Bose 311822 User Manual

IR / 2.4GHz RF Modular Transceiver

Installation manual (draft v3)

1. Description

This drawing describes an RF / IR remote control transceiver module PCB. The
module is part of a panel of PCB’s defined by PT311822 and associated drawings.

The module consists of 3 separate circuits :

1) A 2.4GHz RF transceiver IC and etch antenna for use with an RF remote

2) An IR remote control transmitter

3) An IR remote control receiver

There is also a pair of LED for indication purposes

2. Cautions:

This transceiver module is ONLY to be installed in Bose Corporation devices.

This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation

Changes or modifications not expressly approved by Bose Corporation could void the
user’s authority to operate the equipment.”

NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

− Reorient or relocate the receiving antenna.

− Increase the separation between the equipment and receiver.

− Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

− Consult the dealer or an experienced radio/TV technician for help.
