2.4 Charging checking
Use the BLL–3 battery and the JBE-2 calibration unit to test charging.
When you are charging totally empty battery, remember that start–up charging
might take 2 minutes with ACP–9 charger and several minutes with ACP–7
charger.
During this time display is blank. If charger is not NMP approved type and sup-
ported by phone then the software doesn’t start charging and display ’NOT
CHARGING’.
Remove and reconnect battery and charger few times before you start to mea-
sure module. This check ensures if module fault really exists.
See the diagram Figure 11 next page.
