1. All boxes are tested at 13.8 volts to insure that they are 100% before they are shipped!
2.Wire size is very important to your set-up.
3.The FM 1 should be a no. 10 wire or larger.
4.The FM 2 & FM 2-1 should be a no.8 or larger.
5.The FM 4 & FM 4-1 should be a no.6 or larger.
6.The FM 4-2 & FM 6 should be a no.4 or larger.
7.The FM 6-2, FM 8 & FM 8-2 Should be a no.2 or larger.
8.If you are running more than 12 feet of wire, we recommend that you go to the next larger size wire.

9. ALWAYS MAKE SURE YOUR ALTERNATOR IS LARGE ENOUGH!!
10. We recommend that you run a extra battery(s) for the FM 4 (if driven) and larger boxes, if you want to see the most out-put.
-
11. Radio or driver set up is very important. Always make sure that the DEAD KEY is set correct.
12. WE recommend that you NEVER allow your box to key more than 80% of the combined total of the main transistors.
13. Example- the FM 2-1 has 2 main 120 watt transistors. 2x120=240x.80=192 watts max dead key (less is better).
14. Example- the FM 4, 4-1 & 4-2 have 4 main 120 watt transistors 4x120=480x.80=384 watts max dead key (less is better).
15. MAKE SURE YOUR ANTENNA WILL HANDLE THE WATTS!!
16. MAKE SURE YOUR BOX IS WHERE IT CAN GET GOOD VENTILATION!! (NEVER inside of a closed box or compartment!!)
17. Most boxes do not come with a fuse. We recommend for you to use a LARGE fuse holder (with the proper size fuse for the size box you have) at the battery, so the wire and box are protected!!
VOLTING
1. We recommend that you never hook your box to more than 15vdc.
2. If you choose to do so then there are several things you need to remember.
3. IF YOU WANT TO PLAY-THEN YOU HAVE TO PAY!
4. NEVER VOLT A BOX THAT DOES NOT HAVE 2sc2879,s TRANSISTORS AS THE MAIN TRANSISTORS.
5. Your box is set-up at 13.8 volts.
6. If you increase the volts, you will increase the chances of burning out your Transistors, Fan, Relay &etc.
7. A voltage regulator will have to be installed for the fan or the fan changed.
8. When high volting a box, we recommend that when possible to increase the volts and/or dead key slowly to give the transistors time to warm up!
9. WATCH YOUR DEAD KEY. 80%
Some Test Results.
1. We can tell you this--a FM 2-1 keying 150 watts at 18vdc SHOWED no sign of damage for 6 weeks of normal usages.
2. A FM 4-1 & 4-2 keying 300 watts at 18vdc, SHOWED no damage after 2 months of normal usage!
3. A 4-2 keying 800 watts at 20vdc, lasted for 2 hours of heavy usage
4. A FM 2-1 volted at 25volts keying 400 watts will last 3 seconds!! GOOD LUCK!!!
