Note on this Manual
This manual assumes that the user already knows how to
perform a hearing test. Therefore, these instructions describe
the operations required to present various tones, masking, and
speech sounds using the Colt Audiometer, but do not contain
all of the steps needed to obtain the patient’s actual threshold
levels and other audiometric information.

Frye Electronics FONIX COLT Audiometer 1
Chapter 1: Introduction
1.1 Description
The Colt Audiometer is a clinical audiometer that is controlled with the touch-based interface
of an Android tablet. It includes air, bone, and speech audiometry as standard features. The
user interface is intuitive and elegant, allowing the operator to move between pure-tone and
speech testing with a simple touch.
Each Colt Audiometer is supplied with a monitor headset/boom microphone combination
that allows the clinician to monitor the signals the patient is hearing. When the talkback
microphone accessory is used, the clinician can also hear responses from a patient tested in a
sound booth.
Accessories for the Colt include sound eld speakers, a talkback microphone, a patient
response switch, and a soft carrying case. Please see Sections 1.7 and 1.8 for a list of available
accessories.
An of 2015, an option is available to add tactile controls over stimulus frequency, level and
presentation without having to look at the tablet, thus allowing continued observation of
the tested patient. The controls consist of knobs for adjustment of level and push buttons for
stimulus presentation. The single center knob is used to control frequency. It should be noted
that all touch screen functions continue to be active as well as the mechanical controls when
the tactile option is present.
A dual speech talk forward microphone option has also been made available. The audiometer
circuits have been upgraded to allow an easy installation. See section 2.1, sub section 9 for
installation and use details.
Note: A technical description, maintenance, specications and calibration information for
the Colt audiometer can be found in the Colt Maintenance Manual. The Colt Maintenance
Manual is available for download in the Manual section of the Frye website, www.frye.com.
Hard copies are also available from Frye Electronics.
Android tablet note:

These tablets, like computers, are not made by Frye Electronics, Inc., and may differ slightly,
one from another. The operation of the tablet supplied with the individual Colt audiometer
may thus be different from that described in this manual. All tablets provided with Colt
audiometers are tested for proper operation. If an operation problem occurs, please do not
hesitate to write or call the factory (See section 1.4 below).

The allowable leakage currents of IEC 60601-1 must not be exceeded. IEC 60601-1 should be
consulted when assembling such a system.
Warning: The Colt should not be connected to a multiple socket outlet with other equipment.
The USB connector should only be connected to a standard Computer USB port.
Electromagnetic compatibility
The Colt Audiometer complies with IEC 60601-1-2.
The Colt Audiometer generates and uses radio frequency energy. In some cases the device
could cause interference to radio or television reception. You can determine if the Colt Audi-
ometer is the source of such interference by turning the unit off and on.
If you are experiencing interference caused by the Colt Audiometer, you may be able to cor-
rect it by one or more of the following measures:
1. Relocate or reorient the receiving antenna.
2. Increase the distance between the Colt Audiometer and the receiver.
3. Connect the Colt Audiometer to a different outlet than the receiver.
In some cases radio transmitting devices, such as cellular telephones, may cause interference
to the Colt Audiometer. In this case try increasing the distance between the transmitter and
the Colt Audiometer.

EC REP

Frye Electronics FONIX COLT Audiometer 5
Wipe the Colt Audiometer case with a slightly moist cloth. Use plain water or water with
mild dishwashing detergent. Wipe away any detergent with a clean cloth moistened with
water, then dry the Colt Audiometer. Avoid solvents and abrasives; they can cause permanent
damage to the Colt Audiometer.
Never allow uid to enter:
• the electronics module
• the Android tablet
• the electrical connectors
Cleaning the earphones:
Although the danger of spreading disease through the audiometric earphones is low, it is not
non-existent. The manufacturer of the ear cushions recommends the use of any OSHA (Occu-
pation Safety and Health Agency) recommended anti-bacterial soap. Disposable acoustically
transparent covers are also available commercially. Insert earphone ear tips are single use
only and cannot be cleaned.

Chapter 2: Setup
This chapter describes how to set up the Colt Audiometer for testing.
2.1 Connecting the Colt Audiometer for Testing
1. Screw the Bluetooth antenna into the ANT connector on the Colt back panel.
2. Plug the TDH headphones into the back panel of the Colt Audiometer Base. The red
plug goes into the jack marked "PHONE RIGHT"; the blue plug goes into the jack
marked "PHONE LEFT." (TDH and Dual Cal only)
3. Plug the ER3 headphones into the Colt Audiometer Base. The red plug goes into the
jack marked "INSERT RIGHT"; the blue plug goes into the jack marked "INSERT
LEFT." (ER3 and Dual Cal only)
4. Plug the patient response switch (optional accessory) into the "PAT RESP" jack.
5. Plug the bone vibrator cord into the jack marked "BONE."
6. Plug the shielded sound eld speakers (optional accessories) into the jacks marked
"SPKR LEFT" and "SPKR RIGHT." Please note that both the speakers and the cables
should be purchased from Frye Electronics.
7. Plug the talkback microphone (optional accessory) into the jack marked "TALK
BACK MIC."
8. Plug the 3.5 mm cable into the headphone jack of the Android tablet. Plug the other
end of the cable into the “EXT INPUT” jack on the back panel of the Colt Audiometer
Base. This is necessary for performing speech testing using the built-in audio les on
the Android tablet. This jack on the Colt Audiometer Base is also used for any exter-
nal CD or MP3 player.
9. If the dual microphone option is used, plug the cable from this option into the "TALK
FWD MIC" jack. This cable connects to the side mounted right and left microphone
connector boxes and leads the signals to the stereo input circuit built into the talk
forward microphone jack."

12 Chapter 2: Setup
10. Plug in an external amplier (if desired) into the jacks labeled "LINE OUT LEFT" and
"LINE OUT RIGHT."
11. Connection to an external computer is done by plugging in a USB cable between the
Colt rear panel USB connector and the USB connector on the computer. After audio-
metric tests have been run, test data may be retrieved from the tablet by use of a USB
cable between tablet and computer.
2.2 Powering Up the Colt Audiometer
The Colt Audiometer is composed of two main parts: The Android tablet containing the user
interface program (Figure 2.2A), and the Colt Audiometer Base (Figure 2.2B), which contains
the specialized electronics necessary for creating highly accurate test signals. For the Colt
Audiometer to work properly, it is essential that good communication be established between
these two components. The following instructions must be followed in order to properly
establish and maintain that essential communication link.
Figure 2.2A: The Android Tablet containing the user interface program of the Colt

Frye Electronics FONIX COLT Audiometer 13
Figure 2.2B: The Colt Audiometer Base containing the precise electronics needed for Audiometric
Testing.
Step 1- Power on Colt Audiometer Base
Plug the Colt Audiometer Base into a suitable source of AC power (100-240 VAC, 50-60 Hz) and
turn on the power switch. See Figure 2.2C.
