7. Maintenance
7.1 Care of the Battery
The battery should be completely charged before it is used for the first time. Note that the maximum capacity of the battery
is not attained until after approx. 5 - 6 charging and discharging cycles.
As the battery power diminishes over the course of time, the batteries should be completely discharged and recharged
every now and then in order to retain the full capacity. For that purpose the devices are left switched on until the devices
switch off themselves. Then recharge the battery completely outside the Ex zone.
Before a lengthy idle time it is essential to charge the battery completely and to recharge it regularly (every 3 months).
7.2 Cleaning the Battery Contacts
■
Check the battery contacts and the battery compartment regularly for:
- rust, dust deposits and dirt
■ To clean the contacts, use e.g. a rubber eraser, contact spray, cotton buds or a dry cloth.
■ Avoid using water or chemical agents for cleaning
