<p align="left"><b><font face="Arial" size=2><u>SYMPTOM</u></font><font face="Arial" size=2>:
</font></b><font face="Arial" size=2>Due to an error in manufacturing
of EMI cover in the power supply, it is possible that the cover could
deflect or pierce the insulation of the input AC line and neutral conductors.
Should the EMI cover pierce the input AC power conductor insulation, depending
on which conductor (line or neutral) contacts the shield, either a branch
circuit breaker will trip or a small current can flow into safety earth
ground (green wire). If current flows in the neutral to earth ground path,
some erratic station operation could occur, such as degraded hum and noise.
</font></p>
<font face="Arial" size=1> </font><u></u>
<p><b><font face="Arial" size=2><u>WARNING</u></font><font face="Arial" size=2>:
<u>There is a risk of shock in a non-code-wired facility and/or improper
grounded station.</u></font></b></p>
<u><b><font face="Arial" size=1> </font></b></u>
<p><b><font face="Arial" size=2><u>CAUSE</u></font><font face="Arial" size=2>:
</font></b><font face="Arial" size=2>A correctly designed EMI cover is
slotted to avoid contact with the AC input and does not have RFI "fingers"
above the AC conductors. On the incorrectly manufactured covers that are
the subject of this Bulletin, the "fingers" are above the insulated AC
conductors, and these "fingers" could come in contact with the AC mains
power. Incorrectly manufactured EMI covers were installed in Quantar,
Data Basestations and Comparator's AC power supplies. Both covers have
the same part numbers (pt. no. 15D85034U11). The only way to identify
the suspect covers is to visually inspect the cover, refer to samples
below.</font><b><font face="Arial" size="2">	 </font></b></p>

<p><b><font face="Arial" size="2"><u>PROCEDURE TO IDENTIFY, INSPECT AND
REPLACE EMI COVER</u>: </font></b></p>
<ul>
<li><font face="Arial" size="2">Determine if any of your customers have
stations on the above list.</font></li>
<li><font face="Arial" size="2">If they do, <b><u>before going to the
site</u></b>, call System Support Center @ 1-800-221-7144 and request,
at no cost, EMI covers to carry with you to replace any defective covers
you may find for that customer site. At that time, the System Support
Center will open a case to track any defective covers you may discover.</font></li>
<li><font face="Arial" size="2">After receiving the covers, visit your
customer sites to inspect the stations. </font></li>
<li><font face="Arial" size="2"><u><b>TURN OFF AC POWER TO THE STATION</b></u>
prior to beginning your on site inspection.</font></li>
<li><font face="Arial" size="2">Remove the power supply from the Quantar
chassis. </font></li>
<li><font face="Arial" size="2">Remove the power supply unit cover.</font></li>
<li><font face="Arial" size="2">When the unit cover is removed, the EMI
cover is plainly visible near the AC mains inlet connector. </font></li>
<li><font face="Arial" size="2">The EMI cover has a shiny rectangular
shape of approximately 3.0"x 4.5" and a "X" shaped
raised ridge across the top. </font></li>
<li><font face="Arial" size="2">A defective cover can be readily sighted
by noting the closeness - perhaps touching - of the cover's spring fingers
to the insulated AC "Fast-On" connectors that carry AC from
the AC power inlet into the power supply circuitry. </font></li>
<li><font face="Arial" size="2">Properly made covers <b>HAVE NO</b> spring
fingers in the area of the AC connector.</font></li>
<li><font face="Arial" size="2">Replace the incorrect cover. </font></li>
<li><font face="Arial" size="2">Restart station.</font></li>
<li><font face="Arial" size="2">Call the System Support Center, refer
to the case number that was opened and supply a list of serial numbers
of stations inspected and serial numbers of stations where the EMI covers
were replaced.</font></li>
<li><font face="Arial" size="2">Submit warranty claim.</font></li>
</ul>
<p><font face="Arial" size="2">Authorized Motorola Service Shops will be
allowed 15 minutes labor time per station to inspect, and if required
install the new EMI covers, plus travel. Servicers should submit a standard
labor warranty claim form and make reference to this bulletin number.</font><b><font face="Arial, Helvetica, sans-serif" size="3">
