Waking up the battery with a Cadex SMart Two+ charger
NOTE
A deep discharged battery will require you to repeat the following 
steps more than once before the battery will “wake up.”
1. Insert the battery into the battery charger and wait for the RUN 
LED light to illuminate (approximately three minutes). 
2. If the RUN LED light does NOT illuminate, complete the following 
steps:
a. Remove the battery from the battery charger.
b. Re-insert the battery into the battery charger and let the battery 
trickle charge for two to three minutes while the FAIL LED 
flashes. (If the RUN LED light lights, ignore it.)
c. Watch the battery charger LEDs and immediately remove the 
battery from the battery charger when the FAIL LED stops 
flashing and remains illuminated, or when both the RUN and 
CONDITION LEDs flash.
d. Wait for one to two seconds, then re-insert the battery into the 
battery charger. The RUN and CONDITION LEDs will flash for 
five to ten seconds while the charger initializes the battery. If the 
FAIL LED lights, remove the battery and re-insert it into the 
battery charger.
e. Watch the battery charger LEDs. The RUN LED should stop 
flashing and remain illuminated for approximately one minute 
later the CONDITION LED should stop flashing. At this time, 
the battery is awake and being charged.
Waking up the battery with a patient monitor
NOTE
Non-recommended (incompatible) batteries will not wake up the 
Dash patient monitor.

ZERO ALL (FUNCTION).

c. Keep holding NBP Go/Stop (or NBP Auto) and ZERO ALL 
(FUNCTION) until the Boot Code information appears on the 
display.
3. Select Wake Up Battery from the Service Menu.
4. Insert the “sleeping” battery into slot A of the patient monitor.
NOTE
In some languages, slot A is identified as slot 1 and slot B is 
identified as slot 2.
