Remote Control Codes
The Remote Control included with the C49 utilizes the
NORMAL McIntosh Control Codes. The Second Set
of Control Codes the C49 will respond to is referred
to as the ALTERNATE Codes. The Alternate Codes
are used when the C49 is used in the same location as
another McIntosh Preamplifier and/or A/V Processor.
This will prevent the Remote Control from affect-
ing the operation of both units at the same time. To
activate the Remote Control ALTERNATE Codes
perform the following steps:
1. Press and hold in the INPUT Control to enter the
SETUP MODE. Refer to figure 2 on page 13.
2. Rotate the INPUT Control until "SETUP: IR
Codes, Normal" appears on the Information

Display. Refer to figure 42.

tions such as source selection, volume adjustment, etc)
or absence of an audio signal. If it is desirable to dis-
able the Auto Off Feature perform the following steps:
