9.10 Cleaning and disinfecting your telephone
This chapter provides guidelines for cleaning or disinfecting Alcatel-Lucent Enterprise terminals to protect
products and optimize performance. The final result will depend on each user's personal procedures, for
which ALE cannot be held responsible.
• Wear gloves when cleaning products.
• Do not use harsh chemicals such as bleach, peroxide, acetone, ethyl acid, methyl chloride,
ammonia, or multi-purpose cleaners to clean plastic, metal, rubber, or screen surfaces.
• Wipe products with a clean, dry, microfiber non-abrasive cloth.
• Spray cleaning solution on the cloth before cleaning the product.
• Use pre-moistened wipes or dampen (but do not wet) a soft sterile cloth with the approved agent.
Never spray or pour chemical agents directly onto the device as the liquid may stain the product or
seep inside and damage the hardware.
• Do not allow liquid to pool.
• ALE recommends using a 70% ethanol solution for all wired and wireless ALE terminals.
• Daily disinfection: Up to 5 disinfections per day.
• Extensive wiping during cleaning or disinfection may cause surface damage to the device.
• ALE recommends assigning a dedicated wireless terminal to each employee rather than sharing
shifts on terminals, as well as replacing the handset on wired terminals for each employee.
