Question
Some buttons do not seem to
work when I press them.
What do I do wrong?
I place the parent unit in the
charging base (B-15) but the unit
doesn’t function.
Operating time of the parent
unit batteries is supposed to be
at least 8 hours. How come the
battery operating time of my
parent unit is less?
Frequently asked questions
Answer
Except for the On/Off buttons (A-1, B-6), only press the
buttons briefly.
When the batteries of the parent unit are low, you have to
wait for up to 20 minutes after placing the unit in the charger
before the unit starts functioning.
When the parent unit batteries are charged for the first time,
operating time will be less than 8 hours.The batteries will use
their maximum capacity after at least four times charging and
discharging.
Maybe the volume setting is too high.When the volume is set
to a high level, the unit consumes more power. Set the volume
to a lower level (B-10).
Maybe the microphone sensitivity setting is too high.When
the sensitivity is set to a high level, the unit consumes more
power. Set the sensitivity to a lower level (B-10).
When the set maximum temperature is lower than the room
temperature, the unit consumes more power because the
display is continuously lit.This is also the case when the set
minimum temperature is higher than the room temperature.
