I searched the internet and did not see a manual for this vintage calculator. One might show up eventually on sale if you search at a later time, but that is an old model.

The following ebay site is said to have a complete unit in an original box which is likely to have a manual. You could try contacting the vendor, and offer to purchase a copy of the manual, if there is one inside the box.

Graphing on a Number Line
Integers and real numbers can be represented on a number line. The point on this line associated with each number is called the graph of the number. Notice that number lines are spaced equally, or proportionately (see Figure 1).
Figure 1. Number lines.

Graphing inequalities
When graphing inequalities involving only integers, dots are used. Example 1 Graph the set of x such that 1 ? x ? 4 and x is an integer (see Figure 2).
{ x:1 ? x ? 4, x is an integer}

Figure 2. A graph of {x:1 ? x ? 4, x is an integer}.
When graphing inequalities involving real numbers, lines, rays, and dots are used. A dot is used if the number is included. A hollow dot is used if the number is not included.
Example 2 Graph as indicated (see Figure 3).
1.Graph the set of x such that x ? 1.
{ x: x ? 1}
2.Graph the set of x such that x > 1 (see Figure 4).
{ x: x > 1}
3.Graph the set of x such that x < 4 (see Figure 5).
{ x: x < 4}
This ray is often called an open ray or a half line. The hollow dot distinguishes an open ray from a ray.

Figure 3. A graph of { x: x ? 1}.

Figure 4. A graph of { x: x > 1}

Figure 5. A graph of { x: x < 4}
Intervals
An interval consists of all the numbers that lie within two certain boundaries. If the two boundaries, or fixed numbers, are included, then the interval is called a closed interval. If the fixed numbers are not included, then the interval is called an open interval. Example 3 Graph.
1.Closed interval (see Figure 6).
{ x: -1 ? x ? 2}
2.Open interval (see Figure 7).
{ x: -2 < x < 2}

Figure 6. A graph showing closed interval { x: -1 ? x ? 2}.

Figure 7. A graph showing open interval { x: -2 < x < 2}.
If the interval includes only one of the boundaries, then it is called a half-open interval.
Example 4 Graph the half-open interval (see Figure 8).
{ x: -1 < x ? 2}

Figure 8. A graph showing half-open interval { x: -1 < x ? 2}.

Most likely not. Clock should have backup battery.

That appears to be a brand new motor home as opposed to a piece of Office Equipment! I thought black tanks had to be pumped out? Contact the maker under warranty.

stating MG5700 series is correct. Your problem is the USB001 part. Although this printer can run via USB, it is primarily a WiFi network printer.

Hi-Speed USB (B Port)

Wi-Fi: IEEE802.11 b/g/n

Wireless LAN Frequency Band: 2.4GHz

Please refer to the user manual for instructions on how to activate/deactivate the wireless LAN.

Reinstall software and Drivers. Then decide if you are using USB connection or WiFi. Run Setup. Using Wifi, you can print via your smartphone using the Canon Print App

SORRY BUT IF THE UNIT DOES NOT HAVE THERE IS NO FIX

Did you put it back exactly like it was before? Are you sure all connections sit ok?
Were you safe with E.S.D. (Electro Static Discharge).
Because handeling with bare hands could damage any electronic chip.
I'm afraid you need the help of an expert to solve your problem.
