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 enduser 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 Figure 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). 402-00029-00 Page 1 Page 2 black gray GND ACC PTT 3V3 CMOS External speaker differential output External speaker differential output External press-to-talk input Analog ground External microphone input (electret) Dynamic microphones are not supported.

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.
