In a canon sure shot 105 what does a blinking H mean?

In a Canon Sure Shot 105, a blinking "H" indicates that the camera is in a high-speed mode, often related to low light conditions or when using the flash. This warning informs the user that the camera may be adjusting its settings to ensure proper exposure. If the "H" continues to blink, it may suggest that the camera is unable to achieve the desired settings, so it's advisable to either adjust the lighting conditions or check the battery status.
