Page 88: Power-Up Self-Check Errors
Troubleshooting Procedures: Power-Up Self-Check Errors Power-Up Self-Check Errors Each time the radio is turned on, the MCU and DSP perform a series of internal diagnostics. These diagnostics consist of checking such programmable devices as the FLASH ROMs, the EEPROM, and SRAM devices. Problems detected during the power-up self-check routines are presented as error codes on the radio’s display.

Page 459: Glossary
Glossary Glossary This glossary contains an alphabetical listing of terms and their definitions that are applicable to ASTRO portable and mobile subscriber radio products. All terms do not necessarily apply to all radios, and some terms are merely generic in nature. Term Definition See analog-to-digital conversion.
Page 460 Glossary-2 Glossary Term Definition codeplug Firmware that contains the unique personality for a system or device. A codeplug is programmable and allows changes to system and unit parameters. See also firmware. coder/decoder A device that encodes or decodes a signal. See Customer Programming Software.
Page 461 FLASHcodes are only applicable for radios which are upgradeable through the FLASHport process. FLASHport A Motorola term that describes the ability of a radio to change memory. Every FLASHport radio contains a FLASHport EEPROM memory chip that can be software written and rewritten to, again and again.
Page 462 Glossary-4 Glossary Term Definition Global Control A mixed-signal (analog and digital) integrated circuit that provides Audio and Power IC control, audio, and voltage regulation functionality for the Controller board. GPIO See General-Purpose Input/Output. host code Object code executed by the host processor in an ASTRO subscriber radio.
Page 463 Data transmitted on the control channel from the central controller to the word subscriber unit. over-molded pad- A Motorola custom IC package, distinguished by the presence of solder array carrier balls on the bottom pads. over-the-air rekeying Allows the dispatcher to remotely reprogram the encryption keys in the radio.
Page 464 Glossary-6 Glossary Term Definition phase-locked loop A circuit in which an oscillator is kept in phase with a reference, usually after passing through a frequency divider. See private-line tone squelch. See phase-locked loop. Power Control IC The power control IC is intended for closed-loop bias control of power amplifiers.
Page 465 Glossary Glossary-7 Term Definition repeater/talkaround A conventional radio feature that permits communication through a receive/transmit facility, which re-transmits received signals in order to improve communication range and coverage. RESET Reset line: an input to the microcontroller that restarts execution. See radio frequency. RF PA See radio frequency power amplifier.
Page 466 Glossary-8 Glossary Term Definition SRAM See static RAM. See Synchronous Serial Interface. Standby mode An operating mode in which the radio is muted but still continues to monitor data. static RAM A type of memory used for volatile, program/data memory that does not need to be refreshed.
Page 467 Glossary Glossary-9 Term Definition vector sum excited A voice-encoding technique used in ASTRO digital voice. linear predictive coding Very-High Frequency. Vehicle Interface Port. vocoder An electronic device for synthesizing speech by implementing a compression algorithm particular to voice. See also voice encoder. vocoder/controller A PC board that contains an ASTRO radio’s microcontroller, DSP, memory, audio and power functions, and interface support circuitry.
