1.Introduction Digital Modem can encode/decode BPSK31/63, RTTY, QPSK and CW modes without PC, specially for portable digital communication 。 With its internal high performance DSP chips can process radio data。Internal SD card can save the regular Logs and real time audio data(Including FFT data). Its external USB host interface can be used for a USB Keyboard 。...

(Higher volt lower current is required) DO NOT reverse battery polarity , DO NOT charge AAs。 Diagram of Battery replacement: Screw down three of them in both sizes。 ===================================== AA battery is better for outdoor use。 Lithium battery is long life for use. But will lose its capacity for long keeping.
3.Digital Mode operations 4.1 Receiving Firstly, ensure your wire connection is all right 。 Turn on power of digital modem(Press B1+B2 for 1~2s ),If there is FFT spectrum display. Congratulations, Receiving is OK 。Easy work, (Some radio needs to turn OFF SQL) appropriate MODE(see Appendix...
3.3 Practical use First find the data communications sound on radio, and align with the cursor on the crest range of about 2 grids, the machine will automatically lock and calibration signal. If the mode is no error, the decoded information will soon appear at the bottom of the screen.
3.4 Macro With skillful use,Users need to be given a lot of tedious and type of input and simplify operations, this time you need to use a macro 。 Through a series of macro includes a switching transmitting/receiving, content input and other operations defined on the F1 ~ F10, when using only need to enter F1 ~ F10 machine will perform a series of actions that you set in advance。...

5.Upgrade firmware About upgrading firmware, mainly to allow supports some new features or fix some BUG, it is an important aftermarket product support means. A good product is capable of continuous appreciation or hedging products. Spend the same money to buy more and more, or improve the function, rather than developing completely on the matter.
