Problem: receive modem READY LED not on

If the DW4020 is not operating normally and the receive modem’s READY LED is not lit, as shown in Figure 65, take the following steps:

•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 66. If the power cord was loose, the receive modem READY led will come on when power is restored.

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

•If the Receive 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.

Note: Often, if the receive modem READY LED is not lit, the other modem LEDs will not be lit either.
