A Word About Tuning Etiquette
Be sure to use a vacant frequency to tune. With today’s crowded ham bands, this is often difficult.
However, do your best to avoid interfering with other hams as you tune. Your AT-7000’s very
short tuning cycle, often only a fraction of a second, minimizes the impact of your tuning
transmissions.
Care and Maintenance
Your AT-7000 tuner is essentially maintenance-free; just be sure to observe the power limits
discussed in this manual. The outer case may be cleaned as needed with a soft cloth slightly
dampened in household cleaning solution. As with any modern electronic device, your AT-7000
can be damaged by temperature extremes, water, impact or static discharge. LDG strongly
recommends that you use a good quality, properly installed lightning arrestor in the antenna lead.

Warranty and Service
Your AT-7000 is warranted against defects in parts or workmanship for two years from purchase.
The warranty does not cover damage due to abuse or exceeding specifications. 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.
If you need to return your AT-7000 to us for service, package it carefully, keeping in mind that
we will re-use your packaging to return the unit to you. Download the return form from our web
site (www.ldgelectronics.com), fill it out and return it with your tuner. A self-addressed return-
shipping label, while not required, will help insure speedy and accurate delivery of your repaired
unit. 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. Repairs average about 3 to
6 weeks.
We will be glad to service your AT-7000 after the warranty period has ended. 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 LDG may release upgraded firmware for the AT-7000, refining operation and
adding features. Your AT-7000 is not field programmable; you will have to remove the present
chip and replace it with the upgrade chip. Upgrades are expected to cost about $10 - $20, and will
be announced on our web site when available.
