DTFCATO 2.1 The KS Raidial (Fig. 1 and 2) is a magnetic-tye reertory dialer used in conjunction with a customer telehone set. t records, stores, and transmits dial ulses. 2.2 Connecting a Raidial to the telehone set will not affect the normal oeration of the telehone. For ease of oeration, the Raidial should be located near the telehone set. 2.3 Cord connections are required between the telehone set and the Raidial and between the Raidial and the low-voltage ower suly. The ower suly (List 2) is shown in Fig. 3 and Raidial rovides writing sace for the entry of 29 names and telehone numbers on a revolving tae. A scan knob on the right side of the machine is rovided for manual rotation of tae. The List 1 Raidial has a motor-driven tae for raid scanning. 2.5 ames and numbers are written on the tae with a lead encil so changes can be made, if required, by erasure. nstruct subscriber to use kneadable eraser to revent eraser residue from darkening tae. 2.6 The dial on the Raidial unit is used only to record numbers on the tae and is inoerative (locked), when the unit is not in recording condition. 2.7 The list numbers for the comonents are: (a) KS-16844, List 1 Raidial includes: elist 3-Power Suly Cord (4 conductors, 8 feet long) elist 4-Telehone Cord (6 conductors, 8 feet long)' elist 6-Tae Assembly (Manual) (b) KS-16844, List 1 Raidial includes: elist 3-Power Suly Cord (4 conductors, 8 feet long)' elist 4-Telehone Cord (6 conductors, 8 feet long)' elist 12-Tae Assembly (Power Driver) (c) Housings are not included with the List or List 1 Raidial.

5 SS 4, SCTO Power suly may be mounted with three o. 6 or 8 wood screws. Two retaining screws hold cover in osition (Fig. 3). Power suly cord is fed through cutout in cover and secured under cord clam. 3.8 Raidialis shied with List 3 ower suly cord terminated. Cut free end of cord to desired length, outer jacket, twist stranded conductor ends, and terminate on ower suly. (5) Back off on screw aroximately one to one and a half turns so that clicking sound disaears. On ower driven scan model, also check that scan switch is free in both directions. SCA KOB 3.9 Power cord shall lug into a 115-volt ac recetacle not under control of a wall switch. The low voltage ower suly consists of two voltages: 19.5 and 26.5 volts ac. Raidial is rotected by a 24C, 2-amere fuse located on in ower suly (Fig. 4). 3.1 Raidial is shied with List 4 telehone cord terminated. (1) Cut free end of cord to desired length. (2) Stri outer jacket and twist stranded conductor ends. (3) Terminate conductors in telehone set as outlined in Table A, B, C, D, or. (4) Secure cord, inside telehone set, under cord clam or by taing it to telehone set mounting cord. (5) Make certain conductors are roerly dressed so as not to interfere with normal oeration of telehone set After assembling Raidial, it is necessary to adjust start bar for oeration. This is accomlished in the following manner: (1) Connect to ower outlet. (2) Position Raidial uside down. (Be sure to rotect cover from scratches.) (3) Start bar adjustment screw can be reached through base of Raidial by aligning hole in the instruction card with hole in base (Fig. 6). (4) Using a 3-1/2 inch screwdriver, turn screw clockwise and revolve scan knob until a clicking sound is heard.

6 SCTO Oeration of record bar automatically erases a ortion of the telehone number reviously recorded on magnetic tae. When demonstrating Raidial, turn writing tae to a blank sace before oerating record bar. 4.3 When the record bar is oerated, a small red button is exosed. Pressing this button injects a time delay of three seconds between digits being recorded. Only one time delay er comlete recording is ossible. An examle of a required time delay would be the ause, after dialing digit 9 from a dial PBX station, for a central office trunk connection. Since central office dial tone may not be heard immediately, a time delay is rovided to revent Raidial from ulsing before central office dial tone is available. 4.4 The List 1 Raidial (List 12 tae cartridge) is equied with a scan switch and limit switches to revent running the tae off the drums. The writing tae is imrinted with a series of dots which corresond with the guide letters on the bottom of the lastic window. Final adjustments to line u desired number between guide lines on window is made with manual scan knob. 4.5 To record a telehone number, roceed as follows: (1) Check directory listing of number. (2) Locate an unused sace on writing tae for new entry by rotating scan knob. (3) Move release latch to right and slide record bar down. (4) Use iead encil to enter name and telehone number on writing tae. {5) Record new telehone number by using dial on Raidial. Refer to 4.3 for use of time delay button. Raidial is caable of recording 13 digits. (6) Restore record bar by releasing latch. 4.6 To lace a call, roceed as follows: (1) Oerate scan switch and rotate scan knob until desired telehone number aears between horizontal black lines on lastic window. (2) Lift telehone handset. (3) Wait for dial tone. (4) Deress start bar. (5) f there is a delay in dial tone and Raidial has started ulsing before central office dial tone is heard (for examle, when dialing a central office from a dial PBX station), customer should hang u immediately. Raidial will continue ulsing through a comlete cycle with an on-hook condition of the associated telehone set. (6) When lacing call from a key telehone set, caution customer not to answer an incoming call on another line while Raidial is ulsing. Raidial circuitry is common to all lines in the set and hence the ulsing will be carried over to the answered call. 4.7 To remove a recorded telehone number from Raidial: (1) Position the number between horizontal black lines on lastic window. (2) Oerate latch and record bar (see 4.2). (3) Remove entry from writing tae with an artist's rubber kneadable eraser such as Faber-Castell. (4) Restore record bar. 5. COCTOS 5.1 Raidialulsing contacts (BL and G telehone cord conductors) are laced in series with the ring side of the line for 2-tye telehone sets, and in series with dial contacts in all other rotary and TOUCH-TO dial sets. 5.2 Two sets of off-normal contacts (Fig. 5 and 7) are rovided. Their function is the same as the off-normal contacts in a conventional dial, to reduce receiver clicks during oeration of Raidial. e White off-normal leads are laced across receiver in telehone set.
