7.4.4 Memory Backup
After recording has been completed, protects the contents of the recorded image when the power
switch has been turned off or the power cord has been disconnected. When power is turned on, it
returns to the identical state immediately after recording.
1) Battery
Type Nickel cadmium: 3x4
Nominal Capacity 600 mAh
Nominal Voltage 4.8V
Life 1 year
The batteries are not rechargeable. The life of the batteries may vary dramatically depending on
the ambient temperature and conditions of use. It is possible to use batteries past their shelf life
but there is a possibility they may not meet specifications and so should be replaced annually.
2) Backup Time 2 hour
3) Backup Start Conditions
After recording has been completed, if the DC input voltage to the MEMRECAM main unit is
19.0V or less.
4) Charging
Time Approximately 10 hours(from completely dead battery to full charge)
Start Conditions With an external power source for the DC input connector of this unit.
Note ) Since it is designed to reduce deterioration due an overcharged battery, it is possible to
extend the life of the battery by avoiding continuous charging for three days or more.
5) Battery Status Display
The battery status is shown by the color of the MB LED on the rear panel of the camera.
5.1) Color Shown
Color Shown Charge Remaining
Red Low
Orange Medium
Green High
Since there are differences in batteries and the ambient temperature, the display is not precise.
Use as directed. If the color of the flashing LED changes from orange to red while backing up,
charge as soon as possible (connect the external power source to the DC input connector of the
camera). Otherwise, the excessive discharge protective function is activated and the images in
the memory are lost.

If valid image data is not saved in the memory, the backup does not start.
5.3) Replacing Batteries
With normal use (charge and discharge several times per day at normal temperatures), the life
is about one year but the life can vary depending on storage temperatures, the number of
charges and the time of continuous charging.
During actual use, the time for the color of the flashing LED to turn red may be shortened in
spite of an adequate charge, which may impact the use.
Avoid using or storing in locations of high temperatures will extend the life of the battery.
Using nickel cadmium batteries improves the efficiency of the memory when the battery is
completely discharged, and thus extends the life of the battery.
Remove the cover of the main unit of the camera to replace the battery.
