Overview
Table of Contents
The McIntosh TM1 AM/FM Tuner Module adds AM/FM
Broadcast Reception to the MX119, MX134 or MX135
A/V Control Centers; the MHT Series A/V System Controllers, C45 Audio Control Center and other McIntosh Components. It also adds functionality of a second Tuner to the
MR85 AM/FM T uner. Follow the instructions in this guide
for installing the TM1 into the MX119, MX134, MX135,
MHT Series, C45, MR85 and other McIntosh Components.
The TM1 Tuner Module is not a user installable product. It
must be installed by the T echnical Professionals at your
McIntosh Dealer.

Important Information
1. Caution: To prevent the risk of electric
shock, first remove the AC Power Cord
from the back of the MX119, MX134,
MX135, MHT Series, C45, MR85 or
other McIntosh Component before
removing the top cover.
2. Some of the semiconductor devices (CMOS
and NMOS) used in the TM1 Module,
MX119, MX134, MX135, MHT Series, C45,
MR85 and other McIntosh Components are
inherently sensitive to static electricity even
when connected in a circuit, and can be permanently
damaged by a static electricity discharge. When handling
the TM1 and working inside the MX119, MX134, MX135,
MHT Series, C45, MR85 or other McIntosh Components,
follow the procedures below to insure against static
electricity damage.
A. Make sure the MX119, MX134, MX135, MHT Series,
C45, MR85 or other McIntosh Components are
properly grounded.
B. Use an approved wrist strap that is grounded.
C. Remove the TM1 from the Anti-Static Bag and work
with it only after the above conditions have been met.
D. The RAA1 Remote AM Antenna contains the Tuned
AM RF Amplifier First Stage Circuitry and is
matched to the specific AM/FM Tuner Module.
3. Some of the Installation Instructions in this Dealer
Installation Guide are also used for other McIntosh
Components. To identify the appropriate Installation
Instructions, refer to the label located on the Connector
Cover metal plate inside the McIntosh Component.
During the installation process this cover is removed,
allowing for the AM and FM Antenna Connections.
