IMPORTANT : Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power
to the unit.
WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (Where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly
other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHAT
SO EVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling
food.
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.
LITHIUM BATTERY HANDLING
This product uses a lithium battery for memory back-up.
WARNING : Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following pre-
cautions when handling or replacing lithium batteries.
Leave lithium battery replacement to qualified service personnel.
Always replace with batteries of the same type.
When installing on the PC board by soldering, solder using the connection terminals provided on the battery cells.
Never solder directly to the cells. Perform the soldering as quickly as possible.
Never reverse the battery polarities when installing.
Do not short the batteries.
Do not attempt to recharge these batteries.
Do not disasemble the batteries.
Never heat batteries or throw them into fire.
ADVARSEL!
Lithiumbatteri-Eksplosionsfare ved fejlagtig handtering. Udskiftning ma kun ske med batteri af samme fabrikat og type. lever det brugte
batteri tilbage til leverandren.
VARNING
Explosionsfara vid felaktigt batteribyte.
Anvand samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.
Kassera anvant batteri enligt fabrikantens instruktion.
VAROITUS
Paristo voi rajahtaa, jos se on virheellisesti asennettu.
