Managing the Default Power Save Mode

The FT-991A’s default power save mode is designed to automatically enter sleep mode after a period of inactivity. This can be useful for conserving battery power, but it can also be inconvenient if you want to keep the radio on and ready to use. Fortunately, there are several ways to manage the default power save mode, allowing you to customize it to meet your needs.

2. Use the arrow keys to navigate to the “Power Save” tab.
3. Use the arrow keys to highlight the “Default” setting.
4. Press the [OFF] button.

Adjusting the Default Power Save Timer

If you want to keep the default power save mode enabled, but you want to adjust the amount of time before the radio enters sleep mode, you can do so by following these steps:

1. Press the [MENU] button.
2. Use the arrow keys to navigate to the “Power Save” tab.
3. Use the arrow keys to highlight the “Timer” setting.
4. Use the arrow keys to adjust the timer to the desired amount of time.

Using the Power Save Button

You can also use the power save button to manually enter or exit sleep mode. To do this, simply press the [POWER SAVE] button. When the power save mode is active, the power save icon will be displayed on the LCD screen.

Customizing the Default Power Save Settings

In addition to the basic power save settings described above, you can also customize the default power save settings by accessing the power save menu. To do this, follow these steps:

1. Press the [MENU] button.
2. Use the arrow keys to navigate to the “Power Save” tab.
3. Use the arrow keys to highlight the “Custom” setting.

Tips for Managing the Default Power Save Mode

Here are a few tips for managing the default power save mode on your FT-991A:

* If you are using the radio in a portable application, you may want to disable the default power save mode to ensure that the radio is always ready to use.
* If you are using the radio in a fixed location, you can enable the default power save mode to conserve battery power.
* You can customize the power save mode to meet your specific needs.
* You can use the power save button to manually enter or exit sleep mode.

Resetting the Default IF Gain

Adjusting the IF gain level can optimize the receiver’s sensitivity and dynamic range. However, if the setting is altered inadvertently or you wish to restore the factory default, follow these steps:

Enter the “MENU” mode by pressing and holding the “MENU” button on the front panel.
Use the arrow keys to navigate to the “IF AGC” menu.
Press the “SET” button to enter the IF AGC menu.
Locate the “IF Gain” setting.
Press and hold the “SET” button until the IF Gain value starts flashing.
Use the arrow keys to adjust the IF Gain to the desired value.
Press “SET” again to confirm the change and exit the menu.

Additional Information:

The IF Gain setting is typically set between 0 and 10. Higher values increase the receiver’s sensitivity, making it more responsive to weak signals. However, excessively high IF Gain can also amplify noise and reduce the receiver’s dynamic range.

For optimal performance, it’s recommended to adjust the IF Gain while monitoring the on-screen signal strength indicator. Gradually increase the IF Gain until the signal strength reaches a peak without introducing noticeable noise.

Recommended IF Gain Settings:

The following table provides recommended IF Gain settings for different signal conditions:

Signal Strength	Recommended IF Gain
Strong Signals	0-2
Medium Signals	3-5
Weak Signals	6-8

It’s important to note that these settings are only general recommendations and may need to be adjusted based on specific operating conditions and individual preferences.
