■ 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-M505 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.
