🚀 Quick Setup

1. Locate the external speaker jack on your radio -- typically labeled "EXT SP" or marked with a speaker icon on the back or side panel
2. Plug in the 3.5mm connector -- the right-angle plug seats flush against the radio body for a clean installation
3. Mount the speaker using the included bracket and hardware in a convenient location
4. Adjust your radio's volume -- the radio's built-in speaker will mute automatically when the external speaker is plugged in

⚠️ Important Notes

• NOT compatible with handheld radios (HTs) that use dual-pin Kenwood-style connectors, proprietary multi-pin HT accessory ports, or have a HEADPHONE output. Requires a standard single 3.5mm external SPEAKER jack.
• This is a passive speaker. It does not have a built-in amplifier -- it is powered by your radio's audio output stage.
• Do not exceed 5 watts. Driving the speaker beyond its rated power may cause distortion or damage.
• Audio is mono. Communications radios output mono audio, and this speaker is designed for mono communications use -- it is not a stereo or music speaker.
• Plugging in the external speaker will mute your radio's internal speaker. This is normal behavior for all radios with an external speaker jack.
