Transmitter Battery: Inspection

INSPECT BATTERY CAPACITY
HINT:
- When checking the amount of energy left in the battery (lithium battery), the battery must be checked while it is installed in the transmitter (1.2 kW is applied to the battery). When the battery is checked while it is uninstalled, the voltage reading will be more than 2.5 V until the energy is depleted.
- If the transmitter is malfunctioning, the voltage reading of the energy left in the battery may be inaccurate.
1. Connect a wire to the negative (-) terminal of the transmitter and install the battery.

2. Connect the tester's positive (+) lead to the positive (+) side of the battery (lithium battery) and the negative (-) lead to the wire.
3. Press one of the transmitter switches for approximately 1 second.
4. Press the transmitter switch again to check the voltage.

  Standard voltage:
  
  2.2 V or higher
  
  HINT:
  - When the temperature of the battery is low, the inspection results may be inaccurate. When the outcome of the test is less than 2.2 V, conduct the test again after leaving the battery in a place where the temperature is 18°C (64°F) for more than 30 minutes.
  - Read the voltage immediately after the switch is pressed. 0.8 seconds after the switch has been pressed, the automatic power-off function starts and resistance applied to the battery will cease. The voltage of the battery will be 2.5 V or more.
  - Press the switch at least 3 times before reading the voltage. If the battery has just been returned to 18°C (64°F), the voltage may be unusually high for the first or second voltage reading.
5. Disconnect the lead.
