Page 20: Radio Description
Description available. One of the newest in a long line of quality Motorola products, the ASTRO Digital XTS 2500 radio provides improved voice quality across more coverage area. The digital process, called “embedded signalling,” intermixes system signalling information with digital voice, resulting in improved system reliability, and the capability of supporting a multitude of advanced features. -
Page 21: Basic Maintenance
Each of these topics provides information vital to the successful operation and maintenance This Section of your radio. Preventive ASTRO Digital XTS 2500 radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended. Maintenance Inspection Check that the external surfaces of the radio are clean, and that all external controls and switches are functional. -
Page 22: Handling Precautions
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 many attributes, their Precautions 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. -
Page 23: Basic Theory Of Operation
General The ASTRO Digital XTS 2500 radio is a wideband, synthesized, fixed-tuned radio available in the 700/800 MHz bands. All XTS 2500 radios are capable of both analog Overview operation (12.5 kHz or 25 kHz bandwidths) and digital ASTRO mode operation (12.5 kHz only). -
Page 24: Analog Mode Of Operation
Basic Theory of Operation Analog Mode of Operation Receiving When the radio is receiving (see Figure 2), the signal comes from the antenna connector to the radio board, passes through the RX/TX antenna switch and into the receiver front end. A 15dB step attenuator is included in the front end to provide additional protection against strong signals. -
