YB3i Device Maintenance
Replacing the Battery
Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. The device battery is not user-replaceable; it can only be replaced by your device service provider.
Having said this, the battery in the device should maintain its ability to charge to at least 90% of capacity through 1000 charge cycles. This means that if you charged the unit every day (unlikely) the battery would need to be replaced every 3 years. If you charged the device once a week, it would need the battery replacing once every 10 years. However, you do not need to worry about this issue if you have the unit connected to the yacht’s batteries 100% of the time. With a power draw of only 350 milliamps, your house batteries will only go flat if left unattended for a very long time.
To clean your device use a soft slightly damp cloth to clean any dirt. Do not use alcohol or abrasive substances to clean your device.
If something isn’t working correctly with your YB3i:
Ensure the unit is powered, and any connections in the circuit are good.
Hardware reset the device by swiping the reset magnet all the way around the outside edge of the unit. The unit will beep after about 10 seconds, and will then be reset.
If neither of the above work, then please get in touch with the support team, using the details below.
There is an LED indicator on the bottom of the unit. The LED has the following indicator modes:
Intermittent green flash – running on external power
Intermittent red flash – running on battery
Red/Green alternating – booting up or updating firmware
Off – in shipping mode, stealth mode, or the battery has run out and there is no external power.
