6.1 Operating and maintenance notices
NOTE
If the product is stored at a temperature above 50 °C, or is not used for an extended
period of time, the batteries must be removed. Leaks from the batteries are avoided as
a result.
NOTE
The electrode should be stored in dry rooms at a temperature between 10 °C and 30
°C. If the storage temperature range is exceeded or undercut, the electrode can be
destroyed. It should always be stored wet in distilled or deionised water.
6.2 Battery
6.2.1 Battery indicator
If the empty frame in the battery display blinks, the batteries are depleted and must be
replaced. However, the device will still operate for a certain length of time.
If the
BAT
display text appears in the main display, the battery voltage is no longer ad-
equate for operation of the product. Now the battery is fully depleted.
6.2.2 Changing battery
DANGER
Danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batter-
ies to crack and possibly explode!
– Only use high-quality and suitable alkaline batteries!
CAUTION
Damage!
If the batteries have different charge levels, leaks and thus damage to the product can
occur.
– Use new, high-quality batteries!
– Do not use different types of batteries!
– Remove depleted batteries and dispose of them at a suitable collection point!
NOTE
Unnecessary screwing places the water-tightness of the product, among other things,
at risk and should be avoided.
