External Battery Pack,  YRB02Z
 
 
can be recharged using the AC adapter 
(time it takes to Charge a completely dis-
charged battery pack: 15 hrs); see "Specifi-
cations" regarding hours of Operation. 
 
The balance automatically "recognizes" that 
it is being powered by a battery pack. 
When utilizing the battery pack, use the 
ON/OFF key 
(16)
 to turn the balance on and 
off (if the code 8 6 4 is set in the balance 
operating menu, you cannot turn the bal-
ance off using the ON/OFF key). 
After you turn off the balance, there is no 
supply of power for "Standby" Operation. 
The balance can also tell when it is being 
powered by line current, provided the AC 
adapter is plugged in and the line current 
supply is intact. If you utilize the battery 
pack, the code for automatic shutoff - 8 7 1 
should be set to increase the time you can 
operate the balance before having to re-
charge the batteries (see page 24 in addi-
tion).
