Storage

● 

Short-term storage (up to several days): Turn off your 

device via the push button or place it in the powered 

charger.
The charger must be connected to the power supply. 

If the charger is not connected to power supply and 

you place your device in the charger, the device is not 

turned off.
Note that when you turn off the device via a remote 

control or smartphone app, the device is not turned off 

completely. It is in standby-mode and still draw some 

power.

● 

Long-term storage (weeks, months, ...): First, fully 

charge your device. Turn it off via the push button 

before storing it. We recommend using drying products 

while storing the device.
At 6 month intervals you will have to charge the device 

to avoid an unrecoverable deep-discharge of the 

power cell. Deep-discharged power cells cannot be 

charged anymore and they have to be replaced. We 

recommend recharging more frequently than 6 month 

intervals.
Observe the storage conditions in section 

“Operating, transport and storage conditions”.
