Instruction Manual - Nikon SB-1 Flash Unit

4) ASSEMBLING

(A) Attaching the Bracket to the Main Unit
  1. Turn the end of the band fastening screw clockwise, using a coin or the like, so that the band is sufficiently released to accept the Main unit grip.

  1. Remove the bottom cap of the Main unit.
  2. Insert the grip of the Main unit through the band, with the top (engraved "TILT") of the bracket holder turned upward. The ridge on the side of the Main unit grip is to be fitted into the groove on the bracket holder. (Photo 3)
  1. Refasten the band in position on the Main unit. It will be convenient to bring the top (engraved " TILT ") of the bracket holder flush with that of the ridge on the side of the Main unit.
  2. Replace the bottom cap of the main unit.
  3. Attach the bracket to the bracket holder and fasten it with the bracket fastening screw.
  4. It is recommended to leave the band attached to the Main unit in this position, even when the bracket is not used

For convenience in carrying the Main unit without the camera, the bracket can also be hung with the end of the bracket fastening screw pushed into the clip hole (adjacent to the marking '' Nikon "), the rubber lining being faced inward. (Fig. 2). For removal, only pull it out,

(B) Depositing NiCd Battery
  1. Unscrew the bottom cap of the Main unit.
  2. Push in the battery with its plus (+) end turned upward. It cannot be deposited in reverse position.
  3. Replace the bottom cap of the Main unit. Note : The NiCd battery, even though delivered fully charged, will drain to some extent by self-discharging for a long time, even if not used.A complete recharge will take about 4 hours after a lapse of one month and 5 hours after that of 3-4 months. For recharging, refer to p. 13.
(C) Attaching the bracket to the camera
  1. Screw the attaching screw on the bracket into the tripod socket of the camera. (Photo 4)
  2. Connect the synch. socket on the Main unit with that on the camera by means of the Synch. cord SC 1 (15 cm).

5) PREPARATION AND SYNCHRONIZATION
(A) Preparation
  1. Switch on the power switch. A high pitched hum will be heard, which cuts out after a few seconds when the neon pilot lamp lights. Now, the Main unit has been fully charged and is ready to be fired.
  2. After the pilot lamp has been lighted, oscillation sounds of short intervals will come on again, showing that the automatic voltage stabilizing circuit in the Main unit is operating, which serves to keep the light output constant at all times. Release the shutter, and the correct synchronized firing will take place. Note: The synch. selector on the Nikon F should be set to FX and the shutter speed to 1~60 sec. or slower. On the Nikkormat the Synch. cord is to be connected to the synch. socket X and the shutter speed to 1 125 sec. or slower.
  3. * Open flash button: This button which is generally used for firing while the shutter is set to B and fully opened. It can also be used for firing test.

6) AC UNIT & CHARGER SA-1: The AC unit (Photo 7) is used for firing the Main unit connected to the house current or for re charging the NiCd battery. Therefore, it can be used for recharging the NiCd battery, while the Main unit is being used with AC.

(A) Changing AC Input Voltage: Turn the circular part of the input voltage change-over switch on the side of the AC unit, using a coin or the like, until the red dot comes opposite to tile AC voltage to be used.

(B) Using the AC Unit as Power Source
  1. Connect the power source cord with a 4 pin-plug tightly at an end to the AC socket on the Main unit, with the cord being parallel to the Main unit as shown in Fig. 3, For this connection, however, the power switch on the Main unit must be turned off.
  2. Connect the AC cord to the main AC supply.
  3. About 5 seconds after, the neon pilot lamp an the Main unit will light, giving indication of the readiness for firing. If the AC unit is not used for a long period, it may take a longer time. In this case, repeat firing several times to regain the normal condition.


(B) Calculating Dial
  1. When using GN Auto Nikkor lenses
    1. Set the ASA scale on the calculating dial to the film type index (Colour or Black White).
    2. The figure appearing in the sector window on the dial shows the guide number.
    3. Bring the guide number setting pin on the GN Auto NIKKOR to the above read out guide number.
    4. Thereupon the f-number will automatically be changed according to the focused distance given on the lens.

  1. When using other NIKKOR lenses: 
    1. Set the ASA scale on the lower disc to the film type index (Colour or Black & White) an the top disc. Then, the user will read out at a glance the correct f-number with the subject distance at which he is working or, vice versa, the subject distance corresponding to the f-number.
Example 1. Type of film. ASA 25 (Colour) Distance of subject: 12 feet Turn the ASA scale until ASA 25 comes opposite to the red index COLOUR on the fixed scale. The correct aperture of lens will be about f/4 for the distance 12 feet. (Photo 5)

Example 2. Type of film ASA 125 (Black & White) Distance of subject: 9 feet Set the ASA 125 on the revolving scale to the index B & W The correct f number will be about f 16 for the distance 9 feet. (Photo 6).

Caution: When the AC unit is to be used for a long time, the NC battery may be recharged too far. It is necessary to take out the battery from the Main unit to avoid the possibility of deterioration of the battery due to over charge.

(C) Recharging the NC Battery
  1. For this purpose, only connect the AC unit to the Main unit the same way as when it is used with AC power. The power switch on the Main unit, however, should be turned off.
  2. When the NC battery has been completely discharged (fully used), recharge will take 14-16 hours. Recharging is to be carried on as long as a discharged output is fully recovered. Therefore, if an output of about 50% has been discharged, a complete recharge will take 7-8 hours. A discharged output can be approximately estimated by the number of firings. If fully charged, the unit can be used 80 flashes. So, if the unit has been fired about 40 flashes, the discharged output must be about 50%.

7) BOUNCE FLASH

Release the bracket fastening screw on the bracket. (It is not necessary to detach the bracket from the bracket holder.) Turning the white dot on the bracket in the direction of the arrow, change the tilting angle of the bracket by choosing an appropriate hole (provided at every 30'), into which the positioning pin is to be fitted. (Fig. 4). Fasten the bracket in position. It will be convenient to locate the bracket halfway or slightly higher on the Main unit grip.

8) EXTENSION FLASH: The Nikon Speedlight unit permits additional firing of up to 2 units besides the Main unit at the same time.

  1. (1) Attach the Main unit to the camera in the usual manner.

sb1image8.jpg
  1. When one additional unit is used, connect the extension socket on the Main unit to the extension or synch. socket on the additional Main unit using the extension cord SE-1.
  2. When two additional units are to be used, connect the synch. or extension socket on the flrst additional unit to the extension or synch. socket on the second additional unit respectively. (Photo 8) Note: No extension flash is possible when using the Ringlight unit SR-1 or Macro ringlight unit SM-1.
