Translations:KAVAN Beta 1400 - Instruction manual/51/en

Remove the battery compartment hatch on the back side of the transmitter, pushing the cover at the arrow mark with your thumb. Load 4 fresh alkaline batteries or AA-size accumulators, carefully keeping the correct polarity (marked on the bottom of the battery holder). Plug the battery holder cable into the socket at the bottom of the battery compartment, keeping the correct polarity (+) red wire, (-) black wire. (The transmitter features a protection circuitry – if you connect the plug the other way around, the transmitter will not work but will not get damaged by reversed polarity.)
