UPGRADING CS700 TO CS700A
AND
UPGRADING CS700 TO CS750

To upgrade from a CS700 to a CS700A requires the following steps:

1. Get a copy of the tuning parameters.
2. Take the radio apart to get to the PCB
3. Short two points on the PCB and turn on Power
4. Load New Driver
5. Load New Firmware
6. Convert new tuning parameters to new turning parameters
7. Use service Monitor to tune certain parameters if necessary
8. Initialize code plug

There are three issues with having the customers do this themselves.
(1) If you make a mistake you might brick the radio and could take at least 4 hours to recover.
(2) If you short the wrong spot on the radio you might damage the radio.
(3) We have no way of protecting our intellectual property from being copied by other manufacturers.

Connect Systems decided that because we cannot have the customers do the upgrading themselves because of the above reasons, we would charge a nominal fee of only $20 including shipping within United States to upgrade an old CS700 to the new CS700A. For customers outside the United States, we will charge $15 plus shipping. For those customers it would be advantageous to ship multiple radios at the same time.

To Convert the CS700 to a CS750 requires the changing of a memory chip. This means unsoldering an existing IC and soldering in a new IC. Then you following the above 8 instructions. For that the price is $60 including shipping. For customers outside the United States, we will charge $55 plus shipping. For those customers it would be advantageous to ship multiple radios at the same time.

To upgrade your radio call (818) 889-0503 after the Dayton Hamvention for a RMA number. With the RMA number, you must include the radio, your return shipping address, and a check or credit card number to cover the cost of upgrade.

CS700A

The CS700A is the old CS700 Hardware with some new firmware. Among some of the features in the first version of the CS700A is programmable Mike Gain and Nuisance Channel Delete. Future updates will have some of the other features I promised a long time ago. If you are happy with the CS700 you have now, there is no compelling reason to upgrade your radio. The outside of the radio is still marked CS700.

CS750

The Original CS700 was designed for the commercial markets and as such did not have certain features that was desired by the Amateur market. The CS750 is the first DMR compatible radio to be designed specificially for the Amateur market. In the commercial market, having one thousand contacts is probably more than you will ever need. There is nearly 10,000 contacts available just in the DMR-MARC network and all those contacts and more can be stored in the CS750. The Papa Amateur Club has nearly 1000 channels covering its repeaters up and down the California coast. Our radios will have more than 1000 channels. The Amateurs have a need to add channels while away from their computers. The CS750 will have keypad programming. Some of the other features that the Amateur Community has asked for will be in there such as Nuisance Delete and Mic Gain. More features will be added as we get feedback from the Amateur Community. The price for this radio is $239 if ordered directly from Connect Systems. The price is $229 if your order 10 or more at the same time. You will also save on shipping cost per radio. Some of the features described will not be available on the first release but will be added by a simple upload of new firmware. To order please call (818) 889 0503
