Further information and special functions
Battery performance
A battery will usually last for more than 15,000 closing cycles. For out-
door use, we recommend modern high-performance lithium batteries
(e.g. ENERGIZER Ultimate Lithium LR92 AAA).
Low battery
If the battery is low, the red LED flashes three times before the blue
LED lights up and accepts the code. If this happens, the batteries
should be changed. The lock will function approximately 100 more
times after the low battery signal.
Bypassing a flat or defective battery
The lock is designed so that, if the batteries are flat, a 9 V block-type
battery can be positioned against the contact poles around the red
and blue LEDs, meaning the lock can be supplied with power external-
ly, the lock can be opened and the batteries can be replaced. To do
this, proceed as follows:
Position the contact points of the 9 V block battery around the
ƒ
lock's red and blue LEDs (+ pole against the contact of the red LED
and - pole against the contact of the blue LED).
Touch the Master Smart Card.
ƒ
The motor then pulls back the lock pin and the lock can be opened.

compartment.
