Only authorised personnel are permitted to replace the battery. Use only batteries
that are supplied by SimonsVoss.
1. Firmly hold the knob and remove the locknut on the back of the knob from the
knob with the special tool for half cylinders.
2. Use an authorised transponder to couple the cylinder and unscrew the knob
by turning it counter-clockwise. While doing this, you must firmly hold the
catch with your hand if the half cylinder is not installed. If the half cylinder is
installed, the catch is held by the stop within the lock.
3. Replace the main and emergency batteries. Make sure that the polarity is
correct.
4. Use an authorised transponder to couple the half cylinder and tightly screw
the knob in until the stop
. Make sure that the knob is screwed on up to the
stop (important for the function). While doing this, you must firmly hold the
catch with your hand if the half cylinder is not installed. If the half cylinder is
installed, the catch is held by the stop within the lock.

Dispose of used batteries immediately, keep out of reach of children, do not open and
do not throw into a fire!
& Reversing the polarity can result in damage to the locking cylinder. Incorrect
handling of the batteries used in this device can result in the risk of fire or
burns. Do not charge, open, heat to more than 100° C (212° F) or burn.
& Never operate the cylinder without a main battery because otherwise the
entire power consumption of the cylinder runs over the backup battery.
& For PLUS versions, you must reset the time of day after the battery change
because the clock does not work without current (Software Operating
Instructions: Programming Æ Setting the clock on the locking).
