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.
