Using Headsets In Freezer Environments; Cleaning Windscreens - Honeywell A700 Hardware Reference Manual

Always use pads and windscreens with Honeywell headsets to protect the equipment and
l
ensure optimum speech recognition performance.
Honeywell recommends changing headset windscreens every 90 days to ensure the best
l
performance.
CAUTION
Use only a solution of 70% isopropyl alcohol and 30% water to clean the hard plastics on
equipment. Other products have not been tested and may degrade the equipment.

Using Headsets in Freezer Environments

Honeywell recommends the following best practices for optimal speech recognition
performance when using headsets in freezer environments.
Train your voice templates in the freezer environment. If operators train templates in a
l
quiet area, the noise of a freezer could disrupt recognition.
Position the microphone as close to your mouth as possible, but outside of your breath
l
stream. It should be facing your upper lip, and not touching anything (for example,
clothing, skin, or facial hair).
Keep windscreens dry. Water will not damage the equipment; however a windscreen can
l
create a water barrier that degrades speech recognition.
Do not attempt to break ice from a windscreen. The pressure can grind ice into the foam
l
and cause a water barrier as it melts. Ice build-up generally does not degrade performance
because Vocollect's Adaptive Speech Recognition compensates for gradual changes in the
environment.
Replace a windscreen if liquid or ice on the foam is accompanied by significant problems
l
with recognition.
If the headset plays a "headset maintenance is needed message" when used in the freezer
environment, contact your support representative for information. Do not return the headset to
Honeywell unless directed to do so by your representative.

Cleaning Windscreens

Honeywell recommends that you change windscreens every 90 days for optimum speech
recognition performance. By protecting headset microphones, windscreens prevent the
accumulation of dirt which can reduce the clarity of operator responses.
IMPORTANT
Soap, cleaning solutions, and vigorous washing will remove the protective coating on the
windscreen and decrease its effectiveness.
1. Remove the windscreen from the microphone.
2. Rinse the windscreen under warm water.
