HANDLING PRECAUTIONS

BAT LED flashes

Replacing the battery

Be sure to turn off the power supply when you are replacing the batteries.
Failure to heed this warning may lead to electric shock.
Be sure not to touch internal components during battery replacement or
just after the power has been turned. This may result in burn injuries.
• Make sure that the batteries are inserted with the plus (+) and minus (–) poles correctly oriented.
• Do not use damaged batteries or batteries that leak.
• Do not throw batteries into a fire, recharge, disassemble or expose them to heat.
• Store batteries in a cool, dry place.
Failure to heed these cautions may result in burns or battery leakage.
Batteries should be kept out of reach of children, since they may swallow
them. Should a child swallow a battery, contact a doctor immediately.
When disposing of used batteries at the user site, observe local bylaws.
Before you touch internal components, be sure to discharge any static
electricity on your body by touching a metal ground connector. Failure to
heed this caution may lead to equipment damage.
Items to be provided by the user
10-8
Batteries that have been stored for long periods have been subject to self-dis-
charge and have a short service life. If required, buy new batteries.
The BAT LED starts flashing when low battery voltage is detected. The voltage level set
in memory that trigger the LED is higher than minimum level required for storing data.
Thus data loss is thus not imminent when the LED starts flashing.
Note, however, that memory data corruption has probably occurred when the BAT LED
starts flashing at power up after the DCP551 has been stored for long periods discon-
nected from the power line.
Parameter settings and program settings are stored in RAM memory. The RAM is
backed up by a battery and data persist through a power down. When the battery is
depleted, turning off the DCP551 causes the data stored in RAM to be lost.
