Product Description
LTD104 PC based portable clinical audiometer
The LT D104 is a new portable diagnostic audiometer using state of the art. The Liquid Crystal Diode (LCD’s) on the display panel tells you the options you have selected. The Pure Tone has been derived using crystal controlled digital oscillator, meaning you can stop worrying about frequency shifts and recalibration.
Puretone is processed using narrow band filters, which reduces harmonic distortion to negligible levels.
The OPERATING MANUAL makes you familiar with various salient features this equipment offers. To get the maximum out of this manual, keep your LTD104 in front and go on operating the equipment as manual tells you to.
Any wrong step or deviating from the step as given in the manual will not in any way damage the equipment.
To sum up, you are in for a new light-weight experience in diagnostic audiometry. With the clear instructions that are given in this manual, you will find it easy to learn operating the LTD104 DIAGNOSTIC AUDIOMETER.
