ICOM IC-M504 User Manual

■ 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 for-
mat is required for position and time indication. Ask your
dealer about suitable GPS receivers.

➥ When the connecting GPS receiver is compatible with

several sentence formatters, the order of input prece-
dence is ‘RMC,’ ‘GGA,’ ‘GNS’ and ‘GLL.’

➥ When sentence formatter ‘RMC’ is received, time indi-

cation includes a date. Thus, the ‘UTC’ or ‘Local’ indica-
tion 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.
