General Safety
Remember! . . . Safety
depends on you!!
Ground the instrument
The following general safety precautions must be observed during all
phases of operation, service, and repair of the equipment described in
this manual. Failure to comply with these precautions or with specific
warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the equipment. Motorola, Inc. assumes
no liability for the customer’s failure to comply with these requirements.
The safety precautions listed below represent warnings of certain dangers
of which we are aware. You, as the user of this product, should follow
these warnings and all other safety precautions necessary for the safe
operation of the equipment in your operating environment.
To minimize shock hazard, the equipment chassis and enclosure must be
connected to an electrical ground. If the equipment is supplied with a
three-conductor ac power cable, the power cable must be either plugged
into an approved three-contact electrical outlet or used with a
three-contact to two-contact adapter. The three-contact to two-contact
adapter must have the grounding wire (green) firmly connected to an
electrical ground (safety ground) at the power outlet. The power jack and
mating plug of the power cable must meet International Electrotechnical
Commission (IEC) safety standards.
Do not operate in an explosive
atmosphere
Keep away from live circuits
NOTE
Refer to Grounding Guideline for Cellular Radio
Installations – 68P81150E62.
Do not operate the equipment in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.
Operating personnel must:
S not remove equipment covers. Only Factory Authorized Service
Personnel or other qualified maintenance personnel may remove
equipment covers for internal subassembly, or component
replacement, or any internal adjustment.
S not replace components with power cable connected. Under certain
conditions, dangerous voltages may exist even with the power cable
removed.
S always disconnect power and discharge circuits before touching them.

General Safety – continued
Do not service or adjust alone
Use caution when exposing or
handling the CRT
Do not substitute parts or
modify equipment
Do not attempt internal service or adjustment, unless another person,
capable of rendering first aid and resuscitation, is present.
Breakage of the Cathode–Ray Tube (CRT) causes a high-velocity
scattering of glass fragments (implosion). To prevent CRT implosion,
avoid rough handling or jarring of the equipment. The CRT should be
handled only by qualified maintenance personnel, using approved safety
mask and gloves.
Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification of equipment.
Contact Motorola Warranty and Repair for service and repair to ensure
that safety features are maintained.
Dangerous procedure
warnings
Warnings, such as the example below, precede potentially dangerous
procedures throughout this manual. Instructions contained in the
warnings must be followed. You should also employ all other safety
precautions that you deem necessary for the operation of the equipment
in your operating environment.
WARNING
Dangerous voltages, capable of causing death, are present in this
equipment. Use extreme caution when handling, testing, and
adjusting.
This Read-me-first document describes a summary of changes between
the existing SC4812T 800MHz BTS and the SC4812T-MC
(Multicarrier) BTS. The SC4812T-MC is based on the existing
SC 4812T platform and employs similar hardware and architecture. The
differences between these products are briefly described and illustrated
below. This section is not intended to replace the SC4812T-MC manual
set. This information applies generally to both 800 MHz +27V and
–48V frames, although only +27V illustrations are shown.
Multicarrier provides the capability for all PAs in all quadrants to
provide trunked power across all sector/carriers. This differs from the
previous architecture in which PA modules within a quadrant provided
trunked power to only one carrier. Furthermore, in SC4812T-MC,
adjacent channels can be combined onto one antenna versus being
transmitted on separate antennas in SC4812T.
An overview of the BTS differences is illustrated in the following table
and in illustrations on the following pages (Figure 1-1 thru Figure 1-4).
