L0428R - ROLLING CODE PROGRAMMER AND ANALYZER
Features
L0428R programmer is equiped with a 433.92 MHz radio-receiver (Receiver 1) in order to get the codified signals from
Leb electronics transmitters. The unit can be equipped with an extra radio-receiver (Receiver 2) with different frequency
(e.g. 868,35 MHz).
Use of the device
The electronic unit is intended for the following uses :
 Verify operating status of SMARTY, TPW4/TPK4. TSAW4N transmitters
 Codify SMARTY, TPW4/TPK4 transmitters.
Limitations to use
 L0428R programmer operates correctly only with SMARTY, TPW4/TPK4. TSAW4N transmitters
 Secret Key System works only with Leb electronics receiver RSK4/RPSK4
 It is possible to verify codes of transmitters (installation code and Tx code) only with the original L0428R programmer that was
used to program transmitter. No other L0428R than the original one can do it.
General specifications
Power supply: 9V alkaline battery
Operating range: 1 m of distance approx. from transmitter
Operating temperature range : from +10 to +50 °C
Dimensions: 94 x 180 x 39 mm
Weight: 220 gr
Installation codes: 4096 max.
Transmitter codes: 4096 max. for installation

L0428R - Operation
Preliminary operations
Battery replacing
Turn off the programmer. Unscrew the two screws on the front side of the housing and remove the cover. Replace the battery
respecting the polarity of the connector. Place the cover of the housing as in origin.
Programming cable connection
To program Leb electronics transmitters, insert the plug of the programming cable into the socket C.
Turning on the programmer
To turn on the programmer, press the following key:
The display will show "0428R Analyzer SECRET KEY" and programmer is ready to program Leb electronics remotes in SECRET
KEY mode.
To switch to programming in FIXED CODE mode, press F2. Display will show “0428R Analyzer FIXED CODE MODE”.
To turn off the programmer, press again
Radio-receiver selection
The unit operates with 433.92 MHz Receiver 1. To select the optional Receiver 2, press the key 2and verify that “ RECEIVER 2 “ is
displayed. To restore operation with Receiver 1 press the key 1 and verify that “ RECEIVER 1 “ is displayed.

Operations
Attention: In order to avoid undesired signals, the operating range has been reduced to 1 m of distance.
The programmer operations consist of 4 menus.
Menu 1 To codify transmitters in order to store them manually into receiver of
a selected installation.
Menu 2
To codify a transmitter in order to store it automatically in a selected
installation. This feature is very useful when in need to store a new
code in the receiver without going onto the installation.
Menu 3
To codify a transmitter in order to replace (and cancel) a selected
stored transmitter code. This feature is very useful when in need to
remove and replace a code in the receiver without going onto the in-
stallation.
Menu 4 To set automatic power off and automatic backlight of display.
To select the desired menu, do the following:
 Turn on the programmer
 Press the F1 key
 Scroll the menus through the keys.
