recognised, the low battery warning appears once. The
blue LEDs flash three times and engagement does not
occur.
CHANGING THE BATTERIES
Tapkey Smart Lock
Follow the steps below to change the battery:
Caution: In the event of electrostatic discharge
(sparks or breakdown), electronic components
may be destroyed. For this reason, avoid elec-
trostatic charges prior to the (dis)assembly of
the knob sleeve or touch a conductive, groun-
ded object (e.g. water pipe, heating) before-
hand to remove electrostatic charge from your
body. Never touch the electronics components
with your fingers.
Please note: Only use the 3.0 Volt lithium
battery from Tapkey which is already pre-
assembled with the connection cable.
Unlock the bayonet fitting using the knob tool and
carefully pull off the knob sleeve.
Fig. 18: Removing the knob sleeve
Pull the battery connector from the battery socket
and remove the old battery pack. (Make sure
you pull on the connector and the three cables at
the same time, not only on one or the cables.)
Insert a new battery.
Please note: The battery connector has a torsi-
on-resistant guide lug.
Insert the battery connector into the battery socket.
Caution: Do not damage the battery cable
when fitting the knob.
Place the knob tool on the bayonet fitting.
Slide the knob sleeve accurately over the electro-
nics holder. The knob sleeve can only be slid on in
one position. The two drive cams on the electronics
holder have different widths.
Lock the bayonet fitting using the knob tool. Pre-
sent an authorised transponder in order to check
whether the cylinder is working perfectly after the
batteries have been changed.
