OPERATION MANUAL
IMPORTANT SAFETY INFORMATION
Before 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 Portable 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. Transmitting
without an antenna may damage your radio.
DO NOT touch the antenna, or allow the antenna to touch any
bystanders, when you are transmitting.
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.
This radio is NOT approved for use by the general population in an uncontrolled environment.
This radio is restricted to occupational use, work related operations only, where the radio
operator must have the knowledge to control the user’s exposure conditions for satisfying the
higher exposure limit allowed for occupational use.
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm)
away from your mouth. The radio is transmitting when the red Transmit/Receive LED on the
top of the radio is illuminated. You can cause the radio to transmit by pressing PTT on the
side of the radio.
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. 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
information.
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 radio normally causes the radio to transmit.
DO NOT allow the antenna to touch any part of your body while transmitting.
DO NOT transmit while the radio is attached to your belt.
KEEP the radio and antenna at least as far from bystanders as from yourself.
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.

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
long press function is performed if the button is pressed for more than one second.
3.2.1 Channel Switch
The channel switch provides direct access to channels 1-16 in the current zone. In the
sixteenth position, the up/down and direct channel entry modes may be available. If the
channel switch is in the sixteenth position, the radio will power on to last selected
channel. In any other position, the radio will power on to the switch-selected channel.
3.2.2 Emergency Call Button
The emergency button initiates emergency mode. The emergency function is only
available in digital mode. The emergency key must be pressed for a programmed
activation time. Once emergency mode is activated, the radio will switch to the
emergency channel and initiate five SBC emergency transmissions. The emergency bit
will be set on all user initiated digital transmissions until the emergency is cleared by a
long press of the keypad lock key or the radio is turned off.
3.2.3 Alpha-Numeric keypad
When the channel switch is in the sixteenth position, the alpha-numeric keypad may
provide direct channel select from standby mode. The alpha-numeric keypad also
generates DTMF tones while PTT is pressed on analog channels and enters alphanumeric characters within other functions.
Direct channel entry mode is only available if more than sixteen channels
are programmed in the zone.
