Channel
The channel of a transmitter can be programmed into one or more receivers.
One receiver is operated through an individual command, several receivers
through a group command.
Channel indicator lamp
A radio signal is indicated by the channel indicator lamp lighting up. When the
battery starts to lose power, the channel indicator lamp flashes when transmit-
ting. The transmission strength and the radio range decrease as battery power
declines. If the channel indicator lamp no longer lights up when a button is
pressed, the battery must be replaced.

When used properly, the rib on the handle of the tool serves as an orientation
aid for setting the threshold value.
