CHARGING THE SMART REMOTE
We recommend charging your Smart Remote for one hour
before using it the first time. No damage occurs if it is used
before being fully charged. You can use the remote while it
is charging.
The status display shows the remote's battery level while the
remote is powering on or charging.
Note: When the remote is searching for a camera, the battery drains faster. If you are not using the remote
during charging, be sure to turn it off to conserve battery power.
