This manual provides specifications for the EE-420R Electronic Shelf Label (hereafter referred to as 
“ESL”). 
 

 
The EE-420R is an Electronic Shelf Label with a 2.4GHz radio for data communication. The product 
has a 3-color E-ink based e-paper display with black, white and red pixels. This product uses Direct 
Sequence Spread Spectrum RF technology that allows for an ultra-low power consumption combined 
with a reduced sensitivity to background noise. That means less interference by other radios that 
operate in the 2.4GHz band. The radio protocol that is used is based on the IEEE 802.15.4 standard 
that specifies the physical layer and media access control for low-rate wireless personal area 
networks. The protocol is entirely implemented, except for some small changes that have all to do with 
the connection protocol to a base station. When the base station is not available the EE-420R 
switches to a non-802.15.4 standard to lower the power. That is especially meaningful when the EE-
420R is not being used for a prolonged period of time (e.g. during shipping)  
 
The EE-420R is intended to be operated in combination with a base station such as the EBS-40 which 
can control a large number of EE-420R and other types of ESL of the same family such as EE-202 
and EE-750.
