Maintenance
– If the headphone will not be used for a longer time,
please remove the batteries to prevent leakage and
corrosion.
– Only replace the batteries with R03/AAA NiMH
batteries (preferably Philips).
– Do not leave the headphone near heat sources. Do
not expose to direct sunlight, excessive dust, moisture,
rain or any kind of mechanical shock.
– Do not use alcohol, thinner or petroleum-based
substances to clean the headphone or transmitter. Use a
slightly dampened chamois cloth to clean the housing.
– Do not use cleaning agents containing alcohol, spirits,
ammonia or abrasives as these may harm the housing.
