Using HDA 300
1. Ask the test person to remove glasses, earrings or any other items that might keep
the headphones from fitting properly.
2. Place the headphones on the test person with the red ear cup on the right ear.
3. Adjust the headphones so that the ears are completely inside the ear pads.
The test person should feel even, gentle pressure around their ears and the headband
should fit closely to the head.
The headphones are in constant contact with the patient, and should therefore be kept
clean. See the cleaning instructions in Cleaning ► 7.

Storage and Handling
6
•
Do not store the headphones in a position that straightens the headband. If the headband is straightened, it can lose elasticity, and the pressure of the headphones against
the ears can be reduced.
•
Do not position the headphones so that someone is likely to trip over the cable.
•
Do not twist, bend, or damage the cable. Accidental damage and incorrect handling
can have a negative effect on the functionality of the device. Contact your supplier
for advice.
