4.5 Reception of a teleprinter message
Reception of a teleprinter message is possible at any time. With button EH
depressed, all telegraph signals are printed and punched. In an unattended
station this button and the DECI button should always be depressed so that
messages that cannot be deciphered (e.g. SPECAT messages) are available also
in perforated tape form.
