Operation

Installation and battery charging

NOTE

- Useful life for the battery used

for the operating table is about

2 years. Once it reaches the

useful life, ask your distributor

or us for battery changing.

- Battery life will vary greatly

depending on the operating

conditions. The battery may

deteriorate quicker if charge

and discharge of the battery

are repeated frequently after

using the operating table for a

short time. It is recommended

that you charge the battery

once a week (on weekends),

since it takes 10 hours for the

battery to be fully charged.

- Even after the battery is

charged, in case that all

the battery indicators do

not come on, or the battery

gets discharged soon, the

battery may get deteriorated.

Ask your distributor or us for

repair.

- You can operate the operating

table using the power ON/

OFF switch while the battery

is being charged.
