The control panel contains two keypad areas that can be used to communicate to the projector: a 4X4 numeric keypad area
on the left, which contains numeric and some function keys, and a 3X3 command keypad area in the center, which
contains keys that execute the most commonly used functions. The numeric area can also be used for some commands.
In addition, hexadecimal representations above 9 (A - F) can be entered from the numeric keypad area, as shown in Table
2.2. These keys are used to enter values in base-16 notation.

The LEDs associated with the keypad provide an indication of projector status. Table 2.3 contains a list of the keypad
LEDs and their indications.
Upon detection of a malfunction that causes a NOT READY condition, one of the <0> – <6> LEDs or the <CLEAR>
LED will latch on, indicating the cause of the fault. These indicator LEDs can be reset once the <NOT RDY> button has
been pressed and the cause of the malfunction has been corrected.

The frame counter is normally displayed here. As explained in Section 0, this is a composite measure of elapsed time
(hours + minutes + seconds) and frame count within a second, expressed in the standard counter format hh:mm:ss:ff.
Some of the 35/70 projector operating and diagnostic commands use positions on the frame counter LED display to
display values or echo input for verification. Refer to the individual command write-ups in Section 0 for detailed
explanations of these instances.
