1. GENERAL DESCRIPTION OF THE RF TRANSMITTER
The Mazda J61/J64 RKE transmitter is a handheld device to remotely control
a vehicle's locking and alarm system by pressing the pushbuttons.
Delivered by Siemens is only the transmitter part with the pushbutton
electronics. It is intended to be put together with the flip-fork (right side of the
picture) which is delivered to Mazda by the lockset supplier. It provides
mechanical access to the vehicle and start of the car using a separate,
discrete transponder.
The picture shows the four-button variant of the transmitter.
There are variants of the transmitter with two, three, or four buttons, listed in
the following table.

power supply of +3V.
3. TYPICAL USAGE PATTERN (FOR EUROPE ONLY)
20 lock/unlock operations in 24 hours with complete transmission duration
of
2.0 seconds (100ms/operation)
4 lock/unlock operations in 24 hours with transmission duration
of 26 seconds ( 6.5 seconds for 1 operation; max. value)
→ total transmission duration of 28 seconds within 24 hours
Transmitter ON 1.2 seconds / hour
Transmitter OFF 3598.8 seconds / hour
Duty Cycle: TON / T (ON+OFF) x 100% = 1.2/ 3600 x 100 % = 0.033 %
