<Recharging the battery>
Inserting the power plug of the bed into the outlet starts
recharging of the battery, and recharging will complete
automatically after 12 hours. When using the bed for the
first time, recharge the battery before use.

Normally use the bed with the power
plug of the bed inserted into the
outlet and the battery recharged.

Repeated recharging after the
battery power is used up results in
early degradation of maximum
capacity and a shorter life span.
After battery-powered operation of
the bed, recharge the battery when
possible.

If the indicator shows that the
remaining power is low or
insufficient (see p.38) soon after
starting bed operation, even though
the recharge is completed, it is time
to replace the battery.
<Handling the battery>
Battery life
The battery is not designed to be recharged after the battery power is totally used up. Repeatedly
recharging the battery from zero charge will reduce its battery life. Always recharge the battery after
operating the bed on battery power. If the bed is equipped with a battery and is stored for long periods of
time, the battery must be fully charged every 3 months. Failure to do so may cause damage to the battery
or decrease its life. The battery life will vary depending on the usage frequency, usage conditions and
storage conditions. Regardless of whether the battery is used, its life will start to decrease after a few
years.
Check regularly whether the bed can be battery-operated or whether the battery
replacement time has been reached. Replace a battery that has reached the
replacement time.
Storage
The battery self-discharges slightly. When storing the bed, recharge the battery for 12 hours or more, and
disconnect the power plug of the bed. Do not press any of the operating buttons during storage as
pressing the buttons will cause the bed to switch from the power-saving mode to the normal mode, which
uses the battery power. If any of the buttons are pressed and the LED indicators (e.g., battery status
indicator LED) turn on, reconnect and then disconnect the power plug to save power and prolong the time
that the battery can last. This reduces the impact of excessive discharge on the battery life. Note that it is
recommended to store the bed at an ambient temperature of 25˚C. When storing the bed for a long period
of time, recharge the battery for 12 hours or more once every 3 months. If the battery is not recharged, the
battery may deteriorate or the battery may become no longer rechargeable. Recharging the battery
automatically turns the power supply on.
