Radio Operation This chapter provides instructions on operation of the MICOM-H, and includes subjects such as turning the radio on, transmitting and receiving, channel mode, frequency mode, scan mode, built in test equipment, radio locking, display language and display brightness. Basic Radio Procedures To turn the radio on: Turn the ON/OFF/VOLUME knob clockwise until it clicks. The words SELF TEST are displayed for about three seconds.
Radio Operation To Transmit: Before transmitting, ensure that the RF output of the radio is connected to a tuned antenna or to a dummy load. Note To transmit, press and hold down the Push-To-Talk (PTT) button on the side of the handset and speak slowly and clearly. This method of transmission is used regardless of the type of transmission (voice, data or Morse), and regardless of whether you are in Channel, Frequency or Scan mode.
Radio Operation Bandwidth Filters Unless a particular filter is set for the current channel, the radio retains the previously used filter. When a new type of call is received or sent, the bandwidth filter changes automatically, depending on the PTT source (voice, data or CW), and the programmed bandwidth for the channel being used. Bandwidth set to: Filter changes after: LSM (data modem) first data PTT 2.1 K (voice + data) microphone or voice PTT 2.7 K (voice + data) microphone or voice PTT 3.
Radio Operation Channel Mode Channel mode is used to select a channel which is already programmed in the radio, in order to transmit/receive calls on that channel.

Installation General This section describes the installation of the radio. Inspection Carefully inspect the radio immediately upon receipt, and notify the shipper of any damage incurred in transit. Planning the Installation of your Radio Before installing the radio, familiarize yourself with the installation procedure detailed. Select the mounting location taking into account convenience of access to electrical connections and maintenance. The selected location should be clean, dry and well ventilated.
Installation Base Station Installation You can use either an AC power supply or a 12 V battery as the radio power supply . (It is possible to connect a backup battery to the battery terminals on the power supply). Power Supply model F2369 for 220 V AC, 50 Hz, field programmable for 110 VAC, 60 Hz should be used for this purpose.
Installation Mobile Installation Figure 3 illustrates the installation procedure, and shows the location of the installed components inside a vehicle. Radio ATU DC Power ca b le BAT A nten n a c ab le Figure 3: Front Model Installation The radio is installed on the dashboard of the vehicle inside the passenger compartment. The other components connect to the power source, the battery, and to the antenna, which enables the radio to transmit and receive.
Installation Mobile Mounting Kit 1. Mount the accessory mounting tray in the desired location. Use the tray as a template if holes must be drilled. 11 .8 ” (3 0 0 m m ) 8 .7 4 ” (2 2 2 m m ) Figure 4: Accessory Mounting Tray 2. Use the four supplied screws to fasten the mounting tray bracket to the bottom of the radio housing. 3. Drill an additional hole for the grounding bolt. 4.
Installation DC Power Connection To connect a 12V negative-ground vehicular battery. 1. Lead the power connector on the DC Power Cable to the DC connector on the radio, but do not attach it. Lead the three heavy wires (red, green and black) to the 12V battery, threading them through the access holes as required. The wires must be as short as possible. Cut off any excess wire. 2.
Installation Microphone Clip The microphone cable enables placing the microphone clip in any convenient location up to five feet from the radio. To install the clip, use it as a template to drill two holes to receive self-threading sheet-metal screws. Mount the clip using the supplied screws. Figure 7: Microphone Clip Final Connections ! Ensure that the radio is off before making these connections. Warning 1.
Installation External Speaker Installation An external speaker can be connected to the radio. Any speaker with an impedance greater than 8Ω can be used, and is connected through the accessory connector (pin 1,3). Operational Checks When installation is complete, carefully check all operating functions (refer to the Operation section).
