7 . 5. MAINTENANCE
You can clean external surfaces by soft, slightly damp cloth. Never use abrasive chemicals or water for this purpose. Don’t
try to disassemble your motorized cylinder.
7.5.1. C HARGING YOUR MOTORIZED CYLINDER
If you hear three short tones after operation of the motorized cylinder or if the rotation speed is too slow compared to
normal working speed, you need to charge your motorized cylinders. For this purpose, we recommend to use provided
charger and cable.
! ATTENTION !
- Charging period of your device is around 3 hours. We recommend you to charge it under supervision.
- With your own risk, you can use any 5 V DC microUSB chargers or a powerbank. Use high quality chargers, cables and
powerbanks only.
- You may use your motorized cylinder as it is always connected to charger. The device will automatically adjust itself to
work as always connected. (valid for firmware version 72 and higher.)
- If you are leaving your home for an extended period of time, first fully charge your motorized cylinder and take your
mechanical key with you. If you would leave more than 2 months, after charging your motorized cylinder, either shift the
motorized cylinder to childlock mode or leave your device as it is connected to charger. Otherwise, the batteries of your
product would die due to deep discharge.
