Care and Maintenance
: Your RT-11 tuner is essentially maintenance-free, and rugged enough for
normal outdoor use. The outer case may be cleaned as needed with a soft cloth slightly dampened
in household cleaning solution. As with any modern electronic device, the RT-11 can be damaged
by temperature extremes, water, impact or static discharge.
Technical Support:
We are happy to help you with your RT-11. Telephone technical support is
available at 410-586-2177 weekdays from 9 am to 5pm Eastern time. Inquiries by Fax at 410-586-
8475 are welcome, and prompt e-mail support is available at ldg@ldgelectronics.com.
Warranty and Service
: Factory assembled units are warranted against defects in parts or
workmanship for one year from purchase. Kits are warranted against defects in parts only for one
year from purchase. This warranty applies to the original purchaser only; it is not transferable. A
copy of the receipt showing the purchaser’s name and the date of purchase must accompany units
returned for warranty service. All returns must be shipped to us pre-paid; we will not accept units
with postage due. A return form is provided on our web site for your convenience.
If you need to return your RT-11 to us for service, package it carefully, keeping in mind that we will
re-use your packaging to return the unit to you. Include a full description of the problem, along with
your name, address and a phone number or e-mail address where we can reach you with any
questions. Repair turnaround time can vary from 2 to 6 weeks.
We will be glad to service your RT-11 after the warranty period. We will notify you of repair charges
by phone or e-mail, and bill you after repairs are completed.
Firmware upgrades:
From time to time we will release upgraded firmware for the RT-11, refining
operation and adding features. Your RT-11 is not field programmable; you will have to remove the
present chip and replace it with the upgrade chip. To remove the chip (68HC11, U1) you will need
an appropriate tool.
A PLCC extraction tool is ideal, but if you don’t have one you can fashion a substitute from an
ordinary paperclip. Straighten the paper clip, and then bend it into a “U” shape. Use pliers to bend
the last 1/8” of each end toward the center (see illustration).
