RX-I and RX-II models have two buttons. The Power/Set button is located on top of the rangefinder, and the Mode button is located on the left side of the rangefinder.
RX-III and RX-IV models have three buttons, all located on the top of the rangefinder. The Power button is closest to the user’s eye and is the largest. The Mode button is located in the middle of the three buttons. The Set button is farthest from the user’s eye.
The Power button is used to activate the rangefinder, as well as actuate the laser (obtain a return). All Leupold rangefinders shut off after a brief period, saving battery life and menu changes that may have been made.
The Mode button is used to enter and to navigate through the Quick Set Rotary Menu. Pressing the button initially enters the menu, each subsequent depression advances to the next available icon.
The Set button is used to turn the highlighted icon (in the Quick Set Rotary Menu) on or off. Each time the Set button is pressed, the selected icon toggles from off to on or vice versa. If the Set button is held depressed prior to entering the Quick Set Rotary Menu, the backlight (RX-III and RX-IV only) will illuminate until the button is released.
Activating a mode.
The Mode button is used to enter, and advance through, the Quick Set Rotary Menu. The Set button is used to toggle each menu option on/off. To activate a mode, press the Mode button until the appropriate icon is flashing, then press the Set button. If the icon is displayed steadily, the mode is turned on.”
Deactivating a mode The Mode button is used to enter, and advance through, the Quick Set Rotary Menu. The Set button is used to toggle each menu option on/off. To turn a mode off press the Mode button until the appropriate icon is flashing, press the Set button until the icon is displayed steadily, then press the Set button again until the icon resumes flashing. It is important to note that as the user navigates through the Quick Set Rotary Menu, each icon will flash to show their current position in the menu. This initial flashing of the icon is only intended to show currently location in the menu and does not indicate the status of that mode (on or off). To make sure a mode is turned off, it should be turned on, then off; this will require pressing Mode until the icon is flashing (showing the user’s current location in the menu), pressing Set to turn the mode on (the icon will display steadily), then pressing Set again to turn the mode off (the icon will begin flashing again). This can be a bit confusing as the icon will flash initially to show the user’s location in the rotary menu, then it will display steadily to show the mode has been activated, then will flash again to indicate the mode has been deactivated. Flashing serves a dual-purpose, it initially acts as a place holder in the menu, then it acts to indicate a deactivated (turned off) mode.
