wires are routed neatly, and that none will be pinched or fouled when you replace the case covers.
Step 12: Replace the bottom case cover. Reattach the speaker connector, being careful to observe
connector orientation. Replace the top case cover.
Congratulations! You have completed installation of your JT-11 automatic tuner. Proceed to
Operation.
Upgrading other Internal Tuners
If your radio already has an internal autotuner in it, you may be able to upgrade or replace it. If it
is an LDG tuner V3.5, you can simply purchase a new processor to get the upgraded features (see
our web site for purchasing information). If you have an LDG tuner with a version number lower
than V3.5 (or any other brand tuner), the tuner will need to be replaced.
To replace the tuner follow the installation instructions in reverse to remove the old tuner, then
follow the instructions for normal installation.
