[. . . ] Both Channel's current Delay values are stored with each press of the STORE button. Each press of this button alternately recalls stored Memories (A then B then A. . . ) for the selected Channel only. A quick way to recall Memories into both Channels simultaneously, is to store both Channel's values into the same Memory. With both Channels selected (both CHAN LEDs on), press RECALL to restore both Channel's Memories at the same time. [. . . ] The MEMORY LED flashes when the current Delay value for the selected Channel is different than the stored value for the selected Channel. RECALL button: Pressing this pushbutton alternately Recalls stored Memories A and B, for the Channels(s) indicated by the green CHAN LEDs. CHANNEL LEDs: indicate the Channel number whose value is currently being displayed in the LED display and whose current Delay value is editable by illuminating green. If both CHAN LEDs are on, both Channel's current Delay values are editable. In this edit BOTH mode, the LED display shows the smaller of the two current Delay values and the memory LEDs turn off if the two Channel's current Memories are not the same. CHANNEL button: Pressing this button advances the Channel LEDs from CHAN 1 to CHAN 2 to BOTH. The current Delay value of the selected Channel is displayed in the LED display. (This button does nothing in Mono Mode. ) DISPLAY MODE button & LEDs: This button changes the units of displayed Delay values from Milliseconds to Feet to Meters. The LEDs indicate the current Display Mode: MILLISECONDS, FEET or METERS. 5 digit LED display: indicates the current Delay value for the selected Channel. When both Channels are selected, the smaller of the two Channel's current Delay values is displayed. This display also shows the current temperature setting when holding down the DISPLAY MODE button and pressing one of the up/down buttons. On power-up the current software revision level and internal Stereo/Mono (2CHAN/1CHAN) configuration are displayed. UP/DOWN buttons: Pressing these buttons increases/decreases the amount of Delay in the selected Channel(s). The two buttons just to the right of the LED display change Delay time in 1 millisecond steps. For distance displays (feet and meters), these buttons are FINE and COARSE adjustments, since Delay increments are always in 1 msec and 10 µsec steps, regardless of the DISPLAY MODE. TEMPERATURE setting: Holding down DISPLAY MODE while pressing the up/down buttons displays the current temperature setting in degrees Celsius for the 1 msec/COARSE buttons and degrees Fahrenheit for the 10 µsec/FINE buttons. No matter which unit (°C or °F), adjustments are always in 1°C steps (or 1. 8°F). Manual-2 REAR PANEL DESCRIPTION REMOTE RECALL terminals. Wiring external configuration switches to these terminals allows remote recall of the two nonvolatile memories for each Channel. These terminals use CMOS (+5 volt) logic levels and sink only 3mA (max. ) each. In this mode all front panel controls, with the exception of the CHAN and DISPLAY MODE buttons, are disabled. The Channel button remains active so the user may view the current Delay values without risk of changing them, and the display mode button allows display of Delay values in milliseconds, feet or meters. [. . . ] Press the CHAN button until the other CHAN LED is lit and edit its current Delay value. Both Channels simultaneously: If you've selected both Channels (both CHAN LEDs ON), the LED display shows the smaller of the two Channels current Delay values. Changing this value changes the other Channel's value by the same relative amount. Check the other Channel's current Delay value by selecting it with the CHAN button. [. . . ]
