Using
Power & Display Switch
The power switch and display switch of the T4PKSR are integrated. In the PWR ON
mode, radio waves are transmitted and in the DISP ON mode, model data, settings can
be checked without transmitting radio waves.
Power Off Forgotten Alarm
When the steering wheel, throttle trigger, push switch, or edit button are not operated
for 10 minutes default, an alarm sounds and "NOT OPERATED FOR A LONG TIME"
is displayed on the LCD screen.
When the steering wheel, throttle trigger, push switch, or
edit button are operated, the alarm is reset. If the system is
not to be used, turn off the power.
The function can be deactivated at the system menu (p.122).
High Voltage Alarm
If a battery exceeding 8V is used with the T4PKSR, an au-
dible alarm will sound and "HIGH VOLTAGE" will be dis-
played on the LCD screen.
Immediately remove the battery because it may cause damage
to the T4PKSR.
Low Battery Alarm
If the transmitter battery voltage drops to 5.0V(when using dry cell battery: 4.2V) or
less, an audible alarm will sound and "LOW BATTERY" will be displayed on the LCD
screen.
Since Ni-MH and LiFe batteries have a different usable range than dry cell batteries, the
power source used must be selected at system setting (p.122).
 Warning
￸ When a low battery alarm is generated, cease operation imme-
diately and retrieve the model.
If the battery goes dead while in operation, you will lose control of the model.
