    DAdjusting the transmit signal output from
    the TNC
    When setting data transmission speed to 9600 bps, the DATA
    signal coming from the TNC is applied exclusively to the in-
    ternal limiter circuitry to automatically maintain band width.
    NEVER apply data levels from the TNC of over 0.6 Vp-p, oth-
    erwise the transceiver will not be able to maintain the band
    width and may possibly interfere with other stations.
    1. When using a level meter or synchroscope, adjust the TX
    audio output level (
    DATA INlevel) from the TNC as follows.
    0.4 Vp-p (0.2 Vrms): recommended level
    0.2 Vp-p–0.5 Vp-p (0.1 Vrms–0.25 Vrms): acceptable level
    2. When NOT using a measuring device.
    qConnect the IC-207H to a TNC.
    wEnter a test mode (“CAL”, etc.) on the TNC, then transmit
    some test data.
    eWhen the transceiver fails to transmit the test data or
    transmits sporadically (TX indicator doesn’t appear or
    flashes):
    Decrease the TNC output level until the transmit indicator
    lights continuously.
    When transmission is not successful even though the TX
    indicator lights continuously:
    Increase the TNC output level.

    Fuse replacement
    If the fuse blows or the transceiver stops functioning, find the
    source of the problem if possible, and replace the damaged
    fuse with a new, rated one (FGB 20 A) as shown in the dia-
    gram below.
    Partial resetting
    If you want to initialize the operating conditions without clear-
    ing the memory contents, etc., a partial reset function is avail-
    able for the transceiver.
    While pushing [V/MHz], turn power ON to partially reset the
    transceiver.
    ➧Initialized settings:VFO frequency, SET mode settings.
    ➧Retained settings:Memory channels, call channels, offset
    freq. in memory/call, DTMF memory, ini-
    tial SET mode settings.
    Resetting the CPU
    The function display may occasionally display erroneous in-
    formation, (e.g. when first applying power). This may be
    caused externally by static electricity, or by other factors.
    If this problem occurs, turn power OFF. After waiting a few
    seconds, turn power ON again. If the problem persists, per-
    form the following procedure.
    Partial resetting is alternatively available. See previous sec-
    tion for details.
    ➀Push [PWR] to turn power OFF.
    ➁While pushing [SET] and [S.MW], turn power ON.
