TPA-AA-202 Accessory Cable Kit Installation Instructions

Caution: The radio produces a specific audio level at the
maximum rated power. It is the sole responsibility of the end-
user to ensure applicability and compliance with the relevant
legal regulations defining the noise level an individual can be
subjected to.
Introduction
The TPA-AA-202 accessory cable kit is used
to connect external third-party accessories,
such as speaker microphones and headsets,
to the accessory connector at the rear of the
radio.
Connecting an Accessory
1. Verify that your accessory is compatible
with the accessory connector, refer to
Table 1.1.
2. When connecting an accessory, make
sure it meets the following specifications:
■speaker impedance: 32Ω (16Ω
min.)
■speaker power: 0.25Wrms (min.)
■microphone: electret, approximately 1kΩ
■PTT switch: not in series with microphone.
Note: If your accessory has a PTT switch in series with the microphone,
the accessory cannot be used. The PTT needs to be a separate signal and
must be made available at the connector separately; it must not be
multiplexed on any other signal.
3. Disassemble the kit as described in “Disassembly and Reassembly” on page 3.
4. Solder the wires of the accessory cable kit to the interface of your accessory (refer
to Table 1.1 on page 2).
5. Modify the components on the accessory connector PCB as follows (refer to Fig-
ure 1.2). Note that some components may already be fitted by default.
■For all accessories with differential speaker (not referenced to ground), fit a
0Ω link (1206) at position C1.
■For all accessories with a single-ended speaker (referenced to ground), fit a
4.7µF capacitor (ceramic, 1206, X7R, 16V) at position C1 instead of the
fitted 0Ω link (1206).

■To disable the radio’s internal speaker, fit a 0Ω link (0603) at position R3.
■When using an external switch to control the ACC PTT line, for example in
a hands-free vehicle kit, fit a 0Ω (0603) link at position R4.
■To enable an external function button, fit a 12kΩ resistor (0603, 1/
10W±5%) at position R1.
Reassemble the kit as described in “Disassembly and Reassembly” on page 3.

Disassembly and Reassembly
1. Use a Torx T6 screwdriver to remove the screw B, and remove the accessory
housing seal C, and the accessory seal plate D.
2. Fold out the accessory connector PCB E.
Important: During reassembly, make sure that the accessory housing
seal C is inserted correctly inside the accessory connector housing F.
Reassembly is carried out in reverse order of the disassembly.
