    Each coast station, Alaska-public fixed station and Alaska-private 
fixed station must provide operating controls in accordance with the 
following:
    (a) Each station using telegraphy or telephony must be capable of 
changeover from transmission to reception and vice versa within two 
seconds excluding a change in operating radio channel.
    (b) During it hours of service, each station must be capable of:
    (1) Commencing operation within one minute after the need to do so 
occurs;
    (2) Discontinuing all emission within five seconds after emission is 
no longer desired. The emission of an unattended station in an automated 
multistation system at which restoration to standby is automatic on 
conclusion of a call must be discontinued within three seconds of the 
disconnect signal or, if a disconnect signal is not received, within 
twenty seconds after reception of the final carrier transmission from a 
ship station.
    (c) Each station using a multichannel installation for telegraphy 
must be capable of changing from one telegraphy channel to any other 
telegraphy channel within the same sub-band below 525 kHz within five 
seconds. This requirement need not be met by equipment intended for use 
only in emergencies and not used for normal communication.
    (d) Every coast station using a multi-channel installation for 
radiotelephony must be capable of changing from one telephony channel to 
another telephony channel within:
    (1) Five seconds within the frequency band 1605-3500 kHz; or
    (2) Three seconds within the band 156-162 MHz. This requirement also 
applies to marine utility stations.
