Antenna selection, installation and positioning requires knowledge of RF radiation and exposure conditions and should be performed by qualified personnel only. Please consult your dealer or communications coordinator for more information. © 2013, Midland Radio Corporation http://www.midlandradio.com Base Tech IV P25 Base/Repeater Station Basic Operation Before turning on your radio for the first time, you should ensure power connections have been made correctly and all antenna connections are proper and secure. Turning the Radio On and Off Press and release the power button. The power LED should light indicating the radio power is on. The radio will perform some software loading and checks then display the channel. To turn the radio off, press and release the power button again. If “Password?” is displayed after turning on the radio, you must enter the programmed password (4 keypress sequence) to use the radio. Consult your dealer or communications coordinator if you have further questions. Channel Selection Press and release the rotary encoder knob until the channel is displayed. While the channel is being displayed, rotate the rotary encoder knob to select the desired operating channel. Please consult your dealer or communications coordinator regarding channels programmed in your radio. Receiving Transmissions from Other Radios Each channel of your radio may be programmed for analog receive operation, digital receive operation, or mixed (both) receive operation. The following paragraphs describe these modes of operation. Ask your dealer or communications coordinator if you have questions on how your radio has been programmed to operate. Analog Receive Operation If the channel is not programmed with CTCSS/CDCSS, a signal that matches the programmed receive frequency will be heard if it is of sufficient strength to exceed the squelch threshold. An on frequency signal exceeding the squelch threshold level will be indicated by a lit Busy indicator and speaker unmute indicator. © 2013, Midland Radio Corporation http://www.midlandradio.com Base Tech IV P25 Base/Repeater Station CTCSS or CDCSS signaling adds an additional condition to carrier squelch operation. In addition to the signal having to exceed the squelch threshold level, the received signal must also have the correct CTCSS tone or CDCSS code before the audio will be passed to the speaker. CTCSS or CDCSS signaling allows multiple users on the same frequency to hear only signals which have their correct CTCSS tone or CDCSS code. An on frequency signal with the correct CTCSS or CDCSS signaling will be indicated by a lit Busy indicator and speaker unmute indicator. A Busy indicator with the speaker mute indicator means that the channel is busy, but the correct CTCSS or CDCSS signaling is not present. CTCSS/CDCSS allows multiple users to share the same frequency. However CTCSS/CDCSS is only useful to avoid disturbing other users with messages not related to them. If more than one radio is transmitting at the same time, this will cause interference. Do not transmit if the Busy indicator is lit. Wait until the channel is clear before transmitting. Digital Receive Operation When a P25 digital transmission is received, it will be heard if the required conditions are met. P25 digital signals have several mechanisms to allow users to hear only conversations intended for them. A received P25 digital signal will be indicated by lit Busy and Digital indicators. The primary condition the P25 digital signal must match is the Network Access Code, or NAC. The NAC provides much the same functionality as CTCSS/CDCSS do for an analog signal. The received signal will only be heard if the NAC from the received signal is matched to the channel parameters. There is a special NAC, hexadecimal F7E, which indicates to the receiver to allow signals received with any NAC to be heard. This provides much the same functionality as an analog signal without CTCSS/CDCSS. The P25 digital signal may be further addressed to everyone, to a specific talk group, or to an individual unit ID. If the receiver is 10 © 2013, Midland Radio Corporation http://www.midlandradio.com Base Tech IV P25 Base/Repeater Station configured for normal digital squelch mode, all signals with matching NAC will be heard. If the receiver is configured for selective squelch mode, only signals addressed to the proper talk group or individual ID will be heard. Mixed Receive Operation If the radio channel is programmed for mixed receive operation, the radio will receive both analog and P25 digital signals. The receiver will automatically switch to the appropriate mode depending on which type of signal is detected. Analog and P25 digital receive operation is as described above. Transmitting to Other Radios Before transmitting, the FCC requires you monitor the channel to make sure it is clear. Transmitting while someone else is transmitting will create interference and disrupt both conversations. The radio is capable of transmitting both analog and P25 digital signals. The radio channel is configured for a default transmit mode. The current transmit mode is indicated on the LCD display, and by the lit Digital indicator (when digital TX Mode is selected). A programmable function button may be set up to allow the user to choose the desired transmit mode. Follow these steps to transmit to other radios. 1. Check that the radio is in the desired transmit mode. 2. Monitor the channel by pressing the programmed function button. Channel activity is also indicated by the lit Busy indicator. 3. If the channel is clear, press and hold the push to talk (PTT) switch on the side of the microphone. 4. The Transmit indicator will light while the radio is transmitting. 5. Hold the microphone approximately 2 inches from your mouth and speak across the face of the microphone in a clear, normal voice. © 2013, Midland Radio Corporation http://www.midlandradio.com 11 Base Tech IV P25 Base/Repeater Station 6. Keep the PTT switch pressed until you have finished speaking. 7. Release the PTT switch to return to receive mode. Press PTT before you start talking and release PTT after you have finished speaking. The radio might be programmed with a timeout timer which will automatically end your transmission after a preset time. In this case release PTT and wait for a few seconds. The radio transmitter will be enabled again after a few seconds. Ask your dealer or communications coordinator for further details. The radio might be programmed for busy channel lock out, which automatically disables the transmitter if your channel is busy. In this case wait until the channel is clear. 12 © 2013, Midland Radio Corporation http://www.midlandradio.com Base Tech IV P25 Base/Repeater Station Programmable Functions For increased flexibility and customization, the four front panel buttons may be programmed with the following functions: Monitor Press and release this button to toggle the monitor mode.
