INSPECT DOOR LOCK TRANSMITTER OPERATION

Inspect operation of the transmitter.

Remove the battery (lithium battery) from the trans-

mitter (see page

Install a new or normal battery (lithium battery).

When a new or normal battery is not available, connect 2 new

1.5 V batteries in series, connect the battery's positive (+) to the

battery receptacle side terminal and battery's negative (-) to the

bottom terminal, then apply 3 V of voltage to the transmitter.

In a location that is approx. 1 m (3.28 ft) away from

the driver side outside door handle in the right direc-

tion, point the key plate of the transmitter at the ve-

hicle and check operation of the transmitter by

pressing the transmission switch on the transmitter

The door lock can be operated via the remote control.

The minimum operational distance differs depending on

the operator, the way the transmitter is held and the loca-

Since the transmitter uses faint electric waves, the opera-

tional distance might be shortened if noise or strong elec-

tric wave occurs in the area where the frequency is used.

Install the battery (lithium battery).

Inspect the battery capacity.

The capacity of the battery can be determined only when

the battery is installed in the transmitter. For a lithium bat-

tery used in the transmitter, a voltage of more than 2.5 V

is shown on the tester until the energy is completely con-

sumed, while no battery is installed in the transmitter.

Therefore, it is necessary to measure the voltage while

the battery is installed in the transmitter (a resistance of

1.2 kΩ is applied to the battery) when checking the

amount of energy left in the battery.

If the transmitter is faulty, the amount of energy left in the

battery might not be checked correctly.

Remove the battery (lithium battery) from the trans-

mitter (see page
