5. BATTERY REPLACEMENT

• 1,5V Alkaline AA type batteries can be used. Install only new, high quality
and unexpired batteries. Do not mix the old batteries with the new ones.
• At least 1 battery must be removed if the device is not in use.
• In order to avoid fire or explosion hazards, the system must be used only
with approved battery. Special care must be taken when connecting posi-
tive and negative battery terminals. Dispose old batteries only into special
collection sites. Do not charge, disassemble, heat or incinerate old batteries.
• The battery status can be monitored in real-time using ELDES Configura-
tion Tool software.
• The system sends an SMS text message to the listed user phone number
as soon as the battery level runs below 5%.
• EW2 does NOT feature a built-in battery charging unit, therefore only 1,5V
Alkaline AA type (non-rechargeable) batteries can be used.
