Some Basic Facts on Battery Power
TONOPORT VI is either powered by two rechargeable 
nickel-metal hydride batteries (NiMH) or by two alkaline 
batteries. The device must be set to the power source used 
(see section "Inserting Batteries"). The device also 
contains a Lithium cell that powers the clock. The 
Lithium cell can only be replaced by a service technician.
The capacity of two fully charged or new batteries is 
sufficient for up to 400 blood pressure measurements.
The capacity of rechargeable batteries decreases with 
age. If the capacity of fully charged batteries is 
considerably less than 24 hours, the batteries must be 
replaced.

Caution
Equipment Damage—
– Only use the original rechargeable, size AA nickel-
metal hydride batteries (from manufacturers such 
as Sanyo, Panasonic, Energizer, Duracell, Varta, 
GP) with a capacity > 1500 mAh or high-rate 
discharge, size AA alkaline batteries (such as 
Panasonic Evoia, Energizer Ultimate, Duracell 
Ultra, Duracell Power Pix, Varta maxtech).
– Charge the NiMH batteries to capacity before 
using them for the first time.
– Recharge the NiMH batteries immediately after 
use and do not leave batteries uncharged.
– Use only the original charger to recharge the 
NiMH batteries.
– Do not attempt to recharge alkaline batteries.
– If TONOPORT VI will not be used for one month 
or more, remove the (rechargeable) batteries from 
the device.
– Batteries must not be disposed as unsorted 
municipal waste and must be collected separately. 
Please contact an authorized representative of the 
manufacturer for information concerning the 
decommissioning of the batteries.
