Motorola RSN4005A Desktop Tray with Speaker | DM3000 & DM4000
Setting up a reliable local dispatch station doesn't have to be complicated. If you are looking to convert your vehicle-mounted mobile radio into a fixed desktop base station, the Motorola RSN4005A Mobile Desktop Tray is exactly what you need. Designed specifically for MOTOTRBO mobile radios, this tray provides a secure housing and enhances your setup with an integrated speaker for crystal-clear audio delivery.
Why should I choose the Motorola RSN4005A desktop tray?
This genuine Motorola accessory is engineered to offer simple and easy installation for local dispatching operations. Instead of relying solely on the radio's internal audio, the built-in speaker ensures that incoming transmissions are loud and clear, which is essential for busy control rooms, offices, or security desks. If you prefer a setup without the integrated audio, you might also consider the Motorola GLN7318A Desktop Tray Without Speaker.
Which mobile radios are compatible with this tray?
The RSN4005A is highly versatile and fits a wide range of MOTOTRBO digital mobile radios. It is fully compatible with the DM3000 series, including the DM3400, DM3401, DM3600, and DM3601. It also perfectly accommodates the DM4000 series, such as the DM4400, DM4401, DM4600, and the Motorola DM4601.
What else do I need to complete my base station setup?
While this desktop tray securely holds your radio and provides external audio, you will still need a reliable power source to run your mobile radio from a standard mains outlet. We highly recommend pairing this tray with the Motorola GPN6145B Power Supply Unit to ensure your dispatch station operates smoothly and continuously.
