Always dispose of old equipment correctly – keep our environment tidy

Old electrical and electronic equipment marked with this symbol can contain substances hazardous to human beings and the environment. Never dispose of these items together with unsorted municipal waste (household waste). In order to protect the environment, public collection points have been set up to ensure the correct disposal of old electrical and electronic equipment marked with this symbol.

To reduce the risk of these substances being released into the environment and to reduce the burden on natural resources, it is also possible to participate in Avaya's used equipment return system. This system ensures the correct recycling of old equipment as well as the reuse of individual components.

Tips on phone location

Place the telephone on a non-slip surface, especially if the furniture is new or has recently been cleaned or polished. Varnishes or cleaning agents may contain substances which soften the base parts of your telephone, and softened bases can leave undesirable marks on furniture. Avaya cannot assume liability for damage of this kind.

Repairs

The equipment may only be opened or repaired by a qualified technician. Do not open the telephone yourself. Doing so could damage the unit and cause it to malfunction.
