Low battery warning
When you see the left and right indicator
lights blink alternating blue and red for two
seconds, your Smart Control is warning you
that the battery in your remote is low. You will
see the warning every time you turn on your
Smart Control or send a command to your
hearing aids until you change the battery or
the battery dies.
Caring for batteries
Always discard batteries in a safe and
environmentally friendly way
To prolong battery life, remember to turn the
remote control off when not in use
