2. CHECK BATTERY CAPACITY
HINT:
Make sure to use the TOYOTA electrical tester.
With the battery unloaded, judge can not be made wheth-
er the battery is available or not on the test.
When the transmitter is faulty, the energy amount left in
the battery might not be checked correctly.
On the lithium battery used for the transmitter, the voltage
more than 2.5 V with the battery unloaded is shown on the
tester until the energy is completely consumed.
Accordingly when inspecting the energy amount left in the
battery, it is necessary to measure the voltage when the
battery is loaded (1.2 kW).
(a) Remove the cover using a (±) driver.
(b) Remove the battery (lithium battery) from the transmitter.
(c) Connect the lead to the (±) terminal of the transmitter and
install the battery.
(d) Connect the (+) tester to the (+) battery (lithium battery),
and (±) tester to the lead respectively.
(e) Press one of the transmitting switches on the transmitter
for approx. 1 second.
(f) Press the transmitting switch on the transmitter again to
check the voltage.
Standard: 2.1 V or more
