Transmit modem READY

LED not lit

If the transmit modem is not operating normally and its READY 
LED is not lit, as shown in Figure 47, take the following steps.

•

Check that the receive modem READY LED is continuously 
lit. If not, try the sequence in 

Problem: receive modem 

READY LED not on

 on page 55.

•

Check that the 25-pin connector is attached securely. See 
Figure 46.

•

Check to make sure the power cord is securely attached to the 
receive modem and plugged into the wall outlet or surge 
protector. See Figure 46. If the power cord was loose, the 
transmit modem READY led may come on.

•

If securing the power cord does not solve the problem, check 
all cable connections. Tighten any that seem loose.

•

If the transmit modem READY LED still does not come on, 
power cycle the DW4020 by unplugging the power cord from 
the wall outlet or surge protector, waiting ten seconds, and 
plugging it back in.

•

If the problem persists, contact technical support.
