureiter said. He said the
- company had not gotten any report of one of the computers developing the hazard in
- the field, although "a very small number" had been returned because of other
- malfunctions. "But we've been able to duplicate that kind of condition in the
- laboratory, and we feel an obligation to correct it because it's an extremely
- popular computer," he said. He added that TI itself alerted the safety agency about
- the potential danger. "It is extremely remote that such a condition could occur,
- but if the computer starts heating up, you should just pull the plug out,"
- Neureiter said. The 99-4A has been on the market for a year, he said, but most
- sales have been since October.
-
- Owners of TI 99-4A computers will be located from rebate and warranty cards, the
- company said. People who did not send in cards can get an adapter by calling a
- toll-free telephone number _ 1-800-858-4565, 1-800-527-3550, 1-800-858-4069, or
- 1-800-858-1802. Neureiter said the AC9500 transformer, a small black box between
- the wall outlet and the computer, is purchased by TI from an outside supplier and
- sold with the computer. He said he did not know which company made it.
-
- TI plans to conduct a "green label safety check" on all unsold models, and equip
- them with an adapter cord or a new transformer. A green label will be put on the
- computers' boxes to show that they have been modified. In a statement released
- Tuesday, TI said it could not predict the effect of the transformer problem on 1983
- earnings, but said it expected first quarter earnings this year to be
- "substantially below" those of fourth quarter 1982.
-
- Neureiter said company policy did not permit him to elaborate on the financial
- impact of the transformer problem.
