Position and Time display
When a GPS receiver (NMEA0183 ver. 2.0 or 3.01) is
connected, the transceiver displays the current position and
time. When no GPS receiver is connected, the transceiver
displays the manually entered position and time.
A GPS receiver appropriate for the IC-M604A is not supplied
from Icom. A GPS receiver in NMEA0183 ver. 2.0 or 3.01
format is required for position and time indication. Ask your
dealer about suitable GPS receivers.
➥
With a receiver that is compatible with several
sentence formats, the order of input precedence is
‘RMC,’ ‘GGA,’ ‘GNS’, ‘GLL’ and ‘VTG.’
➥
When sentence format ‘RMC’ is received, the time
display includes a date. Thus, the “UTC” or “Local” icon
is not displayed.
➥
“

been interrupted for 10 minutes, or has not been
manually updated for 4 hours.
