Honeywell DCP552 Mark II - Manual (Page 179)

10-8
10 - 3 When the BAT LED Flashes
Handling Precautions
Batteries that have been stored for long periods have been subject to self-
discharge and have a short service life. If required, buy new batteries.
■ BAT LED flashes
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 DCP552 has been stored for long
periods disconnected from the power line.
■ Replacing the battery
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 DCP552 causes the data stored in RAM to be lost.
● Items to be provided by the user
• Phillips screwdriver
• New lithium battery: model number 81446140-001
Chapter 10. TROUBLESHOOTING
CAUTION
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.
Do not throw used batteries into a fire or discard them as general garbage,
but return them to Honeywell sales/service office or the dealer from whom
you purchased the equipment.
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.
