Battery Replacement
Transmitters include a replaceable 27A, NM27-sized, 12 Volt, alkaline battery.
The battery should be replaced when a button press does not result in either a
flash of the LED, reliable read range, and/or the shutter/gate does not operate.
To replace the battery, follow the directions below:
Using a Phillips screwdriver; remove the small screw in the back of the Trans-
mitter.
Unsnap the back of the case.
Remove the old battery. Insert the new 27A,
NM27-sized, 12 Volt, alkaline battery. Be sure
the plus (+) side of the battery is orientated
towards the Transmitter’s LED and away from
the key ring holder.
Replace the back of the case, snapping it back into place. Reinstall the screw.
The 27A, NM27-sized, 12 Volt, alkaline battery was specifically selected for use
with the Ranger Transmitter. When replacing, only use this type of battery. It
supports a relatively high current drain when used on an intermittent basis,
such as when a button is pressed. This alkaline battery is widely available, and
commonly used in electronic devices, including cameras.
Dispose of the battery according to local requirements. Recycle when possible.
For best performance, it is important that the Transmitter be used as far from
interference sources as possible. These sources may include, but are not lim-
ited to, large metal obstructions, such as duct work and appliances, as well as
magnetic fields and radio emissions.
