SAFETY TRAINING INFORMATION
WARNING
The M/A-COM P7100PI portable radio
generates RF electromagnetic energ
y
during transmit mode. This radio is
designed for and classified as
“Occupational Use Only,” meaning it
must be used only during the course of employment
by individuals aware of the hazards and the ways to
minimize such hazards. This radio is NOT intended for
use by the “General Population” in an uncontrolled
environment.
The P7100PI portable radio has been tested and
complies with the FCC RF exposure limits for
“Occupational Use Only.” In addition, this M/A-COM radio
complies with the following Standards and Guidelines with
regard to RF energy and electromagnetic energy levels
and evaluation of such levels for exposure to humans:
· FCC OET Bulletin 65 Edition 97-01 Supplement C,
Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic
Fields.
· American National Standards Institute (C95.1 – 1992),
IEEE Standard for Safety Levels with Respect to
Human Exposure to Radio Frequency Electromagnetic
Fields, 3 kHz to 300 GHz.
· American National Standards Institute (C95.3 – 1992),
IEEE Recommended Practice for the Measurement of
4
Potentially Hazardous Electromagnetic Fields – RF
and Microwave.
CAUTION
To ensure that exposure to RF
electromagnetic energy is within the FCC
allowable limits for occupational use,
always adhere to the following
guidelines:
· DO NOT operate the radio without a proper antenna
attached, as this may damage the radio and may also
cause the FCC RF exposure limits to be exceeded. A
proper antenna is the antenna supplied with this radio
by M/A-COM or an antenna specifically authorized by
M/A-COM for use with this radio.
· DO NOT transmit for more than 50% of total radio use
time (“50% duty cycle”). Transmitting more than 50%
of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is
transmitting when the “TX” indicator appears in the
display. The radio will transmit by pressing the “PTT”
button.
· ALWAYS use M/A-COM authorized accessories
(antennas, batteries, belt clips, speaker/mics, etc).
Use of unauthorized accessories may cause the FCC
Occupational/Controlled Exposure RF compliance
requirements to be exceeded.
5
· ALWAYS keep the device and its antenna at least 2
cm (0.8 inches) from the body and at least 5 cm (2
inches) from the face when transmitting to ensure FCC
RF exposure compliance requirements are not
exceeded. This radio has been tested for RF exposure
compliance at the distances listed in Table 1.
However, to provide the recipients of your
transmission the best sound quality, hold the antenna
at least 5 cm (2 inches) from mouth, and slightly off to
one side.

The information listed above provides the information
needed to make the user aware of a RF exposure, and
what to do to assure that this radio operates within the FCC
RF exposure limits of this radio.
ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
During transmissions, this M/A-COM radio generates
RF energy that can possibly cause interference with other
devices or systems. To avoid such interference, turn off
6
the radio in areas where signs are posted to do so. DO
NOT operate the transmitter in areas that are sensitive to
electromagnetic radiation such as hospitals, aircraft, and
blasting sites.
7
OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in
accordance with the rules and regulations of the Federal
Communications Commission (FCC). As an operator of
two-way radio equipment, you must be thoroughly familiar
with the rules that apply to your particular type of radio
operation. Following these rules will help eliminate
confusion and will assure the most efficient use of existing
radio channels. This will provide a smooth operating radio
network.
When using the radio, remember these rules:
1. It is a violation of FCC rules to interrupt any distress or
emergency message. As the radio operates in much
the same way as a telephone "party line" when in
conventional mode, always listen and/or observe the
absence of the “busy” display (refer to Table 2 – Three
Line Display for display character) to make sure that
the line is clear before sending any messages. If
someone is sending an emergency message, such as
reporting a fire or asking for help in an accident, KEEP
OFF THE AIR! Emergency calls have priority over all
other messages.
2. Use of profane or obscene language is prohibited by
Federal Law.
3. It is against the law to send false call letters or a false
distress or emergency message.
8
4. The FCC requires that conversations be brief and
confined to business. To save time, use coded
messages whenever possible.
5. Using the radio to send personal messages (except in
an emergency) is a violation of FCC rules. Send only
those messages essential for the business operation.
6. It is against Federal Law to repeat or otherwise make
known anything overheard on the radio. Conversations
between others sharing your channel must be
regarded as confidential.
9
OPERATING TIPS
Antenna location and condition are important when
operating a portable radio. Operating the radio in low lying
areas or terrain, under power lines or bridges, inside of a
vehicle or in a metal or steel framed building can severely
reduce the range of the unit. Mountains can also reduce
the range of the unit.
In areas where transmission or reception is poor, some
improvement may be obtained by ensuring that the
antenna is vertical. Moving a few yards in another direction
or moving to a higher elevation may also improve
communications. Vehicular operation can be aided with the
use of an externally mounted antenna.
Battery condition is another important factor in the
trouble free operation of a portable radio. Always properly
charge the batteries.
EFFICIENT RADIO OPERATION
Hold the portable radio approximately three inches from
your mouth and speak into the microphone at a normal
voice level.
Keep the antenna in a vertical position when receiving
or transmitting a message.
Do not hold the antenna when receiving a message
and, especially, do not hold when transmitting a message.
10
WARNING
Do NOT hold onto the antenna when
transmitting.
Antenna Care and Replacement
WARNING
Always keep the antenna at least 0.8 inches
(2 cm.) away from the body and 2 inches (5
cm.) from the face when transmitting to
ensure FCC RF exposure compliance
requirements are not exceeded.
WARNING
Do not use the portable radio with a damaged
or missing antenna. A minor burn may result
if a damaged antenna comes into contact
with the skin. Replace a damaged antenna
immediately. A missing antenna could
damage your portable radio.
WARNING
Use only the supplied or approved antenna.
Unauthorized antennas, modifications or
attachments could damage the radio unit and
may violate FCC regulations.
11
Electronic Devices
CAUTION
RF energy from your portable radio may
affect some electronic equipment. Most
modern electronic equipment in cars,
hospitals, homes, etc. are shielded from RF
energy. However, in areas that instruct you to
turn off two-way radio equipment, always
observe the rules. If in doubt, turn it off!
Aircraft
WARNING
Always turn off your portable radio before
boarding any aircraft!
· Use it on the ground only with crew
permission.
· DO NOT use while in-flight!!
Blasting Areas
WARNING
To avoid interfering with blasting operations,
turn your radio OFF when in a "blasting area"
or in areas posted "turn off two-way radio."
Remote control RF devices are used by some
construction crews to set off explosives.
12
Potentially Explosive Atmospheres
WARNING
Areas with potentially explosive atmosphere
are often, but not always, clearly marked.
These may be fueling areas, such as gas
stations, fuel or chemical transfer or storage
facilities, and areas where the air contains
chemicals or particles, such as grain, dust or
metal powders.
Sparks in such areas could cause an
explosion or fire resulting in bodily injury or
even death.
Turn OFF your radio when in any area with a
potentially explosive atmosphere. It is rare,
but not impossible that the radio or its
accessories could generate sparks.
13
BATTERY DISPOSAL
The P7100IP portable radios use rechargeable,
recyclable Nickel Cadmium (NiCd) or Nickel Metal Hydride
(NiMH) batteries.
NICKEL CADMIUM BATTERY PACK DISPOSAL
At the end of its useful life, under
various state and local laws, it may
be illegal to dispose of the Nickel
Cadmium batteries into the
municipal waste stream. Check with
local solid waste officials for details
of recycling options or proper disposal. Call Toll Free 1-
800-8BATTERY for information and/or procedures for

It consists of the Reference Oscillator, PLL Frequency Synthesizer chip U305, Loop filter, Rx VCO Z303, and
Tx VCO Z304.
PLL Frequency Synthesizer chip receives PLL data, and control information from the microcomputer and from
this generates the Tx/Rx RF frequencies. It also provides frequency lock status to the microcomputer.
Rx VCO and Tx VCO are locked to the Reference Oscillator by a single direct-divide synthesis loop consisting
of the Feedback Buffer, Prescaler, and PLL Frequency Synthesizer chip.

The standard of reference oscillator frequency is 19.2MHz.
The TCXO is enclosed in a RF shielded can. The TCXO is compensated by internal temperature compensated
circuit for both low and high temperature. With no additional compensated the oscillator will provide 1.5 PPM

3-2 Fractional-N Frequency Synthesizer chip
Fractional-N Frequency synthesizer chip U305 provides fractionality through the use of main ∆Σ modulators.
The output from the modulators are combined with the main and auxiliary divider ratios through their
respective Fractional Units.
The reference frequency 19.2MHz from the crystal oscillator is divided by a ratio of 1 to 32 to create the
reference frequencies for the phase detectors.
The divide ratios can be programmed through the Reference Frequency Dividers Register.
The dividend is Desired VCO division ratio in fractional-N applications.
This number is a real number and can be interpreted as the reference frequency (F ref ) multiplying factor such
that the resulting frequency is equal to the desired VCO frequency.

4
providing 262144 steps, each of F div_ref / 2 18 (Hz).
The divider is 262144 when the ∆Σ modulator is in 18-bit mode.
With the modulator in 18-bit mode, the value to be programmed in the Main Dividend register is programmed
by the microcomputer.
This results in an error voltage when the phase differ and a constant output voltage when phase-detector input
compare in frequency and phase. If a phase error is detected, an error voltage is developed and applied to the
VCO DC offset and loop filter to reset the VCO frequency. The dividend is controlled by the frequency data
received on the SC.CLK, SC.DATA - and SC.SYN1LE- line from the microcomputer.
When a different channel is selected or when changing to the transmit or receive mode an error voltage is
generated and appears at the phase-detector output, causing the Phase Locked Loop to acquire the new
frequency.

When a different channel changing or changing to transmit or receive mode, analog switch is controlled by
VCO RX/TX for PLL lock up first.
The output of the filter is applied to the variable capacitors in transmit and receive VCO to adjust and maintain
the VCO frequency. The use of to VCO allows rapid independent selection of transmit and receive frequencies
across the frequency split.

The Rx VCO consists of low-noise silicon transistor oscillator, and followed by high-gain buffer.
The VCO is switched on and off VCO RX/TX line. When VCO RX/TX is low, the Rx VCO is turned on,
transistor Q301 is on. The Rx VCO output is typically 0dBm. The output is applied to the PLL Frequency
Synthesizer chip for VCO frequency control and as the Receiver frequency to Rx 1’st Mixer through the 1’st
Local oscillator buffer amplifier. The VCO voltage need only be set once at some frequency of the band and
split, after which it operates over the entire split with no additional tuning.
