-5 is set to 4.5v. When the main battery 12 is used and the voltage gradually decreases to 4.5V or less, the detection I
Cl3 turns ON, and O via AND gate 1-21.
A signal is applied from the R games 1 to 23 to the LED unit 1 6, and the LED unit 6 emits green light to warn that the remaining battery power is getting low. If you continue to use the handy terminal 1 in this state without replacing or charging the battery, the battery voltage will further drop and when it becomes 4.3V or less, the detection IC 14 will turn on and, via the AND gate 20, Through the OR gates 22 and 23, the green and red lights of the LED unit 6 are emitted and recognized as orange, giving a warning that the remaining battery power is getting even lower. Furthermore, when the handy terminal 1 is used, the battery voltage further decreases to 4°0V or less, the detection ICl 3 is turned on, and the OR gate 22 is turned on via the A N D gate 19.
A signal is applied to LED unit 6 from LED unit 1.
-6 red light will be emitted to warn you that the battery is almost empty.
