Power & Display Switch
The power switch and display switch are push switches.
When the power switch (PWR) is held down, operation starts by transmitting radio waves. When
the display switch is held down, the transmitter side data can be checked and set. When the power
is turned off, if the power switch or display switch is held down, the power is turned off. If both
switches are pressed simultaneously, the power is turned off quickly.
Power Off Forgotten Alarm & Auto Power Off
At T4PX initialization, if steering wheel, throttle trigger, push switch, edit button, or other
operation is not performed within 10 minutes, an audible alarm will sound and the message
"Warning: Auto power off" will appear.
If steering wheel, throttle trigger, push switch, edit button or other
operation is performed, the alarm is reset. Also turn off the power
when the transmitter is not in use. If the alarm is not reset, the auto
power off function will automatically turn off the power after 5
minutes. If you do not want to use this alarm and the auto power off
function, they can be disabled by system setting (p.148).
Low Battery Alarm
If the transmitter battery voltage drops below the usable range, an audible alarm will sound
and "Low battery" will be displayed. Since the usable range of LiFe and NiMH batteries and
LiFe batteries is different, the power supply used must be set by system setting. If the battery
goes dead while running (cruising), since there is the danger of collision, immediately recover
the vehicle (boat) and stop running (cruising).
Warning
When a low battery alarm is generated, cease operation immedi-
ately and retrieve the model.
If the battery goes dead while in operation, you will lose control of the model.
