Q: A modem with "No dial tone" error?
If either get a NO DIAL TONE result code or cannot get modem to dial.
You will need to see if the software you are using has setting to have the modem ignore dial tone or add an AT command (according to your user menu) at the end of your initial string to have the modem ignore the dial tone.
If you sill are not able to dial out or get "NO DIAL TONE" error, one of the following may be the problem.
- The Phone line you are using is not working. Check with a telephone on the same line.
- You have too many devices on th eline. Try unplugging all other phone devices connected toyour phone line. Telling the modem to ignore dial tone may htlp.
- Your modem may not recognize the dial tone if you are oversea. Telling the modem to ignore dial tone may help.
- Your phone line may be plygged into the wrong jack. Make sure your phonoe line is plugged into LINE and your telephone is plugged into PHONE.
- Your modem may have been damaged. Please contact Harmony Multimedia techincal support for an RMA number so that the modem can be returned here for repair. Since the modem is exhibiting signs of power damage (which is not automatically covered under warranty), you may be charged for the repair of the modem.
Q: Modem cannot be found (detect) under Windows 95?
Use the following steps to narrow down and solve the problem.
- Check the jumper setting, make sure the COM and IRQ setting correctly.
- Check the modem, is it plugged in the slot properly?
After you install your modem, Window 95 should:
- Recognize your modem
- Assign a unique COM port and IRQ for your modem to use (if modem is PnP)
Use the following steps to narrow down and solve the problem.
1. In Windows 95, select Start, then Control Panel, then Modem, then Diagnostics, and then More Info.
- If Windows 95 can communicate with the modem, then the modem is functioning correctly. Check your software (Quicklink) to be sure it's set to the correct COM port.
- If Windows 95 shows an error message in the More Info box (something like " cannot open port"), goto step 2.
2. In Windows 95, select Start, then Control Panel, then System, and then Device Manager.
3. In Device Manager, if you see any yellow circle icons, remove them all be selecting on, clicking on Remove, until they are all gone.
4. Click on Modems in Device manager. Remove all modems listed be selecting one and click on Remove until they all gone.
5. Click on Ports in Device Manager. Remove all ports.
6. In Device Manager, if you have an item called Unkow Devices or Other Devices, remove all entries in this section by clicking Remove.
7. Verify that you have no modem, port, or "other device" entries in the Device Manager.
8. Select Start, then Shutdown, and turn off your computer.
9. Turn on your computer after 20 seconds. If the New Hardware Gound dialog box appears, you need to install a modem driver file. If the New Hardware Found box does not appear, means Windows 95 already has a driver for your modem. Then you are ready to use.
10. Click "Driver from disk provided by hardware manufacture."
11. Click OK.
12. Insert the Harmony Utility Disk in drive A: (use the appropriate driver if floppy drive is not drive A)
13. Click OK. Windows 95, select Start, then Control Panel, then Modems, then Diagnostics, and then More Info. If Windows 95 does NOT return an error message, the modem is functioning correctly. Your modem is ready to use. Restart your computer.
14. Eject the disk and store it in a safe place.
15. In Windows 95, select Start, then Control Panel, then Modems, then Diagnostics, and then More Info. If Windows 95 does NOT return an error message, the modem is functioning correctly. Your modem is ready to use. Restart your computer. Top
Q: My modem cannot reach the highest speed!
Full Duplex modems do support speaker phone function, it can send and receive voice/data at the same time. Unlike walkitalki, it will allow users at the ends of the line to talk at the same time. Most of Harmony modems support the Full Duplex speakerphone feature. Top
Q: Quicklink speakerphone function doesn't work!
Q: How to increase the speaker volume?
Type in "L3" in y our AT command mode. Using Quicklink Message Center software can run the AT command mode.
Q: What is the URL for Harmony Multimedia?
Q: How can I get the device driver from the web?
Q: How to set my modem be more sensitive?
Add "S10=1" at the end of the intial string. Top
Q: I cannot contact to the internet!
Make sure you set your modem properly. Top
Q: After trying all methods, the modem still doesn't work:
The driver may be bad, or you are using the wrong driver. Reinstall your modem again, if it still doesn't work. You can download a new modem driver from Harmony Multimedia Web page TECH SUPPORT/DRIVER. Top
Q: Aren't all 56K modems the same?
No. There are, unfortunately, two major, mutually exclusive 56K modem standards. Rockwell, Lucent, and a few other companies combined to promote the K56flex standard,w hile U.S. Robotics (now 3Com) has pushed its proprietary x2 standard. The problem is that x2 technology can only connect to x2 technology, and K56flex can only connect to K56flex. Neither side wants to compromise for one simple reason: The side whose standard is ultimately adopted will rule the modem market in the same way that Microsoft rules the desktop computer market. This maddening double- standard doubles the cost for all ISPs who offer 56K access. TECH SUPPORT/DRIVER. Top
Q: What is K56flex technology?
The new 56K technologies is the elimination of the analog loop at the Internet Service Provider(ISP). Since most ISP's access lines are digitally terminated, transmissions don't have to be converted back to analog. This elimateds one analog loop, lowers noise levels, and allows the higher transmission rates.
K56flex means substantially higher throughput in downloading Web pages, as well as improved perference of audio/video applications over the internet. K56flex technology offering up to 56K speeds over ordinary telephone lines. By allowing downstream speeds up to 56K from the ISP to user, K56flex significantly speeds up the delivery of information. Graphics- intensive Web pages, audio and video, and files will download at near ISDN speeds and at twice the rate of the precailing 28.8K standard. TECH SUPPORT/DRIVER. Top
Q: What is X2 (56Kbps) Standard?
X2 technology allows modems to receive data at up to 56Kbps over the standard, public switched telephone network(PSTN). X2 overcomes the theoretical limitations imposed on standard.
Typically, the only analog portion of the phone network is the phone line that connects your home to the telephone company's central office. Over the past two decades, the telephone companies have been replacing portions of their original analog networks with digital circuits. But the slowest portion of the network to change has been the connection from your home to the central office. That connection will likely be analog for some years to come.
X2 products are capable of 56Kbps downloads; howeverm, due to FCC rules which restrict power output of your service provider's modems, current download speeds are limited to 53Kbps. Actual speeds may vary depending on line conditions. An X2-capable analog phone line and X2 capable service provider are necessary for these high-speed downloads.
X2 technology is asymmetric. It sends and receives at different speeds to take advantage of the digital connections most ISPs have to the public phone network. TECH SUPPORT/DRIVER. Top
Q: What's wrong? When I set up my ISP and install my new modem. The first call I place to my ISP isn't at 53 or even 40Kbps but a measly 28.8-Kbps or slower connection.
Signals from 56K modems are delicate. They tolerate only one analog-to-digital conversion along your phone line. In most cases, the signal from the line is converted from analog to digital only once, at the phone company's central office, and from there it travels to your ISP, which has a digital connection.
But many phone lines, particularly in high-population growth areas, are multiplexed together(meaning they share one connection) using a device called a subscriber line concentrator, or SLC. If the SLC is able to connect digitally to the phone company's central office, it makes only one conversion. Many older central offices, however, can connect to an SLC line only if the signal is converted to analog form first. Then the central office reconverts the analog phone signal to digital network. The result of two conversions a signal that's too noisy and distorted to work at 56K. Similarly, 56K will not work through the conversion commonly done in a hotel or business telephone system. So in most cases you can give up the dream of achieving fast connections form the office phone or when you are traveling. Top
