Although the shaver, trimmer can be used for a set period
after a full charge that number is assuming dry-shave usages
for 3 minutes per day, the usable length of time might be lower
depending on how the product is used (for example, when used
for wet shaving or extended use.).
When the number of operations per charge starts to
decrease, the battery is nearing the end of its life. Please
contact a service repair center authorized by Panasonic for a
replacement if applicable. Refer to HOw to replace the battery to confirm if it can be replaced
When shaving make sure the appliance is not pressed against
your skin too hard. Contact to skin with gentle force.
