When your Parent Unit is removed from the AC Adaptor and in Video + Sound Mode the rechargeable batteries will last approx. 4.5 hrs:
- When the Parent Unit has the video display constantly ON and/or also using continuous sound transmission (search for VOX info) as with all cordless devices this will naturally drain the re-chargeable batteries when it is not connected to power
- In addition to this the amount of noise in each home is different, therefore as the Parent Unit is constantly transmitting background noises, music etc. these will also drain the battery power in this unit
When the Parent Unit is removed from AC Adaptor and in Screen Save + Sound Mode the rechargeable batteries will last approx. 5.8 hrs:
- It is recommended that should you wish to use the Parent Unit for longer periods of time and/or using continuous sound transmission (search for VOX info) that you keep the Parent Unit plugged into the power
This is indicative of any portable device (such as your mobile phone) that constantly streams information, video etc. These function use more power that when any unit is standby/power save mode.
