In critical situations, users at the authorities and organisations with security tasks must be able to rely fully on their communication devices. Organisations such as the police, fire brigade and rescue services must be able to assure their employees of the best possible safety and reliability. The 2303 Stabilock delivers the measurement results quickly and precisely. Whether in trunked radio mode or optional direct mode, whether 400 or 800 MHz band: after setting the network parameters and the frequency range, the measuring device is ready for use. The 6.5-inch diagonal TFT colour display is divided into four areas from which the measurement results can be read numerically or graphically. All settings and measurement callups can be carried out via six soft keys or one-handed via the rotary and push button. Reduction of the TETRA complexity to what is really needed in the service – with this operating concept you can operate the measuring instrument easily via the high-quality click keyboard of the Stabilock. Alternatively, you can also access all the elements on the screen, like a PC, using a USB mouse.
