PREFACE TO THE PK-232 OPERATING MANUA
Please read this preface in its entirety. t contains information about how to receive warranty ser-
vice from Timewave and Timewave's software update policy.
RF Interference Information To User
This PK-232 has been certified under Subpart J of Part 15 of the FCC rules.
This equipment generates and uses radio frequency energy. f not installed and used properly, in
strict accordance with AEA's instructions, it may cause interference to radio and TV reception. t
has been type-tested and has been found to comply with the limits of a Class B digital device in
accordance with the specifications in Part 15 Subpart J of the FCC rules, which are designed to
provide reasonable protection against such interference in a residential installation. However, there
is no guarantee that interference will not occur in a particular installation. f this equipment does
cause interference to radio or TV reception, which can be determined by turning the PK-232 on
and off, the user is encouraged to try and correct the interference using one or more of the follow-
ing measures:
o Re-orient the antenna of the device receiving interference.
o Relocate the PK-232 or computer with respect to this device.
o Plug the PK-232 into a different outlet so the PK-232 and the device are on different branch
circuits.
f necessary, the user should consult the dealer or an experienced radio/TV technician for additio-
nal suggestions. The user may find "How to dentify and Resolve Radio-TV nterference Problems",
a booklet prepared by the FCC, helpful.
YOU MUST USE SH ELDED CABLE FOR ALL CONNECT ONS !

Welcome
Congratulations!! You've purchased another fine Timewave product.
PLEASE, before we go any further, may we ask you to F LL OUT AND RETURN the Warranty Regis-
tration Card, which has been packed with your PK-232 system.
Product Update Policy
From time to time Timewave may make available updates to the design of its products. We can on-
ly tell you about these updates if we have your warranty card on file. PLEASE SEND T N if you
have not already done so.
In Case of Trouble
Application and troubleshooting assistance may be had by calling Timewave from 9:00-12:00 A.M.
or 1:00-4:00 P.M. in St. Paul, MN. Ask for the Technical Support Department. The phone number is
651-489-5080. Please have your PK-232's serial number and version date of the software available.
The version date is on the first screen that comes up when you turn on the PK-232. We will also
need to know the nature of any other equipment connected to the PK-232.
You may wish to attempt to solve problems locally, using other hams or an Timewave dealer. With
over 100,000 PK-232s in use, a helpful Amateur with equipment similar to your own may literally
be just around the corner. Substituting another PK-232 that you know is working properly for your
questionable one is a diagnostic technique that will check out the rest of your station. You may al-
so try running your PK-232 in another station if possible.
Timewave provides Technical Support for its line of amateur radio equipment by way of your per-
sonal computer and modem on the internet! Timewave's eMail addresses for service and tech sup-
port are [e-mail] and [e-mail].
f you call for assistance, please have your PK-232 up and running beside the phone. Our Support
technician will likely ask you to perform certain keyboard routines to aid in diagnosis. f you have a
voltmeter handy, you might have the PK-232 open so you can report measurements to the Support
technician.
Many of the Timewave products that are sent to us for repair are in perfectly good order when we
receive them. There is a check-out charge of $40 for units returned to us in working order. Please
perform whatever steps are applicable from the installation sections of this manual.
PLEASE DO NOT RETURN THE PK-232 TO US W THOUT CONTACT NG US FOR PERM SS ON AND
AN RMA NUMBER. WE WOULD L KE THE OPPORTUN TY TO TROUBLESHOOT THE PROBLEM OVER
THE PHONE F RST, SAV NG YOU BOTH T ME AND MONEY.
f the unit must be sent in, we will give you a Return to Manufacturer Authorization (RMA) number
over the telephone. This number allows us to track your unit and provide you with its status.
Please write this number on the outside of the box so we may process your unit as quickly as pos-
sible.

We will need YOUR street address for UPS return - be sure to send it. Please include your daytime
telephone number in case we need to contact you for further information.
UPS Surface (Brown Label) takes 5-6 days, Blue takes 2-3 days. Red is an overnight service and is
expensive. Send the PK-232 in a way that it can be traced if we cannot verify receipt of shipment.
We suggest UPS or insured postal shipment.
f the PK-232 is still under the original owner's warranty, Timewave will pay the cost of the return
shipment to you. The current policy is that it will be returned UPS Brown. f the owner wishes to
PK-232 to be returned Blue, Red or by other overnight service he must furnishes the return cost
for the method he selects.
f the PK-232 is out of warranty, it will be returned by UPS Brown COD unless:
1) t was received UPS Blue/Red in which case it will go back UPS Blue COD, or
2) f you designate billing to V SA or MASTERCARD or American Express, or
3) you prepay the service charges with a personal check, or
4) you specify some other method of return.
Typically, we will service the product in five to ten working days after it has arrived at Timewave if
we have all the facts. f we must call you, it may take longer. PLEASE include a letter stating the
problem and where you can be reached by telephone. f you can be reached by phone in the eve-
ning on the East Coast, let us know the number. Our current rate for non-warranty service of the
PK-232 is a flat rate of $75 which includes return shipping. Timewave is not responsible for dam-
age such as caused by lightning, nonprofessional alterations, poor storage/handling, etc. We will
make note of any shipping damage upon receipt. See the inside back cover for Warranty informa-
tion.
Should your warranty card not be on file at Timewave, you need to send the proof of purchase
date to receive warranty service. Typically a copy of your bill of sale from an Timewave dealer will
suffice.
