Troubleshooting
Charging with the Charger
Cable
Q1
The watch won't charge with the
charger cable.
Is the end of the charger cable with the
special watch connector securely aligned
with the watch charger terminal?
Charging may fail if there is space
between the terminals.
Precautions When Charging
l
Did you leave the watch attached to the
charger cable after charging was
complete?
Charging stops automatically after the
watch becomes fully charged. If you want
to charge again, unplug the charger cable
from the watch and then re-attach it.
Is charging still impossible after checking
the above points?
Check to make sure that the USB device
or power source is functioning normally.
Q2
Charging stops before it is complete.
Charging may stop if some temporary
abnormality occurs. Unplug the charger cable
from the watch and check for abnormalities. If
there is nothing wrong, try charging again.
If the above does not eliminate the problem,
contact your original retailer or a CASIO
service center.
I can't pair the watch with a
phone.
Q1
I've never been able to establish a
(pairing) connection between the
watch and phone.
Are you using a supported phone model?
Check if the phone model and its
operating system are supported by the
watch.

models, visit the CASIO Website.
