1.3 Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS.
DO NOT DISCARD, READ BEFORE OPERATING
GENERAL
Exercise extreme care when handling any electronics equipment as it
contains precision parts that can be damaged by improper handling.
Avoid touching connector pin surfaces. Foreign matter deposited on contact
surfaces can cause corrosion, and eventually lead to degradation of
performance. In addition, do not use abrasives to clean contact/pin surfaces.
FIRE
For continued protection against risk of fire, ensure that only the specified
fuse type and rating are used. Fuse specifications are contained in this
previous section, and the label on the unit’s front panel.
ESD CAUTION
Electrostatic Discharge (ESD) must be avoided so as not to damage or
destroy static sensitive components in the OSA 5240. Please observe
proper ESD handling procedures. Use an approved anti-static bracelet in
accordance with company practice.
WATER AND MOISTURE
Do not place containers with liquids such as coffee, water, sodas, etc. on
this unit. Do not operate this equipment in a wet environment.
HEATING
Do not install this product near heat sources such as radiators, air ducts,
areas subject to direct, intense sunlight, or other products that produce heat.

Introduction
OSA 5240 - User Manual - Revision P - June 2009
1-6
VENTILATION
Slots and openings in the chassis are provided for ventilation and to ensure
reliable operation of the product. To protect the unit from overheating, those
openings must not be blocked or covered. When integrating this unit in a
rack cabinet, at least one inch (2.5 cm) of clearance above and below the
unit is necessary to assure sufficient cooling.
GROUNDING
EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING TO THE
SUPPLY.
The OSA 5240 shelf must be connected to Earth Ground (common bounding
network (DC-C)). The wire used for the connection must be a minimum of
AWG16.
Ensure that all other devices connected to the 5240, are connected to
protective (earth ground). (Grounding one conductor of a two-conductor
outlet is not sufficient.)
Any interruption of the protective (grounding) conductor (inside the
equipment) or disconnecting the protective earth terminal is likely to make
this equipment dangerous. Intentional interruption is prohibited.
POWER
Make sure the power sources are compatible with the power inputs of the
equipment. Verify that the correct fuses are installed. The equipment's
protective earth terminals must be connected to the protective conductor of
the (mains) power cord or the station earth. The mains plug shall only be
inserted in a socket outlet provided with a protective earth contact. The
protective action must not be negated by the use of an extension cord
(power cable) without a protective conductor (grounding).
Make sure that only fuses with the required rated current and of the specified
type (normal blow, time delay, etc.) are used for replacement. The use of
repaired fuses and the short-circuiting of fuse holders must be avoided.
Whenever it is likely that the protection offered by fuses has been impaired,
the equipment must be made inoperative and be secured against any
unintended operation

POWER CORD PROTECTION
The power supply cord for this product should be routed or installed in such
a manner to protect it from being walked on or pinched. The unit should be
powered down completely before connecting or disconnecting the power
cable. The power cord should be removed before moving the unit. The
power cord must be placed near an easily accessible unobstructed socket
outlet.
CLEANING
Connected and running equipment can only be dusted using a soft dry cloth.
ONLY WITH, AUTHORIZED PERMISSION, OUT OF SERVICE &
UNPLUGGED equipment can be cleaned with a soft cloth slightly moistened
with a mild detergent solution. Do not use liquid cleaners, aerosols, abrasive
pads, scouring powders or solvents, such as benzine or alcohol. Ensure the
surface cleaned is fully dry before reconnecting power.
SERVICING AND MODIFICATIONS
To avoid dangerous electric shock, do not perform any servicing or
modifications other than what is recommended in this User Manual. Do not
attempt to gain access to areas of the unit where dangerous voltages are
present. Refer servicing to qualified service personnel.
DAMAGE REQUIRING SERVICE
•Refer servicing to qualified service personnel under the following
conditions:
•When the power supply cord is damaged.
•If liquid has been spilled into the enclosure of the unit.
•If the product does not function normally by following the instructions
in the User’s Manual. Adjust only those controls that are covered by
the operating instructions. Improper adjustment of other controls may
result in damage and will often require rework by a qualified
technician to restore the product to its normal operation.
•If the product has been damaged in any way.
When the unit displays a negative, distinct change in performance.

1.4 Warranty
This Oscilloquartz product carries a warranty which commences from date of dispatch
from factory. Unless agreed otherwise or stipulated differently on the original
acknowledgement of order, the duration of the warranty is twenty four months.
It applies to demonstrably faulty material or poor workmanship, but excludes batteries.

this not be possible for reasons beyond our control, all additional costs are at customer
expense.
Repairs under warranty carry either the balance of the original warranty or a six months
warranty, whichever is longer.
Damages resulting from natural wear, improper maintenance, failure to observe the
operating instructions, excessive strain, unsuited consumption material as well as
improper environmental and mounting conditions are excluded from this warranty.
The warranty expires if the customer or a third party modifies or repairs the product
without Oscilloquartz's prior written consent or if the customer does not take immediate
steps to prevent the damage from becoming more serious; likewise, if insufficient time is
provided for repair or replacement.
The customer will not be entitled to other warranty claims. Oscilloquartz is not liable for
consequential damage.
