SETP 5: Set up RF Power
The ankle bracelet RF transmit power can be set for Home Unit curfew range adjustment.
There are totally 8 levels of RF transmit power that can be set. The stronger the RF transmit power is, the wider
the curfew range would be. We always adjust the level of RF transmit power for both the bracelet and Home
Unit.
RF channel defines that all the equipments including NB5 (bracelet), HU3 (Home Unit) should use the same
channel to communicate each other. In some case there are a number of set of equipments in the same place
(such as more than 10 sets), we can set them in groups and configure each set to different channel, and it will
reduce the possibility of disturbing each other.
Generally we don’t have to change the default channel.
