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.
Syn-Tech III P25 Portable Radio OPERATION MANUAL 680-090-2040 Version 5.0eng http://www.midlandradio.com iiiFCC 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.

Syn-Tech III P25 Portable Radio OPERATION MANUAL 680-090-2040 Version 5.0eng http://www.midlandradio.com 134 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. 4.1.1 Turning the Radio On and Off Rotate the On/Off Volume Knob clockwise past the detent to turn the radio on. Rotate the knob further clockwise to increase the speaker volume. Rotate the knob counter-clockwise to decrease the speaker volume. Rotate the knob counter-clockwise past the detent to turn the radio off. While the radio is performing power-on self-tests, it will display the greeting message and the current zone selection. If the channel switch is in the sixteenth position, the radio will power-on to the last selected channel. In any other position the radio will power-on to the switch-selected channel. If a power-on password has been set, the radio will prompt for password entry when it is turned on. Use the numeric keypad to enter the correct password then press the left soft key (OK). If the password is entered incorrectly five times, the radio will lock and must be reprogrammed to reset the password. Enter 5 digit password Press OK to continue Figure 4.3 – Power-on password entry Figure 4.1 – On/Increase Volume Figure 4.2 –Off/Decrease Volume

SMS messages are free text messages sent from one radio to another. With SMS messages, the message (up to 160 characters maximum) is entered using the alpha-numeric keypad and transmitted to the other radio. Predefined messages are common messages among all radios. A predefined message is selected from the predefined message list (of 20 messages of maximum 20 characters) and the message pointer is transmitted to the other radio. Status messages are common status settings among all radios. A current status is selected by the radio user (of 30 status settings of maximum 20 characters), and may be sent to another radio. Your current status may also be queried by another user. Both status and predefined messages rely on the receiving radio’s database to determine the message displayed. The message characters are not sent, instead only a pointer of which message should be displayed is sent. For proper status and predefined messaging operation, both the receiving and transmitting radios should be using the same message database.
