Disposal of Waste Electrical and Electronic Equipment (WEEE) in the 
European Union 

 

This symbol on the product and package indicates that this product 

must not be disposed with unsorted municipal waste. Instead, it is 
your  responsibility  to  dispose  of  WEEE  by  handing  it  over  to  a 

designated collection point for the disposal. The separate collection 
and recycling of waste equipment will help conserve natural 

resources and ensure that it is disposed in a manner that protects 
human health and the environment. For more information about 

where you can drop off your waste equipment for disposal, please 
contact your local municipal office, waste disposal service or where 

you purchased the product. 

Components  

The Cadex Duro charger package includes these items: 
1 Duro 

Charger 

1 or 5 Adapters with screws. The screws are taped inside 
the adapter screw hole (see installation instructions below) 
1 User’s 

Guide 

1  External AC Power Supply 
1  AC Power Cord (North American Plug) 
 

 

The power cord is the disconnect device. The 
power outlet to which the Duro charger is 
connected must be accessible at all times. 
For permanently installed equipment, (for 
example, installing the charger in a vehicle), 
a readily accessible disconnect device must 
be incorporated into the wiring.

 

 

Installing Adapters 

1. Match the software configuration file name printed on a 
label on the under-side of the charger with the software 
configuration file name printed on a label on the underside 
of the adapter. If the names do not match, please contact 
your representative to obtain the correct adapters. 
2. For larger adapters (figure 1), connect the ribbon cable 
from the adapter to the socket. Then insert the adapter into 
the socket. 
3. Remove the tape covering the screw hole.  
4. Small adapters (figure 2) do not have a ribbon cable: 
insert the adapter into the charger socket. The adapter 
slides into socket in one direction. If the adapter does not 
fit, turn it around and reinsert it. DO NOT FORCE THE 
ADAPTER IN. 

5

. Insert the screw(s) and tighten with a screwdriver. DO 

NOT OVERTIGHTEN. 
 

 

 

Figure 1: For large adapters, 
first connect the ribbon 
cable and then insert the 
adapter. 

Figure 2: For small 
adapters, insert the adapter 
into the socket. 

Operation 

1.  Adapters are color-coded. The text Ni or Li may be 

marked each adapter. 

 

Li-Ion (Li) 

Blue Label 

NiCd & NiMH (Ni) 

Green Label 

Tri-Chemistry (NiCd, 
NiMH and Li-Ion) 

Silver Label 

 

 

NOTICE: 

Attempting to charge a battery with 

the wrong adapter can lead to an incomplete 
charge, battery damage, fire or explosion.

 

Do NOT service

 a Li-Ion battery in an adapter 

with a 

Green label

 or if it is marked 

Ni

Do NOT service

 a NiCd or NiMH battery in an 

adapter with a 

Blue label

 or if it is marked 

Li

.

 

 
2.  Plug the DC output cord from the power supply into the 

back of the charger and the power cord into the wall 
outlet. 

3.  All lights will flash briefly when power is first applied to 

the Duro charger. 

4. If 

 is 

flashing

 

with no battery installed, then an 

incorrect adapter has been installed in this station (ie. A 
high voltage adapter has been inserted into a low 
voltage unit or a low voltage adapter has been inserted 
into a high voltage unit). Please contact your 
representative to obtain the correct adapter. 

5.  Insert a battery. The Duro charger will automatically 

detect the presence of a battery and begin charging.  

6.  If a Li-Ion battery is not detected on the charger, leave 

it on the charger for a few minutes. The charger will 
apply a ‘Boost’ pulse for several minutes in order to 
wake it up.
