1、 CR100A RECALL CR100A RECALL REVISION REVISION NOTIFICATION AND DIRECTIONS NOTIFICATION AND DIRECTIONS Revision Date: February 21, 2008 RadioFans.CN 收音机爱 好者资料库 Bogen Communications, Inc. | 50 Spring Street Ramsey, NJ 07446 | Tel 800-999-2809 Page 2 ORIGINAL NOTICE OF RECALL ORIGINAL NOTICE OF RECALL

2、 Bogen is undertaking a voluntary recall of certain AM-FM Tuner/Cassette Players, Model CR100A, sold between February 2006 and November 2007. Bogen believes that an incorrect R3 resistor may have been installed in units sold by Bogen during that time period. Our records reflect that you purchased on

3、e or more of the units in question. The R3 resistor is located on the power supply pc board. This resistor connects to the neutral terminal of the AC cord. This kind of connectivity is normally implemented by manufacturers in order to use the AC cord as an antenna. If the AC outlet into which the CR

4、100A connects is wired incorrectly such that the neutral and the hot wires are reversed, the presence of high voltage on a bare screw terminal for the antenna may present a shock hazard if the unit contains the incorrect resistor. Of all the units sold by Bogen during the time period in question, Bo

5、gen has only received one report of a minor shock occurring. Although we believe that the likelihood of these two events occurring may be remote, in an abundance of caution, Bogen is undertaking this voluntary recall. If you have any of these units in stock, please contact Bogen Customer Service at

6、1-800-999-2809, option 1 for a return authorization number and return the unit to Bogen for repair at Bogens cost. Bogen will return the repaired unit to you and will bear all shipping costs. If you have already installed any of these units at customer locations, please contact Bogen Technical Suppo

7、rt at 1-800-999-2809, option 2 for instructions on how to test the units in place. If, as the result of such tests, any installed units are determined to have the incorrect resistor, Bogen will provide you with the proper resistors and instructions for making the repairs on-site. It is imperative th

8、at you fully comply with these procedures. Failure to comply can result in liability to your company. If you have sold any of these units to Dealers or end-users, please provide this recall notice to them immediately via certified mail, return receipt requested or other delivery method that will pro

9、vide you with a receipt for delivery. Please retain all receipts. It is imperative that you fully comply with these procedures. Failure to comply can result in liability to your company.

All affected units must be either returned for

11、 repair, credit, or be repaired in the field. Model: CR100A Date Code: All Serial numbers starting with the first 4 digits 0540. 05 represents the year 2005; 40 represents the 40th week of the year 2005. Earliest Sales Date: February 2006 for units under consideration. Hazard: If connected to an imp

12、roperly wired AC outlet, where the hot and neutral connections are reversed, the CR100A can present an electrical shock hazard at the left most antenna terminal. Description: An incorrect value for resistor R3 may have been installed in the suspect lot. The correct value for R3 is 10M ohm. The insta

13、lled value may be 10 ohms. R3 is located on the power supply PC board. This resistor connects to the neutral terminal of the AC cord. This kind of connectivity is normally implemented by manufacturers in order to use the AC cord as an antenna. If the AC outlet into which the CR100A connects is wired

14、 incorrectly such that the neutral and the hot wires are reversed, the presence of high voltage on the left most screw terminal for the antenna connections may present a shock hazard if the unit contains the incorrect resistor. Remedy: There are 2 methods that can be used to remedy this issue. 1. Th

15、e recommended method is to return the product to Bogen. 2. The second method is to test and repair the unit in the field. Note: A simple resistance test with an ohm meter can determine if the unit has the incorrect resistor installed. See the Test section of method 2 on page 6. RadioFans.CN 收音机爱 好者资
