Setup
To begin using your remote speaker microphone, follow these simple steps:
- Ensure Radio is Off: Before connecting any accessories, make sure your Motorola TALKABOUT radio is powered off.
- Locate Audio Jack: Identify the 2.5mm single pin audio jack on your radio. This is typically located on the side or top of the radio.
- Connect Microphone: Insert the 2.5mm single pin connector of the remote speaker microphone firmly into the radio's audio jack until it clicks into place.
- Secure Microphone: Use the integrated clip on the back of the microphone to attach it securely to your lapel, collar, or other convenient clothing item. This positions the microphone close to your mouth for clear voice pickup and the speaker near your ear for optimal listening.
- Power On Radio: Once connected, you can power on your Motorola TALKABOUT radio.
Operating Instructions
The Motorola 53724 Remote Speaker Microphone offers convenient communication methods:
- Voice Activated Transmission (VOX): If your Motorola TALKABOUT radio supports VOX and this feature is enabled in your radio's settings, you can transmit simply by speaking into the microphone. The radio will automatically detect your voice and begin transmitting. Ensure your radio's VOX sensitivity is set appropriately for your environment.
- Push-to-Talk (PTT): For radios without VOX, or when you prefer manual control over transmissions, use the Push-to-Talk button located on the side of the microphone. Press and hold this button firmly while speaking to transmit. Release the button to stop transmitting and listen for incoming messages.
- Listening: All incoming audio from your radio will be routed through the speaker on the remote microphone. Adjust your radio's volume control for comfortable listening.
Maintenance and Care
Proper care will extend the life and performance of your remote speaker microphone:
- Cleaning: Gently wipe the microphone and its coiled cable with a soft, slightly damp cloth. Do not use harsh chemicals, solvents, or abrasive cleaners, as these can damage the plastic and electronic components. Ensure the connector is completely dry before plugging it back into your radio.
- Storage: Store the microphone in a cool, dry place away from direct sunlight, extreme temperatures, and excessive humidity. Avoid tightly coiling the cable, which can lead to internal wire damage over time.
- Handling: Always grasp the connector itself when plugging or unplugging the microphone from your radio. Avoid pulling on the cable, as this can strain the connection points and cause damage.
Troubleshooting
If you experience issues with your Motorola 53724 Remote Speaker Microphone, consider the following:
No Audio from Microphone Speaker:
- Check Connection: Ensure the 2.5mm connector is fully and securely inserted into your radio's audio jack.
- Radio Volume: Verify that your radio's volume is turned up to an audible level.
- Test Radio Speaker: Disconnect the microphone and test if your radio's internal speaker produces sound. This helps determine if the issue is with the radio or the microphone.
Microphone Not Transmitting:
- Compatibility: Confirm that your radio model is listed as compatible with the 53724 microphone (e.g., T200, T400, T600, T800, T8500/9500/EM1000 Series).
- VOX Settings: If using VOX, ensure it is enabled in your radio's settings and that the sensitivity is adjusted correctly. Speak clearly and loudly enough for VOX to activate.
- PTT Button: If using Push-to-Talk, ensure you are pressing and holding the PTT button firmly while speaking.
- Radio Power/Battery: Check that your radio is powered on and has sufficient battery charge.
If these steps do not resolve the issue, please refer to your radio's specific user manual or contact Motorola Solutions customer support for further assistance.
