MAINTENANCE
Battery
Charging
Tua Viso is supplied with a 8.4 Volt Ni-MH
rechargeable battery.
The yellow indicator light on the control panel
shows that the battery is undercharged and
is starting to run low. The battery must be
recharged when muscular contraction is
not sufficiently felt or visible. If this happens,
remember to first check the cleanliness
of the sponge domes, as the pulses can be
considerably reduced if they are dirty. If the
sponge domes are dirty, hand wash them
carefully in tepid water using an anti-microbial
hand cleanser and then rinse thoroughly with
clean water or replace them.
To charge the battery (and later to recharge the
battery) you must insert the charger connector
into the appropriate socket next the intensity
regulator wheel.
At this point the display will flash showing the
letter “C” (for “charging”) and the yellow LED
will light up continuously. Once the Tua Viso
battery has finished charging the display will
show the letter “E” (for “end”) and the yellow
LED will turn off, indicating that the charging
process was successfully completed. Next,
disconnect the charger in order to use the
unit. Tua Viso CANNOT be used while it is
charging.
In case you ever need to replace the
rechargeable battery please ensure that you
only ever purchase 8.4Volt Ni-MH 200mAh
rechargeable batteries.
Tua Viso can also work with a normal 9 Volt
alkaline battery (6LR61 type), but in this
case you must not try to recharge it as
this could cause chemical substances
from inside the battery to leak, which is
potentially hazardous.
