SAFETY INFORMATION The operator of any mobile radio should be aware of certain hazards common to the operation of vehicular radio transmissions. A list of possible hazards are: 1. Explosive Atmospheres Just as it is dangerous to fuel a vehicle with the motor running, be sure to turn the radio off while fueling the vehicle. Do not carry containers of fuel in the trunk. 2. Interference to Vehicular Electronics Systems Electronic fuel injection systems, electronic anti skid braking systems, etc.
within the interior of the vehicle must conform to the National Fire Protection Association standard (NEPA) 58 which requires that: a. The space containing the radio equipment shall be isolated by a seal from the space containing the LP gas container and its fittings. b. Outside filling connections shall be used for the LP gas container. c. The LP gas container shall be vented to the outside of the vehicle.
1. It is a violation of FCC rules to interrupt any distress or emergency message. As the radio operates in much the same way as a telephone "party line", always listen to make sure that the line is clear - that no one else in on the air - before sending messages. If someone is sending an emergency message - such as reporting a fire, or asking for help in an accident - KEEP OFF THE AIR! Emergency calls have priority over all other messages. 2.
The following feature encrypted options are standard with the MDX conventional mobile radio: PMPL3M Serial Control Unit (Control Head Operation) PMPL3K Scan, Dual Priority PMPL3F 16 channel operation PMPL3G 32 channel operation PMPL3H 64 channel operation PMPL3J 128 channel operation The following feature encrypted options can also be ordered: PMPL3C Type 99 Decode PMPL3D Public Address and External Speaker Switch (Requires option PMSU5A) PMPL3E Emergency (GE-STAR) and GE-STAR ANI CONTROLS
-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 AND INDICATORS CONTROLS (CONT’D) MENU Momentary switch. The MENU button is used to access options on the MDX mobile. Menu operation is coupled with the CHANNEL/SEL buttons and the CLR button. To increment from one menu selection to the next, simply press and release the MENU button. Press the CLR button to return to normal operation.
CONTROLS (CONT’D) SYS Momentary switch. The SYS (SYSTEM) button is used to select system changes. System may be incremented by pressing and releasing the SYS button. Alternately, when the display shows the System name, the CHANNEL/SEL buttons may be used to increment or decrement the system selections.
Figure 2 - Sample MDX Display TX On indicates the radio is transmitting. BSY Lights when a channel is busy (RF carrier present). SCN ON indicates scan is enabled. S ON indicates channel in scan list. P1 ON indicates selected channel is a priority 1 channel. P2 ON indicates selected channel is a priority 2 channel. PVT Reserved for future use (Aegis Communications). DISPLAY ALPHA INDICATORS The radio is capable of displaying status indicators in the alpha display.
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.
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. CONVENTIONAL MODE OPERATION 1. Select the conventional channel using +/- ramp button. 2.
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.
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.
