4.3 Field Programming Equipment
The ASTRO family of radios can be aligned and programmed in the field. This requires specific 
equipment and special instructions. For ASTRO Digital Spectra radios, refer to the applicable Radio 
Service Software User’s Guide for complete field programming information. For ASTRO Digital 
Spectra Plus radios, refer to the online help in the Customer Programming Software.
4.3.1 ASTRO Digital Spectra
The ASTRO Digital Spectra radios use an electrically erasable, programmable read-only memory 
(EEPROM) device to store information on frequencies, squelch codes, signaling codes, time-out 
timer durations, and other parameters.
The ASTRO Digital Spectra radios can be programmed in the field any number of times without 
removing the EEPROM from the radio. To program, an IBM
® or IBM PC-compatible computer is 
connected to the radio through the rear accessory connector. Once the computer is connected to the 
radio, the prompts provided by the software can be followed.Table 4-6.  Service Aids for ASTRO Digital Spectra Plus Board-Level Troubleshooting

The following items, available through the Customer Care and Services Division (except the 
computer), are required when programming ASTRO Digital Spectra Model radios.
4.3.1.1  ASTRO Digital Spectra W3 Smart RIB Issue
When flashing a Model W3 mobile radio, the smart RIB box tends to reset if the correct power-up 
sequence is not observed. To avoid this problem, you must power up the radio before you use the 
smart RIB box. You might damage the control head or the RIB box if you use a modified RIB box to 
flash Model W3 radios.
4.3.1.2  ASTRO Digital Spectra Remote W3 Y Cable
The remote Y cable required for high-power Model W3 radios cannot be used for programming. The 
accessory connector in this cable does not have the BUS+, BUS-, and BUSY lines.Table 4-8.  ASTRO Digital Spectra Field Programming Items

In mid-power radios, when this cable is used, programming must be done through the rear 
accessory connector.
4.3.2 ASTRO Digital Spectra Plus
The ASTRO Digital Spectra Plus radios use a flash memory device to store information on 
frequencies, squelch codes, signaling codes, time-out timer durations, and other parameters.
The ASTRO Digital Spectra Plus radios can be programmed in the field any number of times without 
removing the flash memory from the radio. To program, an IBM or IBM PC-compatible computer is 
connected to the radio through the front connector using the programming cable. Once the computer 
is connected to the radio, the prompts provided by the user-friendly software can be followed.
The following items, available through the Customer Care and Services Division (except the 
computer), are required when programming ASTRO Digital Spectra Plus radios.
4.3.2.1  ASTRO Digital Spectra Plus Model W3
For the ASTRO Digital Spectra Plus radio with a W3 control head, it is possible for the message 
FL01/90 to display while using the HKN6155 programming cable for tuner, CPS, or flash 
programming. Upon completion of the operation, a reset will clear the message. Powering on the 
radio before attaching the programming cable will decrease the occurrence of the 
FL01/90 
message.Table 4-9.  ASTRO Digital Spectra Plus Field Programming Items

							Chapter 5 Performance Checks
5.1 Introduction
This section covers performance checks used to verify that the radio meets published specifications. 
The recommended test equipment listed in the previous section approaches the accuracy of the 
manufacturing equipment, with a few exceptions. Accuracy of the equipment must be maintained in 
compliance with the manufacturer’s recommended calibration schedule.
5.2 Test Setup
The equipment required for performance checks is connected as shown in the following diagrams.

2. In RF test mode, press the Vo l u m e rocker to adjust the volume. The volume display for the 
ASTRO Digital Spectra will be in 256 increments, not the usual 16, while in the test mode. 
This allows for precise setting of rated audio, etc.
For the ASTRO Digital Spectra Plus, the volume is still displayed as a value between 0 to 15.
3. Press the Home button to move the cursor back and forth between the frequency and 
signaling type (See 
Table 5-2 on this page and Table 5-3 on page 5-5). The first digit will flash 
to indicate which type is currently selected. Press the Mode button to scroll through the 
available selections.
