* Typical values.
There will be an audible tone beep repeated every 80 seconds when batteries are low.
The terminal voltage of alkaline batteries recovers when the batteries are not in use. The remaining time prediction is
thus unreliable during the first period after power on. Nearly depleted batteries may still be able to provide a voltage
above the threshold for battery low indication, even if the internal battery resistance is too high to provide sufficient
current to start up the device next time the power on button is activated.
To extend battery life time the Radius PCG display has an automatic brightness control, which will be activated during
stable conditions. Any change in displayed vital parameters, alarm or pressing any button will return the Radius PCG
display to normal brightness.
