OPERATION MANUAL
IMPORTANT SAFETY INFORMATION
Before installing and using your radio, please read this
operation manual.
GENERAL PRECAUTIONS
Always use only Midland authorized accessories.
Unauthorized accessories have the risk of fire hazard, explosion,
personal injury or damage to the radio.
CAUTION
Changes or modifications to your radio may void its compliance with
government laws/rules and make it illegal to use.
Avoid using the radio at temperatures below -30ºC or above 60ºC.
Avoid storing the radio at temperatures below -40ºC or above 85ºC.
WARNINGS
Your Midland Syn-Tech III P25 Mobile Radio generates electromagnetic
RF energy when it is transmitting. To ensure that you and those around
you are not exposed to excessive amounts of that energy (beyond
recommended allowable limits for occupational use):
DO NOT operate your radio without a proper antenna. Otherwise, you
can seriously damage your radio.
DO NOT touch the antenna when you are transmitting.
NEVER connect the transceiver to any AC power source. This may cause
an electric shock or fire hazard and will damage your radio.
NEVER connect the transceiver to a DC power source either greater than
16 volts or with reverse polarity. Doing so will damage the transceiver.
DO NOT attempt to service any internal parts yourself. Please ask your
dealer for necessary service. This radio should be opened by authorized
personnel only.
Please read the installation and operating instructions carefully.

OPERATION MANUAL
FCC EXPOSURE STATEMENTS
Restricted to occupational use to satisfy FCC RF energy exposure limits.
The FCC has adopted a safety standard for human exposure to RF energy. Proper operation
of this radio under normal conditions results in user exposure to RF energy below the
Occupational Safety and Health Act and Federal Communication Commission limits.
Mandatory Safety Instructions to Installers and Users:
This radio is NOT approved for use by the general population in an uncontrolled environment.
This radio is restricted to occupational use and work related operations only. Radio operators
must have the knowledge to control their exposure conditions and the exposure conditions of
bystanders and/or passengers to satisfy the lower exposure limit allowed for General
Population.
To comply with FCC RF exposure limits, DO NOT operate the transmitter of this mobile radio
when a person outside the vehicle is within the minimum safe distance from the antenna:
50W VHF – 22 inches (56 centimeters)
110W VHF – 31 inches (79 centimeters)
40W UHF – 18 inches (45 centimeters)
The antenna supplied by the manufacturer or radio dealer must be mounted at a location such
that during radio transmission, no person or persons can come closer than the above indicated
minimum safe distance to the antenna. To comply with current FCC RF exposure limits, the
antenna must be installed at or exceeding the minimum safe distance stated above, and in
accordance with the requirements of the antenna manufacturer or supplier.
Vehicle Installation Instructions:
The antenna used for this transmitter must be mounted on the center of the roof ONLY and
must be installed in vehicle having the following characteristics in order to prevent bystanders
and passengers from being exposed to levels exceeding the limits for General
Population/Uncontrolled Exposure environment:
1. All passengers must be sitting under a solid metal roof.
2. For rear deck trunk and roof top installations, the antenna must be located at least the
minimum safe distance away from rear-seat passengers and bystanders in order to
comply with the FCC RF exposure requirements.
DO NOT operate the radio without the proper antenna installed. Do not substitute any antenna
for the one supplied or recommended by the manufacturer or radio dealer. Antennas used for
this transmitter must not exceed an antenna gain of 3 dBi. By not following the antenna
recommendations you may be exposing person(s) to excess radio frequency radiation. You
may contact your radio dealer or the manufacturer for further instructions.
DO NOT transmit more than 50% of total radio use time (50% duty cycle). Transmitting for
more than 50% of the time can cause FCC RF exposure compliance requirements to be
exceeded. This radio is transmitting whenever the Transmit/Receive LED is red. Pressing the
PTT switch on the side of the microphone normally causes the radio to transmit.
680-090-2041
Version 6.0
The preceding information is provided to make you aware of RF exposure
and how to ensure that this radio is operated within FCC RF exposure
limits.
You, as the qualified end-user of this radio device must control the exposure conditions of
bystanders to ensure the minimum separation distance, stated above for satisfying FCC RF
exposure compliance, is maintained between the antenna and nearby persons. Transmit only
when all person(s) are at least the minimum distance from the properly installed, externally
mounted antenna.

OPERATION MANUAL
3.2 Button and Key Functions
Below is a brief description of the default operation of each button or key. For more
details of each function refer to the operation section of this manual. Many of the
functions may be reassigned or disabled by radio programming or unavailable because
of the current analog/digital mode selection. Many of the buttons have a short press, or
press and release function, and a long press, or press and hold function. The short
press function is performed if the button is pressed for less than one second, and the

function may allow all NACs and talk groups to be received on digital and mixed
channels. While monitor is on, a long press of the Monitor/Call Wait key turns monitor
off.
A short press of this key turns the call wait option on. The call wait option is available
only on digital channels. When the call wait option is on, group calls will be muted. If an
individual call (addressed to the radio) or all call is received, the call will be heard and
the call wait option will be canceled. While call wait is on, a short press of the
Monitor/Call Wait key turns call wait off.
3.2.8 Keypad Lock (short press)/Emergency Reset (long press) key

OPERATION MANUAL
4 OPERATION
4.1 Basic Operation
Despite the radio’s advanced feature set, the basic receive and transmit operations can
still be quite simple. The radio is capable of distinguishing between analog and digital
signals, and the channel may be configured to receive both signal types with no user
intervention. The radio channel may also be configured to allow users to transmit
analog signals, digital signals, or choose the appropriate transmit mode. The radio may
also automatically switch the transmit mode after receiving a different mode signal. The
radio will switch back to the selected mode after a time period.
4.1.1 Turning the Radio On and Off
Press and release the On/Off Volume Knob to turn
the mobile radio on. Press and hold the On/Off
Volume Knob at least two seconds to turn the mobile
