Error Messages
In the unlikely event of your product developing a problem,
“Err” will appear on your controller display (Fig. d). If this
occurs you should switch the controller off and then switch
it back on again. It should now operate properly. If the
problem persists, please call
SLENDERTONE
Customer Care
for further assistance (see page 2).
Battery Power / Replacing the battery
The battery icon on the display will flash when the battery
is low and needs to be recharged. After a period of time,
you may find that your battery will only power your
controller for a limited number of sessions, requiring you
to charge the battery more frequently. This is because
rechargeable batteries have a limited number of charge
cycles and may eventually need to be replaced.
Should you need to replace the rechargeable battery,
remove the small rubber plug from the back cover of
your controller (Fig. e), unscrew the back cover and
remove it. Replace the existing battery pack with a new
battery pack (Fig. f ) and replace the battery cover. You
can purchase a new battery pack from the website or
by contacting
SLENDERTONE
Customer Care.

BATTERY CHARGING AND DISCHARGING
Your controller is powered by a rechargeble battery. The full performance of a
new battery is achieved only after two or three complete charge cycles (fully
charged and discharged).
The battery can be charged and discharged hundreds of times, but it will
eventually wear out. To ensure optimum battery performance you should use
your product regularly e.g. perform 1 session a day, 5 days per week. Use the
battery only for its intended purpose. Never use any charger or battery that is
damaged.
If a replacement battery is being used for the first time or if the battery has not
been used for a prolonged period, it may be necessary to connect the charger
and then disconnect and reconnect it to start the charging. If the battery is
completely discharged, it may take a few minutes before the charging indicator
apperas on the display.
Unplug the charger from the electrical socket and the controller when it is not in
use. Do not leave a fully charged battery connected to a charger, since
overcharging may shorten its lifetime. If left unused, a fully charged battery will
lose its charge over time.
Leaving the battery in hot or cold places, such as in a closed car in summer or
winter conditions, will reduce the capacity and lifetime of the battery. Always try
to keep the battery between 15°C and 25°C (59°F and 77°F). A product with
a hot or cold battery may not work temporarily, even when the battery is full
charged. Battery performance is particularly limited in tempertaures well below
freezing. Do not dispose of batteries in a fire as they may explode. Batteries
may also explode if damaged. Dispose of batteries according to local
regulations. Please recycle when possible. Do not dispose as household waste.
