according to the UN 38.3 transport regulation for
lithium-ion batteries.
• Misuse or improper use could damage the battery. In
extreme cases, there is a risk of explosion, heat, fire,
smoke or gas.
• Never expose the battery to excessive heat such as
sunshine, fire or the like.
• Do not expose the battery to mechanical shock.
• Charge the battery before initial use.
• Use the specified chargers for charging the battery.
• Avoid complete draining of the battery. This could
damage the battery and shorten its service life.
• If you do not use the transmitter for several months,
the batteries should be charged at least twice a year
to prevent deterioration in performance due to self-
discharge.
• Clean the charging contacts of the transmitter with a
clean dry cloth, if they become dirty.
• Do not short-circuit the battery.
• The charging contacts could cause property damage,
injuries or fire damage if they come into contact with
conductive materials such as jewellery, keys or chains.
This can lead to a closed electric circuit and, therefore,
to the material overheating. To avoid this kind of
unintentional electric circuit, the charging contacts
must be handled with care. This is especially important
if the transmitter is transported in a bag or another
container containing other metallic objects.
Moisture / heat sources
• Keep the battery clean and dry. Never expose the
device to rain or high humidity. Do not install it in the
immediate vicinity of swimming pools, shower
facilities, damp basements or other areas with
unusually high air humidity.
• Never place objects filled with water (e.g. vases or
drinking glasses) on the device. Liquids in the devices
may cause a short circuit.
• Never install or operate the device in the immediate
vicinity of radiators, lighting systems or other heat-
generating devices.
