Motorola SL4000

Versatile and powerful, our revolutionary MOTOTRBO portable combines the best of two-way radio functionality with the latest digital technology. SL series radios integrate voice and data seamlessly, offer enhanced features that are easy to use, such as integrated Bluetooth®, covert mode, vibrate alert and Intelligent Audio. Designed in a small form factor so sophisticated, it is like no other radio you have used. Only the SL series enhances your professionalism, so you can remaster your productivity and image like never before.


Unquestionably, thin, small and lightweight were the top priorities in creating the SL Series radios. Our mechanical engineers knew how to keep the radio compact and details, such as the PC board, were skilfully designed by our architects to fit the lighter, smaller size.


Aside from shape, much of the SL Series hinges on how well it works. Our engineering teams ran multiple series of simulations and mock-ups on the antenna to make sure it optimized digital performance in the coverage area.


One of the key considerations was the large, high resolution screen. We chose a specialized, high-definition display that automatically adjusts backlighting to changes in light – from bright sunlight to dark night. This would provide outstanding clarity and a stunning colour display that was easy to read in any situation.


Audio quality had to be exceptional so hotel staff could hear loud and clear in the noisiest environments, from a crowded banquet to a bustling lobby. The radio had to have exceptional audio performance that fit inside a small package.


Finally, we performed a number of usability studies to make sure we optimised all aspects of the radio. Whether it was having users try the fullsize keypad, making the battery latch easy to open, or slimming down the battery pack to fit within the slim housing without sacrificing power. We also made the navigation menus, buttons and features easy to use.
