Optical signalling of battery discharge status
in the EXTA LIFE application
BATTERY CHANGE
As for usual operation, battery discharge status is signalled by means
of several LED diode flashes during transmission. If the remote control
is paired with a controller, the battery discharge status is indicated in a
mobile application in a form of a displayed message. The remote control
signals the need to change the battery if its voltage decreases to < 2,1 V.
Only after battery change the optical signal disappears.
CAUTION: Substituting the battery with any battery of incorrect
type may cause an explosive hazard. Dispose of used batteries as
stated in the manual.
1. Remove two screws from the bottom part of the remote control.
2. Remove the upper cover with the silicon keyboard.
3. First remove the PCB and then the battery from the latch.
4. Click any push-button for a few times (to discharge its capacity)
5. Mount a new battery. Watch battery polarisation marked on the latch
(“+” potential).
CAUTION: Improper battery mounting can damage
the device!
6. Place again the top cover with the keyboard and tighten the screws.
7. Check the operation – LED diode should switch on in the same way as
during transmission.
