after receiver is powered off. This facilitates easy setup by enabling quick selection of stored channels for any group, i.e, selecting any group will automatically display the last channel selected for that group. See section “11. U-800 Frequency Lists” for available channels in each group. The previous group and channel used is stored in memory automatically when receiver and transmitter are turned off after operation. Selecting a different group on the receiver in subsequent use will display a differ- ent channel as previously selected for that group, however, the transmitter will need again to be sync’ed to that new frequency to complete the system setup for operation.

Receiver ASC/IR Sync GR/CH (Frequency)

If different frequencies than previously stored in both the receiver and transmit- ter memories are needed, there are three ways to program the receiver and then sync the selected Group/Channel to the transmitter: One-Touch Automatic ASC™/ Auto Sync receiver to transmitter, manual SCAN for Group/Channel, or manual select Group/Channel from the Factory Preset or User Selectable channel. Place the transmitter’s IR RECEPTOR SENSOR WINDOW (37, 44) 6-12” away from the receiver’s IR WINDOW (4) before starting the following steps.

For One-Touch channel Autoscan and Automatic ASC™/Auto Sync from the receiver to the transmitter, press the MENU BUTTON (18) once, wait for about 5 seconds, the receiver will start process automatically with no further user action required. A running bar in a clockwise direction on the LCD DISPLAY (5) shows the scanning process which normally takes about two seconds. When it finds an interference-free channel, the receiver stores the channel for use, and it will begin

ASC™ sync IR download of the selected channel to the transmitter automatically.

To manually scan the selected Group/Channel, press the MENU BUTTON (18) twice for AUTOSCAN menu, press UP BUTTON (16) once and it will start scanning. A running bar in a clockwise direction shows the scanning process, which normally takes about 2 seconds. When it finds an interference-free channel, it will display and store the frequency/channel for use. It can be rescanned again for a new frequency by pressing the UP button or pressing the MENU BUTTON twice to IR MENU (IR icon will lit up for IR function), then pressing UP BUTTON to start IR programming.

To manually select Group/Channel press the MENU BUTTON (18) once for GROUP (11) selection for Factory PRESET Group 11 to 1A mode or User SELECT- ABLE Group 1B to 1F mode. Use the UP/DOWN Buttons to change the group. Af- ter selecting a group, press the MENU BUTTON twice for channel selection menu. Use the UP/DOWN Buttons to change the channels (frequencies) that are avail- able in each group. [Note: for Group11 to 1A, the CH (12) display will indicate the channel number chosen, and for Group 1B to 1F only the letter “U” and the frequency chosen will be displayed. See section “11. U-800 Frequency Lists” for available channels in each group]. After finishing channel selection, press the MENU BUTTON once or wait a few seconds for IR MENU, and then press UP BUT- TON to start IR programming.

This completes the GP/CH (frequency) programming. The next section outlines the procedure for sync’ing the receiver’s programmed channel to the transmitter.
