Motorola ASTRO Digital Spectra, Instruction Manual

Theory of Operation: Power-Up
32 6881086C22-B
Power-Up
The ON/OFF power button located on the ASTRO Spectra/Spectra Plus
control head is disabled before shipment. Therefore, the station is immediately
operational when its power cord is plugged into a live AC outlet. To enable the
ON/OFF power button on the control head, refer to the information in “DIP
Switch and Jumper Settings” on page 8 of this manual. Please note that the
ON/OFF power button on the control head controls the power to the control
head only. For W9 model Consolettes (Digital Remote Control), no control
head is present and the station will become immediately operational when its
power cord is plugged into a live AC outlet.
Once the station is powered, the Power On LED should light up, and the station
should be ready to receive or transmit.
Receive
Since there can be various configurations of the Consolette depending upon
the user's requirements, no detailed receive operating instructions will be given
in this section. However, detailed operating instructions can be found in the
ASTRO Spectra/Spectra Plus radio user’s guide. For information regarding
remote control deskset operation, refer to the applicable instruction manual.
Transmit
Since there can be various configurations of the Consolette depending upon
the user's requirements, no detailed transmit operating instructions will be
given in this section. However, detailed operating instructions can be found in
the ASTRO Spectra/Spectra Plus radio user’s guide. For information regarding
the operation of the digital remote deskset, refer to the applicable instruction
manual.
NOTE: Each Consolette is shipped with the Emergency (Emer)
button disabled. Use the current version of the ASTRO CPS
to enable the Emergency button, if desired.
Power-Up Self-Check
Errors
Each time the radio is turned on, the MCU and DSP perform some internal
diagnostics. These diagnostics consist of checking the programmable devices
such as the FLASH ROMs, internal and external EEPROMs, SRAM devices,
and ADSIC configuration bus checksum. At the end of the power-up self-check
routines, if an error exists, the appropriate error code is shown on the display.
Self-test errors are classified as either “fatal” or “non-fatal.” Fatal errors will
inhibit user operation; non-fatal errors will not. For non-display radios, the error
codes may be read using the Customer Programming Software (CPS) from the
universal connector at the rear of the ASTRO Spectra or Spectra Plus
Transceiver.
Do not connect anything to Accessory Connector 1
other than the supported ACIM connection.
Damage could occur to the Consolette and
unsupported external devices.
