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: THIS APPARATUS MUST BE EARTHED
IMPORTANT
THE WIRES IN THIS MAINS LEAD ARE COLOURED IN
ACCORDANCE WITH THE FOLLOWING CODE:
GREEN-AND-YELLOW : EARTH
BLUE : NEUTRAL
BROWN : LIVE
As the colours of the wires in the mains lead of this apparatus may
not correspond with the coloured markings identifying the terminals in
your plug, proceed as follows:
The wire which is coloured GREEN and YELLOW must be
connected to the terminal in the plug which is marked by the letter E
or by the safety earth symbol or coloured GREEN and YELLOW.
The wire which is coloured BLUE must be connected to the terminal
which is marked with the letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the
terminal which is marked with the letter L or coloured RED.

WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.
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-
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.
