The Flexo.Code impresses with its versatile application and
installation options. The innovative design lock offers the
possibility of individual time control with adjustable closure
duration and up to 999,999 code variants.
Like all locks in the Flexo range, the code variant allows both
recessed installation (flush fit) and retrofitting (retro fit). Thanks
to the possible one-, two- or three-point locking with latch
function, it adapts conveniently to any installation situation.
Important: Please observe all warnings and read through
the entire operating instructions before you begin with
the configuration.

Flexo.Code | 01-2023 Rev. 01 | English | 4
Mode: Fixed Assigned Authorization (Private Mode)
In this mode, a code is pre-set with which the lock can be
operated. This mode is suitable for user groups where user
rights do not have to change permanently, e.g. in an office
cabinet. To close, the user enters a stored code. The lock is
opened by entering this or another stored code. Up to 50 codes
can be stored. A code that has not been stored is rejected by the
lock.
Mode: Multi User Authorization (Multi User Mode)
This mode is suitable for constantly changing users who only use
the compartment temporarily or once, e.g. in a sports facility.
Codes are valid for a single locking process and are deleted by
the lock when the compartment is reopened so that a new code
can be used. The locking bolt remains open until a new code
locks the lock again. Before locking, the door must be closed
(slightly pressed). The user enters a code of choice (4 or 6 digits)
to close. The green LED starts flashing. The lock is opened by
entering the same code.
Code Confirmation (Multi User Mode)
To lock the lock, the code must be entered twice. The lock only
locks after the second entry. The second entry is made after the
green LED flashes briefly. A simple code entry is sufficient to
open the lock. This function can be turned on or off.
Master Code
The Master Code authorizes the programming of the lock. In
addition, the Master Code can unlock the lock independently
of the set mode (emergency opening) and terminate the block
mode. In Multi User Mode, the code used for locking is deleted
after the Master Code is entered.
Note: We recommend programming a private Master Code
before putting the lock into operation.
LED Locking Indication
The lock indicates the locked state by flashing the red LED every
second. This function can be turned on or off.
Automatic Locking (Private Mode)
The lock locks automatically after three seconds after unlocking.
The door does not have to be closed for this. The latch function
allows the door to be closed by pressing slightly even with the
lock locked. This function can be turned on or off.
Functional Description
Functional Description RTC
The Flexo.Code also has an integrated software real-time
clock (RTC) that can be used to program time-related functions.
The functions and the defined times must be specified when
ordering.
Automatic Locking / Unlocking at a certain time
The lock locks and unlocks automatically at a defined time. The
times can be set separately for each day of the week.
Programming is carried out by BURG.
Time Window Usage
The lock can only be operated within the individually defined
time-of-use period. The lock cannot be operated outside this
period. The times can be set separately for each day of the
week. Programming is carried out by BURG.
Closure Duration
The closure duration defines the maximum period for which a
lock may be locked from the time of locking. After expiry of the
locking period, the lock opens automatically. Programming is
carried out by BURG.
Battery Warning
If the battery capacity falls below a certain limit, the red LED
lights up for three seconds after the code has been entered. If
the critical level is reached, the lock can no longer be locked or
can only be opened with the Master Code.
Note: We recommend changing the battery already after the
first warning.
Block Mode
After three consecutive failed opening attempts, the lock locks
for 45 seconds. During this period, no action is possible on the
lock. The locking time is indicated by the red LED flashing every
second. The locking mode can be cancelled by entering the
Master Code.

the nut with a socket wrench (SW22).
Place the latch and fasten it with the Torx screw (Torx 30)

Disposal and Battery Note
Image rights: cover, wood texture, Torsakarin / 123rf
EU Directive 2012/19/EU regulates the proper take-back,
treatment and recycling of used electronic equipment.
Every consumer is required by law to dispose of batteries,
accumulators or electrical and electronic equipment („waste
equipment“) powered by batteries or accumulators separately
from household waste, as they contain harmful substances
and valuable resources. Disposal can be done at a collection or
take-back point approved for this purpose, e.g. a local recycling
center. Waste equipment, batteries or rechargeable batteries are
accepted there free of charge and recycled in an environmentally
friendly and resource-saving manner.
Waste equipment, used batteries or rechargeable batteries can
also be returned to us. The return must be sufficiently stamped to
the address below.
The following symbol on the waste electrical equipment,
batteries or accumulators indicates that they must not be
disposed of with household waste:
Caution when using batteries!
The battery may explode or release flammable gases if it is
mishandled, destroyed, or the wrong type of battery is used. Do
not recharge the battery, disassemble it, expose it to extremely
high temperatures or throw it into a fire.
On batteries containing harmful substances, you will find
indications in the form of abbreviations for the ingredients
cadmium (Cd), mercury (Hg) and lead (Pb) in each case.
