max. 70% alcohol
0,5% Chlorhexidine in 60% alcohol

disinfection, other than that carried out during the rapid heating of the Larynx Mirror,
could cause destruction or degradation of parts and should only be carried out at the
user's own risk.
The Type 4914 is equipped with a powerful thermostat-controlled fan which maintains
acceptable temperatures inside the instrument even with high ambient temperatures and
when the instrument is used to its full capacity.
The fan will only operate if the either of the Lamps heats the Lamp Housing to a tempe-
rature of the order of 50 to 60
°c.
Since most users only use the Lamps for short
periods of time, the operation of the fan is likely to be infrequent.
Note: The air vents on the side and rear panels of the instrument should be kept clear at
all times.
When the fan is operating, it will continue to circulate air even after the Lamps are
switched off until the Lamp Housing is cooled to an acceptable temperature.
Note: In a hot climate the ambient temperature may be so high that the thermostat will
not switch the fan off again once it has been switched on.
