CR100A

RECALL

REVISION

NOTIFICATION AND DIRECTIONS

Revision Date: February 21, 2008

ORIGINAL NOTICE OF RECALL

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 one 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 CR100A 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, Bogen 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 1-800-999-2809, option 1
for a return authorization number and return the unit to Bogen for repair at Bogen’s 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 Support 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 that 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 provide 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.

If you have any questions regarding this voluntary recall, please direct them to Bogen
Customer Service at 1-800-999-2809, option 1.

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 40th 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.

METHOD 2 – FIELD REPAIR OF THE UNIT

Test: A simple test using a multi-meter will diagnose if the wrong resistor was

installed. Please refer to pictures below.

Read the resistance between the neutral prong (wide blade) of the AC plug and
the left most screw terminal, looking at the rear of the CR100A.

The resistance must read greater than 9 Meg Ohms.

Neutral prong

Section revised 2/21/2008

If the resistance read is less than 9 Meg Ohms, the units must be repaired.

FIELD REPAIR PROCEDURE

1. Disconnect from AC line and remove the top cover of the CR100A.

2. Locate the resistor R3 on the rear PC board of the CR100A.

3. Lift the PC board off the nylon stand-offs holding the PC board in place.

Use needle nose pliers to pinch the tips of the stand-offs protruding
through the PC board.

4. Remove the existing R3 resistor and replace it with a 10 Meg Ohm, ½

th

watt, resistor (color code Brown/Black/Blue, 4

band color does not

matter).

5. Re-seat the PC board and replace the top cover.

Note:

Resistors for this repair (part number 75-5437-106) are available from Bogen free of
charge by contacting Bogen Customer Service at 1-800-999-2809, option 1.
