DOCTER DOCTER®sight C - Manual (Page 12)

Let a gunsmith do the DOCTERsight C mounting and the shooting adjustment
of the gun. Put on the cap not before the mounting has been completed.
Putting into Operation
For the power supply, one CR 2032 lithium battery (3 V) is needed. Any other kind of
power supply is excluded.
Insert the battery into the battery compartment at the bottom of the enclosure such
that the labeling of the battery with the marking of the plus pole is visible. A danger to
damage the electronics due to an incorrect insertion does not exist. For a better
contact, a magnet causes the battery to be pulled toward the gold-plated contact
plate on the circuit board. The contact area is to be kept clean (cleaning using spirit).
Replacing the battery
To replace the battery, the DOCTERsight C is to be removed from the mounting
plate. The battery compartment is located at the bottom of the device. The exhausted
battery is taken out by putting the wrench key (or the screwdriver) onto the notch
located at the right bottom side. When the battery has been replaced, the sight is put
back onto the mounting plate and is fastened with the 2 countersunk screws. Due to
the precision positioning pins, a new shooting adjustment is not required.
Switching on/off
A mechanical on/off switch is not present. To switch off the electronics, the soft cover
is put on. The putting-on effects a switching-off of the electronics.
Mounting
Due to multitude of different adapter plates, the DOCTERsight can be mounted to
nearly all gun types without any problems. Your gunsmith will choose a convenient
mounting according to your requirement and to the gun type.
Independently of the used mounting type, the upper side of the adapter plate has 4
precision positioning pins.
Put the DOCTERsight onto the mounting plate where you have to consider the
fastening threads and the positioning pins. Then, fasten the device using the
delivered countersunk screws.
The combination of screw fastening and precision positioning pins prevents the hit
point position from shifting during the use.
Shooting Adjustment
Ex factory, the optical system of the DOCTERsight III is parallax-freely adjusted to a
distance of 40 m. You have to choose a shooting adjustment distance that meets
your requirements to the DOCTERsight III.
