Instructions for use (from the original card)

INSTRUCTIONS FOR OPERATING
THE COLUMBUS CLOCK-CONTROLLED RADIO
MODEL 563 

GENERAL: The Columbus Clock-Controlled Radio will perform any of the following functions automatically:
 (1) Operates the alarm buzzer at any time for which it is set.
 (2) Switches the radio on at any preset time.
 (3) Switches the radio off after any period of time up to one hour.
In addition, the two units may be used separately - as an electric clock and a manually-operated radio receiver.
 
STARTING: The self-starting movement of the clock will operate (indicated by sweep second hand) as soon as the switch controlling the power point is turned on. Set the correct time with the "HANDS-SET" knob on the back of the cabinet.
 
RADIO MANUAL: To operate the receiver in the normal manner Turn the "RADIO" knob to "MANUAL". This switches the receiver on and illuminates the dial scale. Turn the volume control knob to approximately the middle of its range. After about 1/2 minute warming up period select the desired station with the tuning knob and re-adjust the volume. 
Returning the "RADIO" knob to "OFF" switches off the receiver.

SLUMBER CONTROL: It is possible to have the radio playing for any period up to sixty minutes and then to switch itself off automatically. To do this, set the "SLUMBER" knob, which is situated at 9 o'clock on the clock face, to the desired period of time and also the "RADIO" knob to "OFF". For example: If the user retires at 10 p.m. and sets the "SLUMBER" control to 45 minutes and the "RADIO" knob to "OFF", the set will remain playing and switch itself off automatically at 10.45 p.m.
 
RADIO-ALARM: If you desire to be awakened by music, or wish to have the receiver switch on automatically at any time (e.g., a favourite radio programme) turn the "RADIO" knob to "MANUAL" and tune into the desired station. Pull out the "ALARM" knob and turn anti-clockwise until the desired time on the rotating dial is indicated by the short extension of the hour hand. Turn the "RADIO" knob to "ALARM". The receiver will then switch on approximately at the alarm time which is indicated on the alarm-setting dial. The buzzer will operate approximately ten minutes later if the alarm knob is left extended. Pressing the knob silences the buzzer.
A combination of the above two features provides both slumber music and radio alarm. Set the "SLUMBER" control to the desired period and the "ALARM" knob to the time for the radio to commence playing and the alarm to sound. Switch the "RADIO" Knob to "ALARM"
CAUTION: When adjusting the "ALARM" control, always rotate it in the direction indicated by the arrow on the "ALARM" knob. Turning it in the wrong direction may upset the accuracy of the alarm setting movement or cause other damage to the clock mechanism.
⋆ IMPORTANT: Having once completed the alarm cycle it is essential that the clock mechanism be reset by switching the "RADIO" knob to either "OFF" or "MANUAL" before again resetting the slumber and alarm facilities.
 
INDEPENDENT ALARM OR TIMER: To use the clock buzzer as an alarm or timer, switch the "RADIO" knob to "OFF", or to "MANUAL" to retain the use of the receiver. Set the alarm with the "ALARM" controls and leave the spindle extended. This arrangment allows timing of any operation (cooking, etc.) by the buzzer without automatic switching off of the radio receiver. NOTE — The buzzer operates approximately ten minutes later than the alarm setting (e.g., if the alarm setting is 7 o'clock the buzzer operates at approximately 7.10).

General Construction Notes for Radio Corporation of New Zealand Ltd: The first digit of the serial number typically indicates the year of manufacture of RCNZ chassis' (although not the decade - that requires a little knowledge of the valves, construction, etc). Sets from around 1934 onwards were often (but not always) constructed in a distinctive pressed 'baking pan' style chassis, seemingly unique to RCNZ.
