Three types of radio signal reception are possible: automatic reception, on demand reception and recovery automatic reception. There are three modes where reception is possible time (TME), calendar (CAL) and receive set (RX-S). The watch cannot receive signals in any other mode.
To obtain the setting instructions specific to your watch, you will need to provide the Movement Calibre on your watch case back. The movement calibre number typically comprises four digits, starting with a letter (e.g., E870).
