Otowave 202 Operating Manual
2.3. POWER SUPPLY OPTIONS
The tympanometer is designed for continuous operation and may be powered either by a mains adapter (which
is supplied, and specified as part of the equipment) or optional internal batteries.
Do not connect or disconnect the mains adapter lead while the instrument is operational
as this may cause it to shut down. Always switch off first (see Section 4.3).
Rechargeable batteries must be charged outside of the instrument
– they are not
charged by the mains adapter when this used.
Battery operation
Refer to Section 4.1 regarding the types of battery that may be used and their installation, replacement and
other precautions. Note that local regulations are likely to cover disposal of used batteries.
Mains operation
All other connections must be made before connecting the output lead from the adapter into the POWER
socket on the front face of the tympanometer. Switch on the mains supply - the indicator on the adapter will
illuminate green.
The output from mains adapter is fitted with electronic circuit protection. In case of overload the adapter will
shut down and the indicator will be extinguished. When the fault is cleared the adapter will operate as normal.
The input to the mains adapter is protected with a non-replaceable fuse. If this fails the adapter will not operate.
The mains adapter is the mains disconnect device and therefore the tympanometer should be positioned such
that easy access to the mains adapter is possible.
If a replacement mains adapter is required, please contact Amplivox or your Amplivox distributor.
