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
Clermont County/Sporty’s Airport
2001 Sportys Drive
Batavia, Ohio 45103-9719
If your PJ2+ COM is no longer under warranty, you may still have it
serviced at Sporty’s. See above for return address 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 (if installed) in the out position, and
then lift the latch mechanism found at
the bottom of the battery pack. Remove
the battery cover by pulling the thumb
latch in the direction of the arrow. Six 1.5
volt AA Alkaline batteries are required.
Energizer batteries are the recommended
battery for the PJ2+ COM. Results may
vary when using off brand batteries.
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 help
prevent the batteries from corroding the battery pack.

External Power
The PJ2+ COM includes a wall adapter and USB-A to USB-C power cable.
The wall adapter can be used in 100-240 volt applications. The USB-A port
on the wall adapter provides the needed 2.4 amps to properly power the
PJ2+ COM. If less than 2.4 amps is provided, the PJ2+ COM will receive
transmissions, but it won’t have enough power to transmit. If attempting
to transmit on less than 2.4 amps, the PJ2+ COM screen will flash
intermittently and beep. To remedy this issue, change the power source to
provide the needed 2.4 amps, or use the alkaline battery pack.
The PJ2+ COM does not have power delivery capability. Power should
only be provided from a USB-A port.
Another option for external power is to use a backup tablet battery pack
(sold separately). Be sure to use a battery pack that provides at least
2.4 amps of power.
Note: When powering the PJ2+ COM through the Type-C power port on
the side of the radio, the radio will transmit at 5 Watts (PEP).

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.

Operating Instructions
To perform the following functions you must be in the basic operating
mode of the PJ2+ COM. To ensure that you are in the basic operating
mode, press the Clear key until the last frequency that was entered
manually is displayed.
Manual Frequency Selection
The PJ2+ COM will receive and transmit on the 760 COM frequencies
(118.000 MHz to 136.975 MHz). The frequency currently selected
is always displayed at the top of the PJ2+ COM’s screen and the last
frequency is always underneath the current frequency.
From the example above, the PJ2+ COM is receiving 122.975 MHz with
the last frequency being 121.000 MHz. To manually enter a desired
frequency such as 118.700 MHz, enter 1 1 8 7 0 0 using the numeric
keypad. As each digit is entered, the flashing cursor moves to the next
digit. Six digits may be required to select a frequency.
The PJ2+ COM will return to the previous frequency if there is a pause
of five seconds between key entries while entering a new frequency. The
Clear key may be pressed at any time prior to entering the sixth digit to
clear the digits entered and return to the previous frequency.
Any frequency outside of the range listed above will not be accepted. The
PJ2+ COM will beep when such a digit is entered. For example, starting
any frequency selection with a number other than 1 or attempting to
place a 5, 6, 7, 8 or 9 in the second digit will result in a beep.
The PJ2+ COM can flip flop between the current frequency and the last
requency by pressing the button above the PTT on the side of the radio.
Manual_final.indd 14 7/13/22 1:51 PM
15
Frequency Search
To manually search through the frequency range, the Up key or Down key
may be pressed at any time to select the next higher or lower frequency.
The Up and Down keys may be pressed repeatedly to continue changing
the selected frequency.
To automatically search the entire frequency range for a broadcasting
signal, the Up key or Down key may be pressed and held for one second.
The Screen will display SEARCH as seen below.
The frequencies will either scroll up or down depending upon whether
the Up or Down key was used to initiate the Search.
When a broadcasting signal is found, the word SEARCH will flash and the
PJ2+ COM will stop temporarily on that frequency. If the broadcasting
signal is cut off for more than two seconds, the Search will resume until
another signal is found. When 136.975 MHz is reached during a upward
Search, the Search automatically continues at 118.000 MHz. Likewise,
when 118.000 MHz is reached during a downward Search, the Search
automatically continues at 136.975 MHz.
The Search may be canceled at any time by pressing the Clear key. The
direction of the Search may also be reversed at any time by pressing
and holding the Up and Down key (whichever is appropriate) for one
second. It is very important that the Squelch be properly adjusted prior
to initiating a Search. The background static received with the squelch off
may be strong enough to disrupt a Search. If a Search gets “stuck” on a
frequency with too much background noise, increase the Squelch or press
and hold the Up or Down key for one second to skip that frequency and
resume Searching.
