Consolette Installation Guidelines
RF Operational Characteristics
Your ASTRO® Spectra®Consolette and ASTRO Spectra Plus Consolette contain a digital mobile wireless two-way
radio. When the Consolette is ON, it receives and transmits radio frequency (RF) energy.
Product Safety and RF Exposure Compliance
Operational Cautions
•Because of danger of introducing additional hazards, do not install substitute parts or perform any unauthorized
modifications of equipment.
•DO NOT operate the transmitter of any Consolette unless all RF connectors are secure and all connectors are
properly terminated.
•All equipment must be properly grounded in accordance with Motorola Standards and Guideline for
Communications Sites “R56” 68P81089E50 and specified installation instructions for safe operation.
•Slots and openings in the Consolette housing are provided for ventilation. To ensure reliable operation of the
product and to protect if from overheating, these slots and openings must not be blocked or covered.
•Only an authorized technician familiar with the Consolette should service equipment.
Lightning and Surge Suppression
General
The installation of Transient Voltage Surge Suppression (TVSS) devices is a requirement for all communication sites
and is essential for all facilities where communication-related electronics and electrical equipment are in use. Surges
and transient power anomalies are potentially destructive electrical disturbances, the most damaging being over-
voltage occurrences and short duration over-voltage events. Sometimes referred to as “spikes,” high-energy
transient power anomalies can arise from inductive load switching of other events within the power system or
capacitive and inductive coupling from environmental events, such as nearby lightning activity. Environmental and
inductive power anomalies are wideband occurrences with a frequency range from close to DC to well into the RF
high frequency spectrum. It is critical that each point-of-entry (AC, telephone, LAN, signal/control, and RF) into the
equipment area be protected against these anomalies. This protection is essential to reduce the risk of personal
injury, physical equipment damage, and loss of operations (equipment downtime).
Recommendations
To protect your equipment from lightning and surge damage, do the following:
•Install these TVSS devices as described in Chapter 9, “Transient Voltage Surge Suppression,” of the Motorola
Standards and Guideline for Communications Sites “R56” 68P81089E50 manual.
•Ground all RF transmission lines from the antenna structure to the shelter or building as described in Chapter 6,
“External Grounding,” of the Motorola Standards and Guideline for Communications Sites “R56” 68P81089E50
manual. Upon entering the building, all RF transmission lines shall route through a coaxial RF-type TVSS (or
Surge Protection Device).
Before using this product, read the operating instructions
for safe usage contained in the Product Safety and RF
Exposure booklet enclosed with your radio (Motorola
Publication part number 6881095C99).

Consolette Installation Guidelines
Safe Handling of CMOS Integrated-Circuit Devices
Introduction
This section will aid you in troubleshooting a malfunctioning Consolette. It is intended to be detailed enough to
localize the malfunctioning circuit and isolate the defective component.
Handling Precautions
Complementary metal-oxide semiconductor (CMOS) devices and other high-technology devices are used in the
Consolette. While the attributes of these devices are many, 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. Therefore, special precautions must be
taken to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are
mandatory for this radio and are especially important in low humidity conditions. DO NOT attempt to disassemble
the radio without observing the following handling precautions.
1. Eliminate static generators (plastics, Styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back loose hanging
neckties.
3. Store and transport all static-sensitive devices in ESD-protective containers.
4. Disconnect all power from the unit before ESD-sensitive components are removed or inserted unless otherwise
noted.
5. Use a static-safeguarded workstation, which can be accomplished through the use of an antistatic kit (Motorola
part number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table mat and a
static-control floor mat.
6. Always wear a conductive wrist strap when servicing this equipment. The Motorola part number for a
replacement wrist strap that connects to the table mat is 42-80385A59.
Parts Replacement and Substitution
Special care should be taken to ensure that a suspected component is actually the one at fault. This special care
will eliminate unnecessary unsoldering and removal of parts, which could damage or weaken other components or
the printed circuit board (PCB) itself.
When damaged parts are replaced, identical parts should be used. If the identical replacement component is not
locally available,checkthe parts listfor the proper Motorola partnumber and orderthe component from the Radio
Products Services Division.
Before using this product, read the operating instructions
for safe usage contained in the Product Safety and RF
Exposure booklet enclosed with your radio (Motorola
Publication part number 6881095C99).
