Omron Comp Air Elite NE-C30-E [35/36] About the memory effect

11. Using optional accessories

When battery power is low

The charge indicator on the main unit will light

when battery power is low. Please note the

following points about using the device after the

charge indicator lights:

• Stop using the device when the charge indicator

comes on.

• Battery power is low and the device will cease to

operate shortly after the charge indicator comes

on.

• To continue using the device after the charge indicator comes on, use the AC

adapter or an alternative power source to power the device.

• Always fully charge the battery before using it again after the charge indicator

lights.

• If the operating time for each charge when using the battery become noticeably

shorter than usual, refer to “About the Memory Effect” below.

If the battery will not be used for a long time

• If the battery is not used for approximately 10 days after being charged, the

battery capacity will be reduced to about half that of normal due to self-discharge

of the battery power. If the battery will not be used for a long time, use the battery

until the charge indicator on the main unit lights (to fully discharge the battery)

before charging it.

About the Memory Effect

• If the battery is repeatedly charged before it has fully discharged, the operating

time possible for each charge will gradually be reduced. This is known as the

“memory effect” and is normal for nickel metal hydride (NiMH) batteries. It does

not indicate a battery error or malfunction.

• If the operating time for each charge become reduced, fully charge the battery

and operate the device until the unit stops operating (rather then when the charge

indicator lights) two or three times in a row. This should restore the battery

capacity to normal. If the battery capacity does still not return to normal, replace

the battery with a new one.
