■ Desk (see Desktop Mounting below ) ■ Wall (see Wall Mounting below ) See the phone's Quick Guide shipped with the device and also available from AudioCodes for detailed information on how to mount the phone. See also here f or a clip showing the principle of how to mount an AudioCodes IP phone. The principle is the same across all AudioCodes IP phones. Desktop Mounting The following documentation shows how to mount the phone on a flat surface like a desk. ➢ To mount the phone on a flat surface like a desk: Off-hook the handset (if on-hook) and place the phone upside down, i.e., base-up, on your desktop. On the phone's stand, identify outer notches.
➢ To mount the phone on a wall: Attach the stand of the phone for the purpose of a wall mounting: Detach the base. Attach it again as you did for a desktop mounting (see Desktop Mounting on the previous page ) only now make sure that it's flatly aligned to lie flush against the wall, i.e., slide the inner rails of the phone stand onto the phone base's inner notches. Connect the AC power adapter, LAN and PC/laptop cords. In the wall, drill two horizontal holes at a distance of 4 7/8 inches (123.8 mm) from one another, in line with the template. Insert two masonry anchors into the holes if necessary. Thread two screws (not supplied) into the two masonary anchors; ensure that the heads extend sufficiently (about 3/16 inch or 5 mm from the wall) for the phone stand's keyhole slots to hang on. Hang the phone stand's keyhole slots on these screws. Before Using AudioCodes Devices AudioCodes recommends frequently cleaning devices' screens especially screens on devices in common use areas such as conference rooms and lobbies. ➢ To clean a device's screen: Disconnect all cables. Spray onto a clean, dry, microfiber duster a medicinal isopropyl alcohol and water solution of 70:30. Don't oversaturate the duster. If it's wet, squeeze it out. - 18 -...
