User's Manual

While Honeywell equipment is manufactured and tested to be resistant to normal dirt and deposits from the
workplace environment, the build-up of residue can damage the equipment and degrade performance over
time.
• Dirt or corrosion can prevent the proper seating of terminals in chargers and may cause intermittent
charging.
• Talkman
®
Connector (TCO) contacts that build up dirt, chemicals, and corrosion may cause intermittent
contact, static, and recognition problems.
• Excessive dirt on a keypad membrane can cause the membrane to weaken and tear.
Caution: Use only a solution of 70% isopropyl alcohol and water to clean equipment. Other products
have not been tested and may degrade the equipment.
Cleaning Plastics
Cleaning Hard Plastics
Clean the hard plastics on headsets, devices, chargers, and batteries with a soft cloth that is wet with a
solution of 70% isopropyl alcohol and 30% water.
Use a soft brush to keep the pocket areas of chargers free of dust and debris that may interfere with the
seating of equipment or electrical contact.
Cleaning Foam and Pliable Plastics
Clean headset foam parts (ear pads and headband pads) as well as flexible bands and non-foam padding
with a mild soap and water. Wash pads carefully so as not to tear or detach them.
Air dry the parts. Use of a concentrated heat source such as a hairdryer or clothes dryer is not recommended.
Replace pads that are excessively dirty, such as headset windscreens.
Cleaning Contacts
Clean flat contacts on the device, such as the Talkman Connector (TCO), or flat contacts on the battery and
charger with a 70% isopropyl alcohol solution.
Use a soft, lint-free cloth or premoistened alcohol wipe. Avoid using a cloth with long or thick fibers as the
fibers can attach to the connectors and cause intermittent contact.
Remove corrosion with a soft eraser (for example, a pencil eraser). The eraser must be in good condition
(soft, pliable, and not worn down to the mounting). A good test is to rub the eraser against your skin. If it feels
abrasive, do not use it, because it will damage the surface of the connectors.
You can also use a three-row cleaning brush with natural hog hair bristles to gently brush away dirt on the
contacts. A final alcohol wipe after this should ensure a clean contact.
Never bend or manipulate battery contacts.
Contact an authorized Vocollect Service Center to repair or replace contacts that are extremely corroded,
bent, or missing.
