8.5 Changing the Battery
Querx is fitted with a battery that is used to operate the
internal clock in the case of a power shortage. A notification
appears in the lower left corner of the web interface if the
battery's charge reaches critical levels.
The battery can be changed as detailed in the following
section. However, we recommend sending the device in for
maintenance.
⚠
Information
Querx is operational without a battery. The battery does
not need to be changed if the device is in ongoing
operation under normal operating conditions (at a
temperature of approx. 23 degrees centigrade). The
battery should be changed every five years if the device is
not connected to a power source, e.g. during storage.
In order to change the battery you will need:
Two Phillips screwdrivers, sizes PH0 and PH1
A replacement battery, type Renata CR1225
⚠
Attention
Take care not to touch any electrical contacts while
changing the battery. Electrostatic discharges (ESD) can
damage the device immediately or in the long run.
