Put the handset on the base unit. The red Charge LED 
will lit as long as the handset is on the base.
Charge the handset for a period of 24 hours before using the handset for the first time. To extend the battery life time, discharge the batteries completely from time to time. As soon as the handset emits a warning tone or when the battery icon 
is empty, you have to put it back on the base unit for charging.
4. BATTERY LOW INDICATION
When the battery is empty, the handset no longer carries out operations. When a battery is completely empty and you have put the handset on the base unit for a short period of time, the Battery symbol will appear to be fully charged but this is actually not the case. The battery capacity will decrease rapidly. We advise you to put the handset on the base unit for 12 hrs so that it can be recharged completely.
