MX99
CASE 2
If you are using the MX-99 with another brand of
FM tuner, and you find that maximum separation is
obtained with the SEPARATION control set somewhere
between 8and 10, you can usually maximize high-
frequency separation by increasing the value of C25 to
as much as twice its present value of .OOlmfd. (You
may do this by soldering an additional 10% disc capaci-
tor in parallel with C25. Try 470mmf first and stick
with this value if separation is noticeably improved;
if not, try .OOlmfd).
NOTE: In Case 1, the results of removing C25
are favorable in all respects. In Case 2,
the increase in the value of C25 over its
present value of .001 mfd will result in
asomewhat higher background noise level.
The latter effect is not related to the per-
formance of the MX-99 Adaptor, but merely
reflects the actual signal-to-noise ratio
in the tuner over the frequency band con-
taining the multiplexed signal.
6-6. EICO’s SERVICE POLICY
SERVICE CONSULTATION
If you are experiencing trouble that you cannot
diagnose yourself, you are invited to avail yourself of
the EICO Service Consultation Department. The con-
sultant handling your inquiry will make every effort to
diagnose the cause of your particular difficulty based
on the information that you provide. Please be as
thorough as possible. Include the following information
about your unit:
a) Have you made athorough check of the wiring,
checking also for cold solder joints, or acci-
dental shorting between parts, or to chassis?
(Check to see whether abare wire or lead ex-
tends far enough to be shorted when the bottom
plate is put on).
b) Have you checked that the proper tube or trans-
istor is in each socket, and also making proper
contact in the socket? Are all shields firmly
in place?
c) Does the trouble occur at one time or one
operating situation, but not at another time or
operating situation? Be as specific as possible
in this respect.
d) If the unit is of the type that involves alignment
or calibration, be as specific as possible as
to what you have done or not done with regard
to these requirements. If the unit incorporates
tuned circuits stated to be factory pre-aligned,
did you change any settings? If so, whatalign-
ment procedure did you use?
e) Have you observed any pecularity about apart?
If apart appears charred or otherwise damaged
by excessive heat, please say so. If you think
you have damaged aparticular part in the
assembly or wiring, please say so. In con-
junction with the symptoms, the consultant may
be able to determine whether such apart is
likely to be defective.
f) Have you gone through any trouble-shooting
procedure that may be provided? If your manual
includes atable of contacts made at each switch
position, have you checked out the switches
accordingly (if the trouble is such that doing
this would be appropriate)? Have you been able
to make checks of the operating voltages and/or
resistances, if this is appropriate, and your
manual provides atable of voltages and resist-
ances? What are the results of these checks?
Also, have you taken any other trouble-shooting
approaches? What have been the results?
g) If this is high fidelity equipment, please state
the type (magnetic, ceramic, crystal) of phono
cartridge you are using and/or the make and
model number. State the make and model of
your record changer, or turntable and tone arm.
Are the speakers in the same cabinet with
your electronic equipment? If so, describe the
cabinet and the placement of the components.
Please state the make and model of your speak-
ers.
In addition, list any code numbers in red under the
words INSTRUCTION MANUAL on the cover of the
book provided with your unit. If there are no red code
numbers, state this specifically. If the unit bears a
serial number, it is essential that you include this also.
PARTS REPLACEMENT
If it appears that acomponent is defective, and
you desireareplacementfromEICO, address your cor-
respondence to our Customer Service Department.
If you are claiming the right to ano-charge re-
placement under the terms and conditions of the war-
ranty, it is required that you shall have sent in the
registration card within 10 days of the date of purchase,
and that you send back the defective part transportation
prepaid. EICO will make the necessary replacement
at no charge for parts eligible under the terms and
conditions of the warranty. In returning tubes, pack
them very carefully to avoid breakage in shipment.
Broken tubes will not be replaced. Please read the
warranty on the subject of parts eligible for replace-
ment.
Further information required on apart returned
to the factory for ano-charge replacement under the
terms and conditions of the warranty is as follows:
a) Model number and serial number, if any, of
unit. Also any code numbers in red under the
words INSTRUCTION MANUALon the cover of
the book supplied with the unit.
b) Stock number and description of part as given
on the parts list. If the part is not listed (of
itself) in the parts list, it means that the part
is integral with asub-assembly. If the sub-
assembly is not sealed, and the defective part
is definitely identified and easily replaceable
(not more than two connections), you may re-
quest replacement for the particular part. If
the sub-assembly is sealed, or if the defective
part is not definitely identified or is not easily
replaceable (more than two connections), then
remove the sub-assembly and return it to EICO
(less any tubes) for repair or replacement, if
your unit is in warrantee. If your unit is out
of warrantee, you are generally advised to
order areplacement sub-assembly.
c) Describe as completely as possible the nature
of the defect, or your reason for requiring
replacement.
FACTORY REPAIR SERVICE
EICO maintains aFactory Repair Service Depart-
ment for in-warranty or out-of-warranty repair of
E ICO equipment. If is intended to serve those customers
who are not adequately familiar with electronics to
make use of the EICO Service Consultationfacilities, or
whose difficulties cannot be solved by correspondence.
For allout-of-warranty units, there is aminimum
labor and handling fee. For the Model MX-99, this fee
is $7.50. Charges for components replaced are addi-
tional to the minimum fee.
For in-warranty completed kit units, there is a
minimum labor and handling fee. For the Model MX-99,
