  For details, please refer to the revised Instruction Manuals.  
  Please also update the Radio Control Program ARCP-990 and the Radio Host Program ARHP-990 which include above revisions for functional compatibility.  
         
Updated item : (Version 1.12 1.13) [November 17, 2016]
  The following symptom is revised.  
  1. In split-frequency operation, antenna relay circuit might not work correctly.  
         
Updated item : (Version 1.11 1.12) [August 3, 2016]
  The following symptom is revised.  
  1. The internal antenna tuner may not work correctly under certain conditions.  
         
Updated items : (Version 1.10 1.11) [April 20, 2016]
  The following symptoms are revised.  
  1. In a stored CW message with text entry, "%N" (contest number) may not be sent correctly under certain conditions.  
  2. In a stored CW message with text entry, the leading space character is not recognized as an interval.  
         
Updated items : (Version 1.09 1.10) [May 12, 2015]
  The following features are updated.  
  1. Adds a new algorithm within the main band NB2 (Digital noise blanker in the IF stage).  
  When pressing and holding in the [NB2] key of the main band, the NB2 function setting display appears on the main screen. This then allows toggling between "TYPE A" (conventional algorithm) and "TYPE B" (newly added algorithm) by pressing the [TYPE](F6) key. If "TYPE B" is selected, the "WIDTH" (width of the pulse noise blanking) and "DEPTH" (depth of the pulse noise blanking) parameters can be adjusted.  
    Pressing and holding in [NB2] or pressing [ESC] closes the NB2 function setting screen.
    The "TYPE A" discriminates and suppresses the pulse noise by calculating the received signal's envelope. Since the algorithm does not cut off the receiving signal, it would be effective for a weak signal buried in strong pulse noise conditions.  
    The "TYPE B" discriminates and blanks the pulse noise by calculating the transient of signal amplitude. However, it cuts off the received signal momentarily, thus allowing adjustment of the "WIDTH" and "DEPTH" to appropriate levels.  
    The "TYPE B" is not applied to the sub band due to limitations of the DSP memory capacity.  
    For both of the NB2 "TYPE A" and "TYPE B", using NB1 (Analog noise blanker in the IF stage) simultaneously, or configuring a wider roofing filter manually, it would be effective to reduce the pulse noise level under some noise conditions.
       
2. Changing of the RX IF filter passband is enabled by rotating the [HI/SHIFT]/[LO/WIDTH] knobs while transmitting.  
    If Menu No.8-01　(TX Audio Waveform Display) is set to "On" (default), the current status of the RX IF filter is not displayed in the sub screen while transmitting in SSB/AM/FM mode. If you need to view the status of the RX IF filter while transmitting in SSB/AM/FM mode, set the Menu No.8-01 to "Off".  
  Please also update the Radio Control Program ARCP-990 which includes above revisions for functional compatibility.  
         
  The following symptom is revised  
  1.   When playing and transmitting a stored CW messages with text entry, the consecutive space characters for intervals are deleted.

When the marker for the selected band becomes off-range, the scope area shifts automatically in order to display the marker near the center.("Auto Scroll" appears on the upper left side of the grid then.)
When long pressing [CTR/FIX] (F3) to apply Center mode display frequency range to Fixed mode, or pressing [MKR.CTR] in Fixed mode, the revised lower / upper limit frequencies do not overwrite the configurations in Menu No.8-05 ~ 8-32.
2.   Enables the selection of "0"(Off) for "Main Display" and "Sub Display" in "Dimmer 4" settings.
3.   Revises the behavior when AC power is switched on.
When selecting "Off" in Advanced Menu No.22 (Standby State Low Power Consumption), after AC power is switched on by pressing the main I/O power switch or switched on at the household AC outlet using the AC cable, after 40 seconds the front panel power switch LED blinks orange for a few seconds and quick start by the front panel power switch becomes available.
4.   Enables output of the 475kHz band (472~479kHz) signal from the rear panel DRV (drive output) connector as well as the 135kHz band.
5.   When frequency tracking is on, changing frequency band for the main band does not turn the frequency tracking off.
6.   Enables changing the band, mode, memory channel, or split operation settings while the CW/Voice Message screen is displayed.
  Please also update the Radio Control Program ARCP-990 which includes above revisions for functional compatibility.
