Software updates
Unlike consumer-grade Android phones, your administrator manages software updates of both the phone
version and of the apps.
• If the administrator sees that your phone software is out of date, they may be able to force an update. A
forced update closes all active applications and reboots the phone.
• If the administrator updates an app version, you may notice that app features change without warning.
These changes in the app occur because only one version of an app can run at a time.
Apply software updates
Periodically, your phone connects to a server and downloads an available software update. If your administrator
doesn't set your phone to automatically reboot after a software update, you receive a notification to reboot
your phone. When you tap Reboot, your phone automatically closes all active applications and reboots the
phone. You may defer the reboot for a set amount of time.
When the phone connects with the server after the update, the server identifies that the phone update is
complete.
Procedure
Tap Reboot.
Care of your phone
Your phone is rugged and made for use in tough environments. It’s built out of strong and resilient plastics.
All components are durable and reliable.
We’ve extensively tested the phones and warranty them for normal use under rigorous conditions. The Cisco
Wireless Phone 840 has an IP65 rating and the Cisco Wireless Phone 860 has an IP68 rating. However,
accidental, or inadvertent exposure to various substances can cause the phone to perform poorly or fail
completely.
There are many substances that you can’t clean off without damaging the device beyond repair. For instance,
if you drop your phone into glue or paint, even if you carefully clean the phone, it may not function properly.
Also, oil-based substances, such as make-up or lotion, can leave a sticky residue on the phone that attracts
and binds particles. This can jam key components such as the camera, microphone, speaker, or headset jack.
We don’t cover damage from such conditions under warranty. You can prevent or remedy such damage
through careful use and proper care and maintenance.
There are no serviceable parts in the phone, batteries, or chargers. Don't open or disassemble the phone case,
battery, or charger. You void your warranty if you disassemble any of these items.
