POWERING THE MONITOR

UNPACKING THE MONITOR

TURNING THE MONITOR OFF

The CSM-BC400 is battery powered, with the ability to plug into AC power using 
the CSM-AC AC power adaptor/cord (sold separately) to minimize battery drain/
replacement.
Installation of four AA alkaline batteries is required, even when using the AC power 
connection. The batteries serve as a backup in the event of a power outage.
NOTE: Once batteries are installed, the monitor needs to be either syncronized to a 

wireless pad (and kept within approximately 30 feet of each other) or have 

a corded pad plugged into it within five minutes, otherwise a PAD/SIGNAL 

LOST notification will occur.

When you want to place the monitor out of use for any given period of time, remove 
all cords from the monitor and press the RESET button to cancel the alarm. The 
monitor will automatically be placed in a sleep mode
NOTE: The pad will remain programmed to the monitor unless it is either 

sychronized to another pad or the monitor has a corded pad plugged into it. 
Therefore, if placing the monitor out of service for extended periods, removal 
of the batteries is recommended. 

This optional setting prevents the monitor from alarming for 30 seconds when 
pressing the Reset button while, for example, the caregiver takes the patient 
out of bed.
1. Turn the PAUSE ON/OFF switch located in the battery compartment to ON to 

enable the monitor to operate the Pause feature.  

2. The patient/resident should be positioned on the pad or have the seat belt 

fastened

3. Press the RESET button to prevent it from alarming for 30 seconds. The LCD 

will read “STANDBY XX SEC.” indicating the number of seconds remaining 
in the pause mode. 

4. During the 30 second Pause Mode period, the patient/resident may be 

removed from the pad or the seat belt can be unfastened without activating 

an alarm. If the patient/resident  is placed back on the pad or the seat belt 

is fastened, the monitor will reactivate.
NOTE: If the sensor cord is removed during the pause mode, the monitor 

will alarm when the 30 seconds have expired (no cord removal 

alarm will occur with the floor mat/pad).

5. When the 30 seconds have expired:

• If the patient/resident has not been placed back on the pad/seat belt 

refastened, the monitor will go into a sleep mode.

• If the patient/resident has been placed back on the pad/seat belt 

refastened, the monitor system will reactivate.

NOTE: When the PAUSE switch is in the OFF position, the RESET button will 

only serve to cancel the alarm.

This  optional  setting  allows  the  caregiver  to  place  the  monitor  in  a  tamper 
resistant mode by turning the switch on left side of monitor from KEY OFF to KEY 
ON. When in the KEY ON mode:
• The Reset/Pause, Volume, Delay, and Tone controls on the monitor will not 

function unless first overridden by the CareSense Key. This is accomplished 
by positioning the KEY icon on CareSense Key over the matching KEY icon 
on the top right face of the monitor (see illustration below) and holding it 
over the icon until one of the control buttons is pressed.

• If the alarm has been activated, the alarm may be canceled as soon as the 

CareSense Key is positioned over the KEY icon on the monitor (there’s no 
need to press RESET button to cancel the alarm).

NOTE: When the switch is in the KEY OFF position, the Reset/Pause, Volume, 

Delay, and Tone controls on the monitor are fully operational (no 
caregiver key is required to override).

When connected to the monitor, a Nurse Call Cord allows the patient/resident to 
activate the monitor alarm and, if Nurse Call is connected, place a call to the 
Nurse’s Station (works with “normally open” nurse call systems only).
• 1⁄4" call cord plug is inserted into the monitor receptacle labeled “CALL CORD”
• The monitor alarms only when the call cord button is depressed (the LCD 

will read “NURSCALL ALARM”)– when the button is released, the monitor 
alarm will cease. Nurse Call, if connected, will remain on until it is reset at 
the patient station. 

• If the Call Cord is removed from the monitor, the monitor will alarm, and a 

call will be placed to the Nurse’s Station (if connected). The LCD will read 
“CALLCORD LOST”. The alarm may be cancelled by pressing the RESET 
button or reinserting the Call Cord jack into the monitor. Nurse call, if 
connected, will remain on until reset.

The CareSense Wireless Advanced LCD Bed and Chair Monitor System is 

intended  for  use  only  by  trained  healthcare  professionals  at  healthcare 

facilities and not for consumer or residential use.

NEVER use this monitor in place of visual monitoring by a caregiver.
This  monitor  cannot  prevent  falls.  The  caregiver  must  make  frequent 

visual inspections of the patient/resident to ensure the monitor is properly 

placed.  Visual  inspections  by  the  caregiver  are  essential  to  reduce  the 

risk of falls.

Although  the  CareSense  Wireless  Advanced  LCD  Monitor  is  able  to 

communicate up to 30 feet away from the patient/resident, it is recommended 

that the monitor be placed in close proximity to the patient/resident.
Communication  distance  varies  for  each  facility.  Test  at  the  desired 

distance prior to putting the system into service.
