SECTION 2 – INSTALLATION
2.1 Introduction
This section contains unpacking and inspection procedures, installation information, and post-installation checks.
2.2 Continued Airworthiness
Maintenance of the JA23-001 is on condition only. Scheduled inspection and/or periodic maintenance of this unit is
not required.
2.3 Unpacking and Inspecting Equipment
Unpack the equipment carefully. Check for shipping damage and report any problems to the relevant carrier. Confirm
that the Authorized Release Certificate or Certificate of Conformance is included. Complete the on-line warranty card
from the Jupiter Avionics Corporation (JAC) website - www.jupiteravionics.com/warrantyregistration
2.3.1 Warranty
This product manufactured by JAC is warranted to be free of defects in workmanship or performance for 2 years from
the date of installation by an approved JAC dealer or agency. This warranty covers the cost of all materials and labour
to repair or replace the unit, but does not include the cost of transporting the defective unit to and from JAC or its
designated warranty repair centre, or of removing and replacing the defective unit in the aircraft. This warranty does
not cover failures due to abuse, misuse, accident, or unauthorized alteration or repairs.
THIS WARRANTY IS VOID IF THE PRODUCT IS NOT INSTALLED BY AN AUTHORIZED JAC DEALER. If the on-
line warranty card is not completed, the product will be warranted from the date of manufacture.
Contact JAC for return authorization, and for any questions regarding this warranty and how it applies to your unit(s).
JAC is the final arbiter concerning warranty issues.
2.4 Installation Procedures
WARNING: Loud noise can cause hearing damage. Set the headset volume to minimum before
conducting tests, and slowly increase the volume to a comfortable listening level.
CAUTION: The power input circuitry of the unit may be damaged if the installation does not conform to the
wiring instructions in this manual.
2.4.1 Installation Limitations
Those installing the JA23, on or in a specific type or class of aircraft, must determine that the aircraft installation
conditions meet standards. The JA23 may be installed only by following the applicable airworthiness requirements.
2.4.2 Cabling and Wiring
All wire shall be selected in accordance with the original aircraft manufacturer’s maintenance instructions, or AC43.13-
1B Change 1, Paragraphs 11-76 through 11-78. Unshielded wire types shall qualify to MIL-W-22759 as specified in
AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. For shielded wire applications, use Tefzel
MIL-C-27500 shielded wire with tag ring or equivalent (for shield terminations) to make the most compact and easily
terminated interconnect. Follow the Connector Map in Appendix A of this manual.

Installation and Operating Manual
Rev A Page 5
Allow 3” from the end of the shielded wiring to the shield termination to allow the connector hood to be easily installed.
Refer to the Interconnect drawing in Appendix A of this manual for shield termination details. Note that this unit has a
‘clamshell’ hood that is installed after the wiring is complete.
Maintain wire segregation and route wiring in accordance with the original aircraft manufacturer’s maintenance
instructions.
Unless otherwise noted, all wiring shall be a minimum of 24 AWG, except power and ground lines, which shall be a
minimum of 22 AWG. Refer to the Interconnect drawing for additional specifications. Check that the ground
connection is clean and well secured, and that it shares no path with any electrically noisy aircraft accessories such
as blowers, turn-and-bank instruments, or similar loads.
2.4.3 Mechanical Installation
The JA23-001 can be mounted in any attitude and location with sufficient clearance for the connector and wiring
harness. It requires no direct cooling.
2.4.4 Post Installation Checks
2.4.4.1 Voltage/Resistance checks.
Do not attach this unit until the following conditions are met:
a) Check P1 pin 1for +28 Vdc relative to ground.
b) Check P1 pin 9for continuity to ground (less than 0.5 Ω).
c) Check P1 pins 6 and 14 for continuity to ground (less than 0.5 Ω) when relevant switch is closed (if
connected).
d) Check all pins for shorts to ground or adjacent pins.
2.4.4.2 Configuration
There are no configurable settings on the JA23-001.
2.4.4.3 Power on Checks.
Power up the aircraft’s systems and confirm normal operation of allfunctions of the JA23. Refer to section 2.5 and
section 3.2 for alloperating functions.
When all performance checks are satisfied, complete the necessary regulatory documentation before releasing the
aircraft for service. Refer toAppendix B.
2.5 Equipment Function
When the SPEAKER PTT input is active, the sum of the SPEAKER INPUTS and SPEAKER MIC is routed to the
SPEAKER OUTPUT.
When the SPEAKER LEVEL AND MUTE HI input is grounded, the SPEAKER OUTPUT is muted.
When the SPEAKER LEVEL AND MUTE HI input is connected to the SPEAKER LEVEL AND MUTE LO via an
external control, the SPEAKER OUTPUT level is adjusted by the external speaker level control.
