GENERAL DESCRIPTION
The VERTO zero NFC locking system is an electronic knob lock based on NFC technology, designed for indoor use. This
user manual provides the informa on required for correct opera on of the locking system. Keep the user manual in an
easily accessible place. Improper use may damage the locking system and will void any warranty claims.
Be sure to observe all warnings and read the user manual completely before star ng installa on, commissioning,
and programming.
The use of this locking system in combina on with addi onal mechanical or electronic solu ons from other manufactu-
rers must be checked for compa bility. No liability is accepted for damage resul ng from incompa bility.
Text and graphics have been prepared with care. However, no liability is accepted for any errors that may s ll occur. Chan-
ges to the scope of delivery and technical specifi ca ons may be made without prior no ce.
CAUTION: The locking system is confi gured using the LEHMANN Confi g App and operated exclusively with the
LEHMANN Transponder App. The Transponder App is available for iPhones and Android smartphones
in the respec ve app store. The Confi g App is currently available for Android smartphones (the iOS
version will follow shortly). Ensure that NFC transmission is enabled on your smartphone. The quality
of NFC transmission may vary depending on the device.
SAFETY PRECAUTIONS
→ Pack the lock for transport in such a way that it cannot be damaged.
→ Dispose of packaging material in accordance with applicable na onal regula ons (see Disposal).
→ Do not heat, disassemble, or short-circuit the lock.
→ Never throw the lock into open fi re.
→ Keep the lock, supplied components, and packaging materials away from children.
→ Damaged components may cause injury.

FACTORY SETTINGS
At this stage, the locking system can be locked and unlocked using the “Installa on Test” func on in the LEHMANN
Confi g App. A er a profi le has been taught in using the LEHMANN Confi g App, the locking system is set to “Assigned
Use” mode. Opera on of the lock via the “Installa on Test” func on is no longer possible.
CARE AND MAINTENANCE
→ Protect the components of the locking system from moisture.
→ Clean the locking system only with a clean, so , and slightly damp cloth.
→ Do not use harsh cleaning agents containing abrasive substances or solvents. Glass cleaners, thinners, alcohol,
gasoline, or liquids containing ammonia are not suitable for cleaning.
→ Improper handling of all electronic and mechanical components, devia ng from this user manual, may lead to
malfunc ons.
FUNCTIONAL DESCRIPTION
With the VERTO zero NFC locking system, you can conveniently lock and unlock your furniture. The knob on the
lock is operated manually by the user. Contactless NFC technology is used as the “key.” Two operating modes
are available:
Lock opera ng mode
Descrip on
Assigned Use
There is a fi xed assignment between the LEHMANN Transponder App (comparable to a user
card) and the locking system. The Transponder App is programmed or deleted at the lock using
the LEHMANN Confi g App.
The locking system allows selec ve access authoriza on, ensuring that only authorized persons
are granted access. The Transponder App can be programmed simultaneously on mul ple locks
in “Assigned Use” mode.
Shared Use
A user can use any lock of their choice with the LEHMANN Transponder App. Programming the
Transponder App using the LEHMANN Confi g App is not possible.
When a lock is locked using the Transponder App, the Transponder App and the lock are linked.
The Transponder App cannot be used on any other lock in “Shared Use” mode, and the lock will
not accept any addi onal users. This link is only released when the user unlocks the lock again
using their Transponder App. The Transponder App can then be used again for another lock in
“Shared Use” mode.
In the addi onal mode “Unlimited Shared Use,” a user can lock mul ple locks simultaneously
with the Transponder App (note: even all locks), instead of only one lock per Transponder App.
Unlimited Shared Use
With the LEHMANN Transponder App, the user can operate any lock of their choice. When a
lock is locked using the Transponder App, the app and the lock become linked. This link remains
ac ve un l the user unlocks the lock again using their transponder.
In "Unlimited Shared Use" mode, mul ple locks can be locked simultaneously with a single
Transponder App.
WARNING: A single Transponder App can lock all locks confi gured in this mode. Therefore,
the intended use should be carefully evaluated and adapted to the specifi c applica on
requirements.

OVERVIEW OF THE SMARTPHONE APPS
App
Descrip on
LEHMANN
Confi g App
The LEHMANN Confi g App includes, among other features, the “Installa on Test” func on, which
allows the basic func ons (locking / unlocking) of the lock to be tested. As long as a lock is in the factory
default state, the “Installa on Test” func on can be performed universally from any smartphone with
the Confi g App. For full commissioning, a profi le must be created in the Confi g App and transferred to
the lock. The profi le is required to carry out programming procedures on the lock. This also includes
teaching in users or smartphones with the LEHMANN Transponder App in “Assigned Use” mode.
The Confi g App with a profi le also enables an electronic emergency opening of the lock. A maximum of
one profi le can be assigned per lock. One profi le can be used for mul ple locks.
A er crea ng and transferring a profi le to the lock, the lock can only be confi gured in the Confi g App
using the corresponding password and project ID. Store the password and the project ID of the profi le
carefully in a secure place.
LEHMANN
Transponder App
The LEHMANN Transponder App func ons like a transponder or user card at the lock and is used to
lock and unlock the lock. Mul ple users can be programmed on a lock in “Assigned Use” mode.
In “Shared Use” mode, the Transponder App can only lock one lock at a me. It is possible to use
the Transponder App on mul ple locks in “Assigned Use” mode and at the same me on one lock in
“Shared Use” mode.
IMPORTANT: Smartphones have varying NFC transmission strengths. Transmission quality and speed depend
on the smartphone and should be checked in advance if necessary.
Store the password of the profi le carefully in a secure place. Programming procedures and
rese ng the lock are not possible without the password.

NOTES FOR THE FOLLOWING PROGRAMMING STEPS
The LEHMANN Confi g App is used to confi gure not only NFC locks, but also
keypad and fi ngerprint locks. Therefore, select “NFC” in the bo om right of the
app. Please note that the app is divided into two sec ons: “Profi le” and “Direct.”
A er ac va ng programming mode on the lock using the Confi g App, this mode
remains ac ve for 30 seconds. End the programming mode using the Confi g App.
Alterna vely, the programming mode ends automa cally a er 30 seconds.
Users (Transponder Apps) taught in or deleted within these 30 seconds will
be saved.
Both the Confi g App and the Transponder App must be
open / ac ve during use.
During data transfer from the smartphone to the lock, hold
the smartphone’s NFC antenna directly against the lock’s
reading area. Data transfer does not work with distance between the smartphone
and the lock! Wait for the confi rma on on the display. Repeat the process
if necessary. This is especially important in "Shared Use" mode.
Carry out all programming procedures and func onal checks
with the cabinet door open.
BOLT END POSITION MONITORING
The lock is equipped with a bolt end posi on monitoring system. If the knob is not in one of the two end posi ons,
