      Joanna NelsonSep 9, 2025
      If your Icom Transceiver displays “??” instead of the position and time, it could be because 23.5 hours have passed since you manually entered the position, or the GPS position is invalid. To resolve this, enter the current position and time.

      Mr. Jerry Miller Jr.Sep 12, 2025
      If you cannot transmit with high power on your Icom Transceiver, it could be due to a couple of reasons. Some channels may be set for low power or receive only, according to regulations. Try changing channels. Alternatively, the output power may be set to low. Push the [HI/LO] button to select high power.

      If you cannot set the Individual or Group ID on your Icom Transceiver, it is likely that the entered ID code is incorrect. For an Individual ID, the first digit must be between '1' and '9.' For a Group ID, the first digit must be '0.' To resolve this, enter a correct ID code.
