From CASIO FAQ:

How do change the currency rate?

When you press the [M/EX] key, it toggles between conversion mode and memory mode. You will see "EXCH" on the display when in conversion mode.
C1, C2, and C3 are three conversion rates. C1 is your home country currency, and so it is always set to 1. C2 and C3 are rates for two other countries, which you can change.
For example, if you want to set a conversion rate of \$1 to 0.95 euros, here is what you would do (using C1 for US dollars and C2 for euros):
1. Press [AC]
2. Hold [SET/%] for about two seconds until "SET" appears
3. Press [C2] to select currency 2
4. Input the conversion rate (0.95) and then press [SET/%] to store it in memory
You can check the currently set rate at any time by pressing [AC] and then [C2].

How do I perform a currency conversion?

If you want to convert 100 euros to US dollars, you would do the following (assuming you are using C1 for US dollars and C2 for euros):
1. Press [AC]
2. Enter 100 and then press [C2]
3. Press [C1] to convert to dollars
4. To convert back to euros again, press [C2]
You can also perform a currency conversion within a calculation. How much in US dollars would five items selling at 100 euros cost?
1. Press [AC]
2. Enter 5 [×] 100 and then press [C2]
3. Press [C1] [=]

### What would be the best settings on a pyramid arctic 1000 watt amp for one JL audio w1 12

Your sub is a 4ohm woofer, running it in bridged mode + on right connection - on left connect as market on sub will give the best output. Your sub is rated at 75w to 300w and in this configuration will be getting just over 100w which about all the amp can provide with your sub/amp combo.
I don't know where they get the 1000w rating from either? the maximum the amp can possibly provide is 150w if running a 2ohm woofer in bridged mode.

### Hi, Can any body help us? We have a M7324 on a Norstar Compact with two line pools, Pool A is on Line 1,2,3 and Pool B on Line 4,5. We want to add another line on Pool B so I tried configuring Line 6 which...

On the cross connect do you have a CO connected to that line. That is most likely the cause of no dial tone. If you don not know how to check that call a phone system expert to connect and verify your system.

### Lost instructions. How do you change value of tax

The c1, c2, & c3 are for exchange rates. To set the c2 exchange rate press AC. Press the MODE M/EX button till EXCH appears in the display. Press and hold the SET/% button for a few seconds until SET EXCH appears in the screen. Press c2, C2 SET EXCH RATE should be displayed. Enter the desired echange rate. For instance, today, Thai Baht is 32.8677. Once you enter your desired exchange rate, press the SET/% button.

To convert 100 dollars using the exchange rate you set on c2, make sure that EXCH is in the display by toggling the MODE M/EX button. Press AC, enter 100, press c1 then c2. Using 32.8677 as the exchange rate 100 dollars would be 3286.77 THB.

To convert 100 THB to dollars you would enter 100, then press c2 and then c1 yeilding 3.04 dollars.

You can also program a different exchange rate into the C3 button. To convert to that currency, you press c1 then c3. To convert from that currency, you press c3 then c1.

Hope that helps
