    Microphone
    address
    The transceiver has 8 possible microphone addresses (in-
    cluding OFF) to help prevent interference from other HM-90
    WIRELESS MICROPHONES. Set both the microphone address
    and microphone dip switch to the same value as follows.
    NOTE:When the supplied microphone is connected, the
    transceiver rejects control signals from the HM-90 even
    when the microphone address is matched.

    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] a few times to
    select the “Adr” display as
    shown at right.
    ➃Rotate the tuning dial to
    set the microphone ad-
    dress to 0–7 or to turn the microphone control OFF.
    •When “Adr-oF” is selected, the transceiver rejects all control sig-
    nals from the HM-90.

    Beep tones on/off
    You can select silent operation by turning beep tones OFF or
    you can select to have confirmation beeps sound at the push
    of a switch by turning beep tones ON.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] one or more times until “bEP” appears.
    •Pushing [MONI] reverses the order of selection.
    ➃Rotate the tuning dial to
    select the condition.

    turned OFF.
    •“bEP-on”: Beep tones are
    turned ON.
    ➄Push [PWR] momentarily to exit initial set mode.
    Time-out timer
    To prevent accidental prolonged transmission with the one-
    touch PTT function, etc., the transceiver has a time-out timer.
    This timer cuts a transmission OFF after 3, 5, 15 or 30 min. of
    continuous transmission. This timer can be cancelled (de-
    fault).
    Approx. 10 sec. before the time-out timer passes, the trans-
    ceiver emits a beep tone as a warning.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] one or more times until “tot” appears.
    •Pushing [MONI] reverses the order of selection.

    Auto power-off
    The auto power-off function conveniently turns the transceiver
    power OFF after a preset time in which no operations are per-
    formed. In this way, when you forget to turn the power OFF,
    the transceiver automatically turns itself OFF, thereby con-
    serving battery power.
    The time can be set to 30 min., 1 hr., 2 hrs. or turned OFF.
    The selected time is retained even when the transceiver is
    turned OFF via the auto power-off function. To cancel the
    function, select “oF” in step ➃below.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] one or more times until “PoF” appears.
    •Pushing [MONI] reverses the order of selection.
    ➃Rotate the tuning dial to
    select the desired auto
    power-off time or turn the
    timer OFF (“oF”).
    •“AO” appears when an auto
    power-off time is set.
    ➄Push [PWR] momentarily to exit initial set mode.
    Cooling fan
    setting
    The transceiver has a heatsink and cooling fan to radiate
    heat. The cooling fan automatically turns ON while transmit-
    ting and remains ON for 2 min. after transmitting. The cool-
    ing fan can be activated continuously, if desired.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] one or more times until “FA n” appears.
    •Pushing [MONI] reverses the order of selection.

    (“At”) or continuous (“on”).

    Microphone [F-1]/[F-2] keys
    Switches on the transceiver’s front panel can be assigned to
    the microphone’s [F-1] and [F-2] keys.
    ➀Turn power OFF.
    ➁While pushing the desired switch on the transceiver and
    [F-1] or [F-2] on the microphone, turn power ON.
    •The switches’ function is programmed into the key ([F-1] or [F-2]).
    •Default setting
    The following functions are assigned to the [F-1]/[F-2] keys
    when first applying power or after CPU resetting:
    [F-1]: selects output power; push and hold to select duplex
    setting
    [F-2]: selects a tone function or none at all; push and hold to
    start/stop tone scan
    Display dimmer
    Adjust to suit lighting conditions and personal preference.
    ➀Push and hold [SET] one or more times until “d-1”–“d4” ap-
    pears as follows.
    •Pushing [MONI] reverses the order of selection.
    ➁Rotate the tuning dial to
    set the desired intensity.
    •Intensity can be set from “d1”
    (dark) to “d4” (bright).

    Squelch delay
    During operation, received signal strength often fluctuates.
    This can result in annoying repeated opening and closing of
    the squelch during reception of the same signal. The IC-207H
    has a built-in squelch delay function which helps prevent this.
    When both stations are operating from a fixed location, this
    function should be set to “short” e.g. packet operation.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] one or more times until “Sqt” appears.
    •Pushing [MONI] reverses the order of selection.
    ➃Rotate the tuning dial to
    set the squelch delay to
    “L” (long) or “S” (short).
    ➄Push [PWR] momentarily
    to exit initial set mode.
    USINGINITIAL SET MODE
    The display shows the squelch 
    delay function is set to short.
    Demonstration display
    A demonstration function is available at power ON. This func-
    tion gives you a quick visual introduction to the function dis-
    play indicators.
    ➀While pushing [BAND], push [PWR] to turn power ON.
    •The transceiver cycles through a visual tour of the function dis-
    play indicators.
    ➁Push any switch to exit demonstration mode and enter the
    normal operating condition temporarily.
    NOTE:The transceiver automatically returns to demon-
    stration mode after 2 min. in which no operations are per-
    formed. To deactivate the demonstration display
    permanently, turn power OFF, then while pushing [BAND],
    turn power ON again.

    Packet operation
    DData speed
    For packet operation the transceiver can be set to one of two
    data speeds: 1200 bps (default) or 9600 bps.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET], turn power ON to enter initial set
    mode.
    ➂Push [SET] one or more times until “bPS” appears.
    •Pushing [MONI] reverses the order of selection.
    ➃Rotate the tuning dial to
    select the desired data
    speed.
    ➄Push [PWR] momentarily to exit initial set mode.
    USINGINITIAL SET MODE
    The display shows the data 
    speed set to 1200 bps.
    The display shows the data 
    speed set to 9600 bps.
    NOTE:
    For 1200 bps operation—
    •Disconnect the microphone plug from the microphone
    connector during data transmission, otherwise the data
    signal and voice signal are simultaneously transmitted.
    For 9600 bps operation—
    •When the transceiver is set for 9600 bps data transmis-
    sion in INTIAL SET MODE, the microphone signal is au-
    tomatically cut. Therefore, it is not necessary to
    disconnect the microphone plug from the connector in
    this case.
    •When pushing [PTT] during data transmission, data
    transmission is interrupted and voice signals have prior-
    ity. 
    						
    							NOTE:
    •Read the instructions supplied with your TNC carefully
    before attempting packet operation with the IC-207H.
    •Pin tAF OUT is for 1200 bps operation only. This pin
    cannot be used for 9600 bps operation.
    •Over modulation may degrade signal quality. If you find
    that many transmissions are failing, re-adjust the modu-
    lation level.

    eSet transmit delay on the TNC to 30–50.
    rAdjust the TNC frequency deviation if necessary.
    •When using a deviation meter:
    Adjust the output of the TNC so that frequency deviation is in the
    range ± 3 to 4 kHz.
    •When NOT using a deviation meter:
    A receiver or transceiver is needed to monitor the transmission—
    compare the received audio output level when receiving a TNC
    modulated signal with high level voice signals using the micro-
    phone. Then adjust the TNC modulated signal to a lower level
    than the voice modulated signal.

    •When pushing [PTT] during data transmission, data
    transmission is interrupted and the voice signal takes pri-
    ority.

    D9600 bps high speed packet operation
    The IC-207H supports 2 modes of 9600 bps packet opera-
    tion: G3RUH and GMSK.
    qConnect the IC-207H and a TNC as illustrated below.
    wG3RUH mode can handle 16 kinds of modulated wave
    forms in order to maintain a communication link.
    eSet the TNC’s TX DELAY to 30–50.
