If the analog telephone works on the line, try using it with the EF2201 to dial manu-
ally. Connect the L jack of the EF2201 to the telephone jack in the wall, and con-

If you can make calls by dialing with the analog handset, but not with the remote con-
trol device, that means there is a problem with the remote control. See the "Remote
Control Problems" section below.

If the remote control device doesn't seem to be affecting the EF2201, there are a few
things you can check. Try sending commands that have a visible impact, like the
PHONE command (which turns on the front panel P
sages from the EF2201, like acknowledgement or error messages, if the remote con-
trol device can display them.
Make sure the commands that are being sent to the EF2201 have the correct syntax.
If only a couple of the commands aren't being processed, there may be an error in the
syntax of those commands. Remember, the commands are case sensitive. The
EF2201 should return ERROR# messages if the commands are typed incorrectly, as
long as error messages are enabled.
Make sure the Device ID of the EF2201 matches the Device ID of the commands that
are being sent. If they don't match, the EF2201 will ignore all the commands. Try
sending a command to all devices (*** instead of Device Type and Device ID). If
this works but sending commands to a specific device doesn't, the Device ID doesn't
match.
Make sure the RS-232 cable is connected securely to the EF2201 and the remote con-
trol device. The RS-232 cable should be connected straight through. Do not use a
null modem.
