Note in the picture below that the battery charge indicator in the upper right hand corner is showing a depleted battery.
If this condition exists on either phone at the start of a launch day, you will be delayed from winch launching until the battery is brought back up to charge enough to operate the phone.
Remember, the Winch phone only receives a trickle charge when the master switch is turned on.
If the phone had been left on overnight, you will most likely have a completely dead battery and the phone will have a blank display. Holding the red on/off button will have no effect.
This is why it is so important to make sure that both phones are turned off at the end of the day.
