Important Notice
FCC RF Exposure Compliance Requirements
for Occupational Use Only
This radio has been tested and complies with the Federal
Communications Commission (FCC) RF exposure limits for
Occupational Use/Controlled Exposure Environment. In addition,
it complies with the following Standards and Guidelines:
• FCC 96-926, Guidelines for Evaluating the Environmental Effects of
Radio-Frequency Radiation.
• FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating
Compliance with FCC Guidelines for Human Exposure to Radio
Frequency Electromagnetic Fields.
• ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect
to Human Exposure to Radio Frequency Electromagnetic Fields,
3 kHz to 300 GHz.
• ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the
Measurement of Potentially Hazardous Electromagnetic Fields -
RF and Microwave.
• When transmitting, hold the radio in a vertical position with its
microphone 1 to 2 inches (2.5 to 5 cm) away from your mouth
and keep the antenna at least 1 inch (2.5 cm) away from your
head and body.
• The radio must be used with a maximum operating duty cycle
not exceeding 50%, in typical Push-to-Talk configurations.
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 TX is on the front panel of the radio
is illuminated. You can cause the radio to transmit by pressing the
P-T-T button.
• Always use Sporty’s authorized accessories.

Warranty
If, during the first year, your PJ2-COM transceiver fails due to defective
workmanship or parts under normal use, we will replace it or repair it at
our option.
The warranty does not apply to units subject to misuse, battery leakage,
neglect or accidents. Nor does the warranty apply to units damaged by
lightning, excess current, moisture, units repaired or altered outside the
factory, units with altered or removed serial numbers, or units used with
accessories other than those approved by the factory.
To have your unit serviced under this warranty, return it postage paid
with proof of purchase to: Sporty’s Pilot Shop, 2001 Sporty’s Dr, Clermont
County/Sporty’s Airport, Batavia, Ohio 45103-9747.
If your PJ2 COM is no longer under warranty, you may still have it
serviced at Sporty’s. See above for instructions.
Antenna Requirements
Included with the PJ2 COM is a flexible rubber antenna (Rubber Duck).
However, an external antenna may be needed if operating inside an
aircraft (must be properly installed by an aircraft radio shop), automobile
or other metal enclosure.
On top of the PJ2 COM is a BNC connector, which is standard for use
on aircraft radios. Therefore, little difficulty should be encountered in
connecting an existing aircraft radio antenna to the PJ2 COM.

Batteries
An Alkaline Battery Pack is standard equipment with the PJ2 COM.
Alkaline batteries are a good power source for a backup radio because
they have excellent storage life and no maintenance is required. The
Alkaline Battery Pack is NOT rechargeable. The batteries must be replaced.
To replace the batteries, turn the power OFF and then remove the battery
pack from the unit by holding the belt clip in the out position, and then
lift the latch mechanism found at the bottom of the battery pack.
Remove the battery cover by sliding it up. Six 1.5 volt AA Alkaline
batteries are required.
Replace the batteries by following the positive (+) and negative (-)
terminal markings inside the case. When the batteries are replaced,
replace the battery cover and attach the battery pack to the radio.
To attach the battery pack, make sure the power is OFF. Slide the
battery pack onto the back of the and push in on the bottom until it
locks in place.
If the radio will not be used for a long period of time (six months or
more), please remove the batteries from the battery pack. This will prevent
the batteries from corroding the battery pack.

Precautions:
• Changes or modifications not expressly approved by the
manufacturer for compliance could void the user’s authority to
operate the equipment.
• Never attempt to service this unit yourself. It should be referred
to qualified service personnel. Please read the Warranty section in
this manual.
• If liquid spills or some solid object falls into the unit, remove the
battery pack or external power adapter and have the unit checked by
a qualified person before further operation.
• Never dispose of batteries or battery packs in a fire. They
may explode.
• Never leave weak or dead batteries in the Alkaline Battery Pack. They
may leak and cause permanent damage.
• Never store a battery pack where it may be accidentally shorted.
• Use only the approved external power adapters and battery packs.
• Never touch an external antenna when the danger of lightning
is present.
• Do not leave the transceiver near heat sources, such as radiators or
air ducts, or place the transceiver in an environment where the
radio will be subjected to moisture, excessive dust, shock or
mechanical vibration.
• Abrasive cleaners or chemical solvents may mar or damage the
case. Clean the transceiver with a soft cloth dampened with a mild
detergent solution.
• If operating the transceiver at temperatures outside the range of
-20°F to 122°F (-30°C to 50°C), the LCD (screen) may not display
the selected frequency. If the PJ2 COM is used in temperatures
lower than the recommended range, the characters being displayed
may change very slowly. These irregularities will disappear, with
no harm to the PJ2 COM, when operation is resumed within the
recommended temperature range.
