REMARKS:

§If microphone is not “ON” during a communication, the sound on the speaker will be attenuated.

§In standby mode, the microphone will still have a small consumption (less than 1.8 microwatts).

§On some versions, the indicator light will only turn ON for 2 seconds after the microphone is switched ON. If the light is red, this indicates low battery.

§The microphone is activated by the Hands-Free Car Kit base and can remain in “ON” position even if not used. But in order to extend battery life, it is recommended to switch “OFF” your microphone when you won’t use it for a long time.

C.FUNCTION CONTROLS

Adjust the Function Controls as recommended:

1.Tone Control “H” for High Tone “L” for Low Tone.

2.ASP Control

ON =	Echo and Feedback Canceller
OFF =	Echo Reducer only

3.Adjustable Microphone Gain (MIC) Control

“H” for high gain; “L” for low gain.
"L" is necessary in noisy background.	Control Switches
	Figure 4.

The Microphone gain must be adjusted to match with your cell phone model. If the gain is too high, it can cause feedback (whistling sound), echo or background noise during calls on some cell phones.

Recommended Function Controls Setting (Working on all models):

MIC	=	L
ASP	=	ON
TONE	=	H

Note:

On high background environment, If you experience audio level fluctuation, turn ASP ‘’ OFF ’’.

D. SETTING THE VOLUME

There are two volume controls. One is on the main unit. See (4) on figure 1. The other is the volume key of your cell phone. Use the volume control of the Car Kit and the volume keys of your cell phone. Note: If the volume set is too high, it can cause feedback (whistling sound), echo or background noise during calls on some cell phones.
