    Basic Maintenance Handling Complementary metal-oxide semiconductor (CMOS) devices, and other high- technology devices, are used in this family of radios. While these devices have Precautions many attributes, their characteristics make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges. Damage can be latent, resulting in failures occurring weeks or months later.

    Basic Theory of Operation General The ASTRO Digital XTS 2500 / XTS 2250 / XTS 1500 radio and the MT 1500 / PR 1500 radio are wideband, synthesized, fixed-tuned radios available in the VHF Overview band. The XTS 2500 / XTS 2250 / XTS 1500 radios are capable of both analog operation (12.5 kHz or 25 kHz bandwidths) and digital ASTRO mode operation (12.5 kHz only).

The VCO buffer, actually generates the first LO and transmit-injection signals and buffers them to the required power level. The synthesizer/prescaler circuit module incorporates frequency-division and comparison circuitry to keep the VCO signals stable. The synthesizer/prescaler IC is controlled by the microcontrol unit through a serial bus.
