DSC OPERATION
■
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-M504A is not supplied
by 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.
