■ Position and time indication
When a GPS receiver (NMEA0183 ver. 2.0 or 3.01) is con-
nected, 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-M504 is not supplied
by Icom. A GPS receiver with NMEA0183 ver. 2.0 or 3.01
format is required for position and time indication. Ask your
dealer about suitable GPS receivers.
➥ When the connecting GPS receiver is compatible with
several sentence formats, the order of input prece-
denceis‘RMC,’‘GGA,’‘GNS,’‘GLL’and‘VTG.’
➥Whensentenceformat‘RMC’isreceived,timeindica-
tionincludesadate.Thus,the‘UTC’or‘Local’indication
is not displayed.
➥ “ ??” may blink instead of position and time indications
when the GPS data is invalid, or has not been manually
updated after 4 hours.
