LED flashes green: at half charge
LED flashes red: very low – replace
You hear in the CT communication set three (3)
low beeps in 30-second
intervals
Undser heavy load and high volume and depending on the battery/storage battery
status the communication may result in a distortion-like audio impression. This is
normal and prevents system crashes / malfunctions if a battery / storage battery
does not provide enough power anymore. An acoustic warning signal advises if
the battery / storage battery is almost flat.
Remedy:
Reduce slightly the volume or change the battery / storage battery.
The button does not disconnect if the battery/storage battery is dead, in order to
enable the user to communicate even in critical situations where a battery change
is not possible.
