5. Select Wake Up Lithium Ion Battery in SLOT A. Then, the 
patient monitor applies a “wake-up” shot of current for up to 210 
seconds. 
6. Watch for the message, Battery awake, run main code to charge. 
The battery should now be “awake.” 
 If the “Battery awake, run main code to charge” message 
appears but the battery is NOT awake, the battery may be in a 
deep discharge state. You should repeat step 5 at least four more 
times to give the battery additional “wake-up” shots of current.
7. Quickly reboot (or power cycle) the patient monitor to begin charging 
the batteries. The patient monitor’s illuminated yellow-colored 
CHARGING STATUS LED indicates that the battery is being 
charged.
NOTE
The patient monitor will not charge the battery while it is 
running the Boot Loader program.
