Bogen Communications Inc. is recalling certain CR100A AM/FM Tuner/Cassette Player
units due to a potential shock hazard. All affected units must be either returned for 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 40
th
week of the year 2005.
Earliest
Sales Date: February 2006 for units under consideration.
Hazard:
If connected to an improperly 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 installed 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
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. The 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.
