Precaution Statements 

Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as 
electrical shock. 

1-1 Safety 

Precautions 

1.

Be sure that all built-in protective devices are 
replaced. Restore any missing protective shields. 

2.

When reinstalling the chassis and its assemblies, be 
sure to restore all protective devices, including 
nonmetallic control knobs and compartment 
covers. 

3.

Make sure there are no cabinet openings through 
which people - particularly children - might insert 
fingers and contact dangerous voltages.               
Such openings include excessively wide cabinet 
ventilation slots and improperly fitted covers and 
drawers. 

4.

Design Alteration Warning: 
Never alter or add to the mechanical or electrical 
design of the SECR. Unauthorized alterations 
might create a safety hazard.  Also, any design 
changes or additions will void the manufacturer’s 
warranty. 

5.

Components, parts and wiring that appear to have 
overheated or that are otherwise damaged should 
be replaced with parts that meet the original 
specifications.  Always determine the cause of 
damage or over- heating, and correct any potential 
hazards.                     

6.  Observe the original lead dress, especially near the 

following areas: sharp edges, and especially the 
AC and high voltage supplies.  Always inspect for 
pinched, out-of-place, or frayed wiring. Do not 
change the spacing between components and the 
printed circuit board.  Check the AC power cord 
for damage.  Make sure that leads and components 
do not touch thermally hot parts. 

7.  Product Safety Notice: 

Some electrical and mechanical parts have special 
safety-related characteristics that might not be 
obvious from visual inspection.  These safety 
features and the protection they give might be lost 
if the replacement component differs from the 
original - even if the replacement is rated for 
higher voltage, wattage, etc. 

Components that are critical for safety are 
indicated in the circuit diagram by shading,  (

)

or (

).   Use replacement components that have 

the same ratings, especially for flame resistance 
and dielectric strength specifications.  A 
replacement part that does not have the same 
safety characteristics as the original might create 
shock, fire or other hazards.

CAUTION

There is the danger of explosion if battery is incorrectly 
replaced. 

Replace only with the same or equivalent type 
recommended by the manufacturer.  

Dispose used batteries according to the manufacturer’s 
instructions.  

ATTENTION

ll y a danger d’explosion s’il y a remplacement incorrect 
de la batterie. 

Remplacer uniquement avec une batterie du même type 
ou d’un type équivalent recommandé par le constructeur. 

Mettre au rebut les batteries usagées conformément aux 
instructions du fabricant.
