Table of Contents
The AP IR Remote Control System is designed to allow easy operation of all your
Audio Perfect®products from your desk or conference table, rather than from the
front panel of your ClearOne audio conferencing products.
The AP IR Remote Control is made up of two components: the handheld
infrared transmitter (remote control) and the base station infrared receiver. The
remote control is used to operate or customize the many features of the AP system,
such as: connect, disconnect, dial a telephone number, redial, store speed dial num-
bers, activate speed dial, hook flash, adjust volume, and mute the microphones.
The AP IR Remote functions with an AP400 stand-alone system, an
AP400/AP800 combination, an AP800/AP10 combination, or a GT1524. The
remote’s default programming may be easily customized to fit your needs by simply
pressing certain key sequences on the remote control unit. In the event of a power
outage, the new programming will be stored in the receiver’s memory and will not
be lost or altered. The remote also provides positive feedback for the Mute and In
Use LEDs by actively monitoring the response of the controlled unit(s) and indicat-
ing the correct status of each function.

Programmable Functions
Your AP IR Remote Control System is designed to operate right out of the box;
however, it is easy to program should you require different specifications. Select
from the options below and follow the instructions for the desired function you want
to customize.
The AP IR Remote does not use flow control. If a connected AP800, AP400, or
GT1524 has flow control enabled, the AP IR Remote will not operate. Disable flow
control on all connected devices.
Baud Rate
In order for you AP IR Remote Control System to operate properly, the baud rate
for the AP IR receiver and for the connected AP or GT1524 unit must be the same.
To program baud rate
1. Press and hold the Program button until the LEDs in the receiver flash.
2. Enter the code for the desired baud rate.
• 22831 = 9,600bps (default)
• 22832 = 19,200bps
• 22833 = 38,400bps
Baud rate example
To change the baud rate of the receiver to 19,200bps, enter:
Telephone Device Type and ID
The default dial command begins with ** which dials any AP telephone device. If
more than one telephone device (AP400 or AP10) is connected to the system, you
need to program the AP IR Remote with the device type and ID number of the unit
it will use for dialing and answering calls.
If there is only one telephone device in your network, or if you are using a sin-
gle unit, you do not need to program the AP IR Remote with the device type and
ID—the default programming will work.
The GT1524 is a stand-alone unit which has no device ID. If you are using this unit,
you do not need to program the telephone device type and ID.

Mute
The default mute command on the AP IR Remote will mute all mic inputs on all
device types and all device IDs. To change this command and to add new commands,
you will need to program the mute function. The AP IR Remote allows you program
up to 10 mute commands which are stored in locations 0–9. The default setting cur-
rently stores one mute command in location 0. All stored commands are executed
when the Mute On or Mute Off button is pressed.
The Mute LED on the AP IR Receiver lights to indicate that the programmed
channels have been muted. Please note that the AP IR Receiver references only the
channel programmed in location 0 to determine whether to illuminate the LED. If
location 0 is muted, the LED illuminates.
The GT1524 uses the default programming which mutes only the line and mic inputs.
To program mute commands
1. Press and hold the Program button until the
LEDs in the receiver flash.
2. Press the Mute On button.
3. Select mute command location (0-9).
4. Select the device type (0=device connected

devices).
5. Select the device ID (0–7, *=all units).
6. Select channel for muting (*, 01–08,
