Approximately 600 Charter Cable Co. subscribers received letters this weekend alerting them that their Motorola cable boxes are subject to recall.

Motorola contacted Charter -as well as other cable companies in the region – to let them know quality testing showed that about 1 percent of boxes produced from March to May have defects in the power cord interface, said Matt Favre, Charter’s director of operations. If mishandled, the cord could cause a shock.

Charter has notified by mail all customers potentially impacted by the situation, Favre said. In his letter he explained that there is no danger so long as customers do not tamper with the cable box. Favre also advised them to always remove the cord from the power source before removing it from the box or television.

&uot;I don’t want to alarm or scare people,&uot; he said. &uot;This only involves a small percentage of the boxes but Motorola is being pro-active.&uot;

&uot;Customers don’t have to do anything about this,&uot; Favre said.

If customers call Motorola’s toll-free number, 1-866-246-0768, a technician will come out, inspect the box and replace it if necessary.

To date, no Charter customers have reported problems associated to the power cord, he said.
