INSTALLING THE BATTERIES

1. Pull out the insulation sheet in the direction of the arrow to switch on power from the already placed batteries.

2. "86-1-1" will appear in the LCD window.


Chinon Infoback 3 NOTE: 1. Even though some broken characters might appear instead of "86 - 1 - 1", it is in the normal operation as well.

2. When the LCD panel blinks continuously, the batteries should be replaced immediately as they are too weak to operate the INFO BACK-3 properly.

 

Chinon Infoback 3 Replacement of batteries
The INFO BACK-3 automatically checks the power voltage when the batteries are installed and whenever imprinting data. When the voltage is too low to operate the unit, all LCD panel indications will blink, Replace the batteries with a fresh set at once (use two of the same kind of batteries such as 3V CR-1/3N, 3V DL-1/3N or 3V 2L76 lithium battery).

Installing the batteries
1. Insert a sharp pointed object into the area marked (see drawing) and lift to open the cover.

2. Take out the old batteries and install two of the same kind of 1/3N type lithium batteries. Do not mix battery brands or mix old with new ones since it might cause battery leakage or an explosion.

3. Close the battery cover. When new batteries are installed, all the data memories will be erased and have to be set again.

 

NOTE:

1. At low temperatures, the battery performance will decline and the LCD panel warning will blink.
    Brought back to the normal temperatures, proper performance will resume.

2. Use of the unit at temperatures between -10°C and +50°C (14°F and 122°F) is recommended for
    normal operation of the liquid crystal.
 
 

Chinon Infoback 3 ATTACHING TO THE CAMERA 1. Open the back cover of the camera and push down on the retaining pin with your fingernail to remove the back cover.

2. To mount the INFO BACK-3 insert its lower shaft into the lower hinge. Then depress the retaining pin,
    align it with the upper hinge and let go of the pin to lock it in.


 
 

Chinon Infoback 3 FILM SPEED SETTING 1. When using DX-coded film, the film speed is automatically set by the camera body and
    the appropriate imprinting brightness is adjusted automatically as well.

2. When using non-DX film faster than ISO 400, it is suggested that only the "no data" mode be utilized.


    NOTE: 1. When using specialized film such as infrared, it is also suggested to use the "no data" mode.

2. When using film with other than ISO 100-1600, the imprinted data may be faint or blurry.
    It is also suggested to use the "no data" mode.
