OPERATING PROCEDURES Two-way FM radio systems must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). Operators of two-way radio equipment must be thoroughly familiar with the rules that apply to the intended type of radio operation. Following these rules will help to eliminate confusion, assure the most efficient use of existing radio channels, and result in a smoothly functioning radio network. When using this two-way radio remember these rules: 6 1.
INTRODUCTION This manual describes how to use the MDX Conventional Mobile Radio. The MDX is a synthesized, microprocessor-based, high performance simplex mobile FM radio providing reliable two-way communications. Direct mobile to mobile communication, when out of repeater range, is also provided. In the Conventional mode, the user selects a channel and directly communicates on that channel. In this mode, a system refers to a set of channels and a channel is a transmit/receive radio frequency pair.
-Character Alphanumeric Dot Matrix LED allows you to identify channel selections by descriptive names. Names, menu options, and status information are displayed here. PWR MENU button allows access to functions and options, including scan add/delete for modifying the radio’s scan list and alarm on/off for the external alarm option that uses your horn or head lights to signal an incoming call. Emergency ID/ Alarm (optional) sends an emergency (GESTAR) alert and identifying code to the dispatcher.
CONTROLS, INDICATORS, AND DISPLAYS The MDX Conventional mobile radio contains ten buttons, an eight character DOT MATRIX display and seven indicators (see Figure 1). In addition, there are times when part of the eight character display is used to display the radio status. Backlighting on buttons illuminate the Legends. CONTROLS POWER Momentary push-push switch. Press once to turn the radio ON. Press again to turn the radio OFF. VOLUME The momentary switches (auto ramping) VOLUME + and VOLUME -.
CONTROLS, INDICATORS, AND DISPLAYS 8-Character Alphanumeric Dot Matrix LED allows you to identify channel selections by descriptive names. Menu options, and status information are displayed here. PWR MENU button allows access to functions and options, including scan add/delete for modifying the radio’s scan list and alarm on/off for the external alarm option that uses your horn or head lights to signal an incoming call.
CONTROLS (CONT’D) MENU - Cont. ALARM ON/OFF: Press the MENU button until "ALM ON" or "ALM OFF" appears in the display. Press the CHANNEL/SEL + or - buttons until the desired state is selected. (Note: This enables or disables the external alarm, e.g. horn or lights.) SQUELCH Press and hold "Scan" button, use "volume" up to loosen squelch and down to tighten squelch. SYS Momentary switch. The SYS (SYSTEM) button is used to select system changes.
NUMERIC KEYS 1-9, 0, *, # On system radio, the twelve button keypad permits transmission of DTMF digits. DISPLAY INDICATORS The radio’s display is shown in Figure 3. The character line is used to display system or area and group or channel names and also operational messages to the user. The line contains eight Dot Matrix LED characters. The 7 status indicators are used to show the various operating conditions of the radio. Figure 3 - Sample MDX Display TX On indicates the radio is transmitting.
DISPLAY ALPHA INDICATORS - Cont. T99 Off Menu display indicating T99 option is disabled. Pub Addr Public address option enabled. ALERT TONES The MDX Conventional mobile radio generates a set of unique alert tones to indicate operating status. The following section identifies and describes the alert tones used in the MDX radio. SELF CHECK TEST ALERT One beep is sounded after the radio is turned on to indicate that the radio has passed the self diagnostic test. Optional in PC programmer.
2. Set the volume using the VOLUME RAMP button. A short beep sounds each time the VOLUME button is pressed. The beeps will not sound if a call is being received. SELECT To select a different channel when you have selected a conventional system: 1. Press the CHANNEL/SEL + or - ramp button until the desired channel name appears in the alphanumeric display. A tone sounds each time the channel name changes unless the BSY indicator is on.
3. Decide what you want to say. If you intend a lengthy message (or several messages), the vehicle engine should be running to maintain the battery charge. 4. Observe the BSY indicator and then press CLR the switch to assure that the channel is not in use. 5. Remove microphone from the hanger, press the PTT switch and identify yourself. The TX indicator will be shown each time the PTT switch is pressed. 6. Release the PTT switch and wait for an answer to your call. Then complete your message. 7.
3. Press the CHANNEL/SEL (+) button until the desired priority level is displayed by the scan priority indicators on the right side of the display; the choices are S, P2; P1 or all off (all off removes the channel from the SCAN list). 4. Press the CLR button when completed to return to normal operation.
Scan operation will be determined by the following conditions: • PRIORITY 1, PRIORITY 2 and NON-PRIORITY PROGRAMMED The Priority 1, Priority 2 and up to 14 remaining channels will be scanned. Once a carrier is detected (and if programmed, the correct Channel Guard is decoded), the display will indicate that channel. Sampling of the Priority 1 and Priority 2 channels continues while receiving a message.
SCN indicator When the SCAN button is pushed, the radio will light the SCN indicator and begin scanning. The SCN indicator will flash when the microphone is placed off-hook to show the radio is no longer scanning (only if the radio is PC programmed not to scan off-hook). Transmitting While In Scan: Transmitter operation in scan is determined by the PC programming of the radio’s personality. A flow chart is provided in this section to summarize the scan operation described below.
Monitor (CLR) Switch Operation In Scan The CLR switch does not operate while scanning inactive channels. When a channel becomes active, the CLR switch operates only during the scan hang time after the channel activity disappears. Channel Changes In Scan Pushing the channel switches (UP or DOWN) while scan is turned on will change the SELECTED channel assignment. If a signal is being received and the channel switches are pushed, the radio will revert to the new SELECTED channel assignment.
AEGIS OPERATION NOTES Each channel can be programmed for ANALOG Voice, Aegis Digital Voice, or Aegis VGE Encrypted Digital Voice mode of operation by programming the "KEY" variable. When programmed "DIS", a channel will only operate in the ANALOG mode. ANALOG voice calls can be easily monitored by unauthorized persons. When programmed "DIG", a channel will only transmit Aegis Digital Voice. Aegis Digital Voice and ANALOG Voice calls can be received.
CLEAR MODES In clear mode the radio transmits and receives only analog voice signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be easily monitored by unauthorized persons. Channels programmed for clear operation cannot transmit or receive Aegis digital messages. AEGIS DIGITAL MODE Aegis digital mode allows the radio to transmit and receive digitized voice signals.
When operating on a channel programmed for digital mode, all transmissions will be digital transmissions and the radio will receive clear and digital signals. The PVT light turns on when the private mode is enabled. If the selected channel is programmed for autoselect capability, the mode may be toggled between digital and clear with the flex keys (A1, A2). Radios programmed for forced operation do not allow a change of the transmit mode; therefore, the flex keys would have no effect.
M 2. Use the button to select DISP KEY. 3. Then use the CHANNEL/SEL button to toggle between displaying the system key or the channel key. ENCRYPTION KEY DISPLAYED MESSAGE DISPLAYED System "SYS KEY" "KEY = 1" Channel "CHN KEY" "KEY = 2" KEY ZERO C All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while still pressing this button, press and hold the OPT button. Press both buttons for 2 seconds.
If the last state of the radio was digital mode, the digital mode will be enabled on power up. Also the digital mode will be enabled if forced operation has been programmed in the radio. If a channel is not programmed for digital mode operation, PVT DIS will be displayed if an attempt is made to enable digital transmit mode. It is not possible to operate on this channel in digital mode.
OPTIONS Type 99 Option If the Type 99 Option is present, individual selective calling is possible. Press the programmed Flex key or use the menu and CHANNEL/SEL keys to enable the decoder option (Scan must be off). The LED display will show the option status: "T99 ON" or "T99 OFF". Press the button a second time to toggle the option status. The display will revert to normal channel display after 5 seconds.
OR 1. Make sure the radio is turned ON. 2. Press the A1 or A2 button (pre-programmed). When PUB ADDR appears in the display press the PTT switch to transmit the microphone audio to the external speaker. 3. After the PA operation is completed, press the A1 or A2 button to return to normal operation. INTERNAL/EXTERNAL SPEAKER When the Internal/External Speaker Option PMSU5A has been installed along with an external speaker, the operator can select either speaker one of two ways. 1.
