    Changes from Version 1.30

    [Added DPD function]

    • Supported the Digital Pre-Distortion (DPD) function.

    Pre-adjustment is required to use the DPD function. Refer to "Information IC-7610 Version 1.41" for details.

    [Added linkage function with IC-PW2]

    • Supported for the Linked manual tun​ing with IC-PW2.
    • Supported for the IC-PW2 Dual Connection Mode.
    • Supported for the IC-PW2 Transmission Interlock control.

    [Any other changes]

    • Improved the Manual All Reset operation.

    When the All Reset cannot be performed from the RESET screen, holding down the [MAIN/SUB] and [CHANGE] keys and turning ON with the [POWER] key will manually perform an All Reset. The Manual All Reset operation is improved by connecting the external power supply in​stead of the [POWER] key.

    • Fixed a bug that caused the Noise Squelch to sometimes not work when the operation mode was set to the FM mode while the Dualwatch or the Split function was ON.

    For details, please refer to "Information IC-7610 Version 1.41."
