Replacing the Batteries
The hand-held transmitter/receiver batteries have a service life of approximately one year. We recommend that
you use alkaline batteries. Rechargeable batteries are not permitted.
The procedures below explain how to replace the batteries. Be sure to follow the instructions carefully. If the
batteries are inserted incorrectly, the electronics or drive may be irreparably damaged.
Replace the batteries only after the appliance has been completely switched off.
To replace hand-held transmitter batteries:
1. Open the cover on the back of the transmitter.
2. Remove the batteries from the battery compartment.
3. Place three new 1.5V batteries (AAA type) in the battery compartment, as indicated.
4. Close the cover.
To replace receiver batteries:
1. If you have an access panel, open it and carefully pull the receiver out. Do NOT disconnect any
wires.
2. Open the cover.
3. Remove the batteries from the battery compartment.
4. Place four new 1.5V batteries (AA type) in the battery compartment, as indicated. The negative
end (-) of the battery must always be at the contact spring end of the compartment.
