SECTION 1: MAKING THE RIGHT CONNECTIONS
1.1
Plug the power adapter (supplied) into an unswitched 120 volt wall outlet and plug it into
the power jack on rear of the DMR 'S'. The LED indicator lights on the front panel will be
illuminated indicating that there is power.
1.2
Make sure the battery BACKUP switch, located on the rear panel, is in the ON
position. This will ensure that messages won't be accidentally erased, even during
extended power disruptions (or as long as 20 days). Once power is re-established,
the internal backup system will recharge automatically. If you plan to store the DMR 'S' for longer
periods, this switch should be turned OFF to preserve the internal battery. Remember to turn it
back ON before putting the unit back into service.
1.3
Leave the DMR 'S' plugged in overnight with the BACKUP switch ON to ensure the backup
system is fully charged. (The DMR 'S' will act erratically if it has not been sufficiently charged.) It
is advisable to allow the unit to charge in this manner after any extended period that the DMR 'S'
has not been plugged in.
1.4
Finish making the rest of the connections as illustrated in the CONNECTIONS DIAGRAM.
If you are using optional equipment refer to the literature supplied with that equipment for
additional connection details.
