Cleaning the Cisco Unified IP Phone

To clean your Cisco Unified IP phone, use a soft, dry cloth to wipe the phone and the touchscreen. Do

not apply liquids or powders directly on the phone. As with all non-weather-proof electronics, liquids

and powders can damage the components and cause failures.

Disable the touchscreen before cleaning it so that you will not inadvertently choose a feature from the

pressure of the cleaning cloth. To disable the touchscreen so that it will not respond to touch, press the

Display

button for more than one second. The phone displays Touchscreen Disabled and the

Display

button flashes green.

After one minute, the touchscreen automatically re-enables itself. To re-enable the touchscreen before

that, press the flashing

Display

button for more than one second. The phone displays Touchscreen

Enabled.

Conceal Ratio and Conceal

Seconds increase significantly

•

Network impairment from packet loss or high jitter.

Conceal Ratio is near or at zero,

but the voice quality is poor.

•

Noise or distortion in the audio channel such as echo or audio

levels.

•

Tandem calls that undergo multiple encode/decode such as calls

to a mobile network or calling card network.

•

Acoustic problems coming from a speakerphone, handsfree

mobile phone or wireless headset.

Check packet transmit (TxCnt) and packet receive (RxCnt) counters

to verify that voice packets are flowing.
