If LED goes off approx. 2 sec. after finger is removed from button, batteries need replacement.
No LED, and shutter locks. Check battery installation or change batteries.
During shooting, replace batteries when:
a)Film-advance speed, operation speed of autofocus lens or flash recycling time is noticeably slower, or
b)Lightly pressing the shutter release button causes the self-timer indicator LED to start blinking and the shut- ter to lock.
At low temperatures or when weakened batteries are used, film advance may cause low battery voltage for a moment and the self-timer indicator LED may blink for a short while. However, you may be able to continue shooting.
The microcomputer in the F-401x may turn the camera off, even when batteries with sufficient power are prop- erly installed. To start or resume operation, remove batteries and install again.
