2.3 - Batteries
This unit is equipped with a CR 2430 type 3V lithium battery.
- Match the +/- polarity
- The batteries supplied are not rechargeable
Warning : there is a risk of explosion if the battery is replaced
with the wrong type. Dispose of used batteries in accordance

Safety guidelines
These instructions must be read carefully and observed. Keep this
manual.
Hazard for children
• Batteries could pose a lethal risk if swallowed. The remote
control and its batteries must be kept out of the reach of
young children. If a child does swallow a battery, seek
medical attention immediately.
• Keep the packaging out of the reach of children. Risk of
su󰀨ocation!
Risk of injuries and health problems
• If the liquid acid leaks or becomes oxidised, avoid any contact
with the skin, eyes and mucous membranes. In the event of
contact with battery acid, rinse the point of contact
immediately with plenty of clean water and seek medical
attention immediately.
• Batteries should be removed from the unit when they are
spent, or if they are not being used for prolonged periods.
This will prevent damage due to leaks.
• Do not expose the batteries to extreme conditions by placing
them on radiators, for example. Increased risk of leaks!
• The batteries must not be charged, opened, thrown into re
or short-circuited. Risk of explosion!
Battery recycling
• Do not dispose of batteries with the ordinary household
waste. To protect the environment, batteries should be
disposed of in line with the regulations in force.
