WM—220
The WM-220 employs the cross-over battery check system which permits easy-to-see
monitoring of the battery status with 2 LEDs (green and red). The brightness of the
both LEDs changes as shown below.

It is possible to use unit continuously for another 5 hours after the red LED comes
on. When it lights more brightly than the green LED does, it signals the time that the
battery needs replacement (only 2 hours is available for use until the battery
capacity is exhausted).
The battery voltage is not stabilized for first several minutes after the power switch
is turned on. So, perform the checking of the LED lighting several minutes after power
is switched on. Also, if the red LED is illuminated more brightly than the green LED
when the power switch is turned off, you should replace the battery with the new one.
The transmitter is made to give up to 30 hours of continuous operation from an
alkaline battery.
