Charging the doseBadges

 

 

Please note that this manual refers to the CU:110A Charger Unit only. The 

information given does not apply to any previous version of the CU Charger 

Units. The CU:110A is identified by a Black Case with the older charger units 

having a White Case. 

 

The CU:110A Charger Unit has a maximum charge time of 2½ hours. If the doseBadge 

is not fully discharged, the charge time will be shorter than this. 

 

It is essential that this procedure is carefully followed otherwise damage will occur to 

the doseBadge battery. 

 

Before using the doseBadges for the first time, ensure that the units are allowed to 

charge fully. The doseBadges should be regularly recharged to maintain the 

performance of the battery pack (inside the doseBadge) 

 

For further information regarding the charging and maintenance of the doseBadge, 

please refer to Page 38 “Maintenance & Care” 

 

Connect the Charger to the mains power supply and switch on the power supply. 

 

Ensure the doseBadge is in Stop Mode and carefully screw it onto the "charging stud" 

on a CU Series Charger unit.
