Specifications: * Mounted with a solar battery: Automatically charging from the solar panel to the built-in nickel-cadmium battery. * Compatible with 3-bands including X, K, and new K bands: Not only the X-band, but the model CX-660 is also compatible with the K-band and the new K band so as to be compatible with various radar speed traps. * Provision with dual-mode reception sensitivity: Depending on the running condition, it is possible to switch receptive sensitivity via one-touch operation over to the normal mode while running through a city road at a low speed or over to the super mode for catching radar waves emitted from a far location while driving the vehicle at a high speed through a highway or an automobile exclusive road. * Provision with the Auto Alarm Cut (AAC) system: The built-in oscillation sensor shuts off unwanted alarming sound generated while halting the vehicle or driving it at a low speed. * Auto Power Off function: When non-oscillation condition lasts for about 3 minutes, the power supply source is automatically shut off until the sensor detects a next oscillation, thus saving unwanted consumption of the battery voltage. * Auto Dimming & Auto Muting function: Following the elapse of a predetermined period after receiving radar waves, brightness of the alarm level meter is attenuated via the auto-dimming function to cause the volume of alarming sound to be lowered via the auto-muting function.
