PRYME BT-511 BLUETOOTH ADAPTOR for Kenwood Radios:

Works with the Nexedge radios including the NX-200 and NX-300. The Kenwood multi-pin radios TK-2140, TK-2180, TK-3140, TK-3148, TK-3180, TK-5210, TK-5220, TK-5310, TK-5320, TK-5400 and more. NOTE: Some radios may require reprogramming or modification.

NOTE: The BT-511 is compatible only with Kenwood radios with 4-digit model numbers (example: TK-3180). Radios with 3-digit model numbers (example: TK-290) do not provide enough current to the accessory connector to power the Bluetooth Adapter. Some radios can be modified by a qualified technican to provide power by removing a current-limiting resistor.

IMPORTANT NOTE: For most newer Kenwood and Nexedge radios you must set the following option using the radio's computer programming software: Extended Function > Universal Connector Pin No. 11: HRS Adapter

For older Kenwood radios with 4-digit model numbers (example: TK-3180) that do not have the "HRS Adapter" option available, set the following instead: Extended Function > Universal Connector Pin No. 11: Always 5 V (high)

Some older Kenwood radios with 3-digit model numbers (example: TK-290 or TK-380) have a current-limiting resistor inside the radio. This resistor lowers the power available to accessory devices such as the PRYMEBLU Adapter. Some radios provide as little as 30 mA of current.

In order to provide enough power for the PRYMEBLU Adapter, these radios must be modified and the current-limiting resistor must be replaced with a resistor of a lowervalue, allowing more power to be available to the accessory port.

The PRYMEBLU Adapter requires approximately 80 mA of current at peak draw. Contact your local two-way radio dealer or PRYME technical support in regards to this modification. Modifying your two-way radio may void the warranty, even if the modification is done correctly. PRYME Radio Products is not responsible for any damage or loss which may occur. Modifications should be done by a trained two-way radio technician only.
