When the transmitter is switched ON, the
battery power LED (red) will blink once to
denote the batteries installed are in good
condition.
If the LED remains illuminated the batteries
have expired and require replacement.
This transmitter requires two
AA batteries to operate.
To install, open the battery cover
and insert the batteries into the
battery compartment.
Note: Batteries contain a corrosive acid that may leak and damage the transmitter when stored for a long
period. Batteries should be removed from the transmitter before storing without use for more than 4 weeks.
