Connect the Radio Modem Aerial to the Radio Modem.
Connect the appropriate cable to the Radio Modem (for
example the 14C0038A connector J3 for the RT3000).
To make sure that the Radio Modem is receiving correc-
tions from the RT-Base look at the LEDs. The Table
below gives a description for some of the LEDs on the

Receiving a packet
The Remote Radio Modem should receive a packet (RD
and CD both green) once per second, with a slightly
longer packet once every 10 seconds.
Step 5 – Charging
The battery in the RT-Base will last more than 10 hours
when fully charged. To recharge the battery connect the
RT-Base unit to a mains supply for at least 2 hours.
RT3000 Connection
The connection of the Radio Modem to the RT3000 is
shown above. Most of the RT3000 User Cables have J3
as the Radio Modem connection; check in the RT3000
manual if you are unsure.
