in your phone, or you may have to install it yourself.
You must read the safety information in
charge the phone.
The battery may already be charged using one of the supported charging methods. If the battery isn't charged,
you must charge the battery before you can set up the phone.

Install the Phone Battery

IP67 compliance means that the phone is sealed from dust and water. When the phone leaves the factory, it
is completely sealed.
If you need to open the battery compartment, don't open it in a dusty or wet environment.
You should make sure that the battery cover is closed to ensure that dust and water cannot enter the battery
compartment.
Note Dirt, oil, or other products can damage the gasket on the battery compartment cover, resulting in a poor
seal. Every time you change the battery, inspect the gasket for damage. If the gasket is damaged, you can
order a replacement cover.
