Battery installation & indicator
This transmitter requires 2 x AA batteries to operate.
To install, remove the battery cover and slide the batteries into the battery compartment &
replace the battery cover.
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.
When the transmitter is switched ON, a red LED  will blink once to indicate the batteries
installed are in good condition. If the LED remains illuminated, it means the batteries are
weak and require replacement.
