AT&T MERLIN 410 Installation Manual page 5

Check the items in your shipment against your copy of the order form.
Make sure the items and quantities agree. Save the instructions packed
with components; you may need to refer to them later. And keep the pack-
ing boxes just in case you have to return components under warranty.
Get acquainted with the system environment.
Review the planning sheets you drew up when you ordered the system.
Confirm the voice terminal locations, and make sure the control unit loca-
tion meets the following environmental standards:
— Operating temperature: 40-104°F (4-40°C)
— Humidity: not to exceed 80%
— Ventilation: Leave 6 inches of space above and to the sides of the con-
trol unit to prevent overheating. Keep the control unit away from sources
of extreme heat (furnaces, heaters, attics, or direct sunlight). Do not
stack multiple control units in rooms that are not air-conditioned; in-
stall them side by side at least 6 inches apart.
— Airborne contamination: Do not expose the control unit to moisture, cor-
rosive gases, dust, chemicals, or similar substances.
If your control unit location does not meet these standards, your warranty may
become void.
