The following steps serve as a guide to the operation of the Lightweight Digital fAX with the RT-1523(C)/U or
a . Load paper to be faxed.
b . Press MEMORY LOAD.
d. Press Establish contact.
e . Receiver presses RCV switch.
f . When tone is heard, sender presses RCV switch
g. When RCV light goes out, receiver presses RCV switch
h. On the TRT-1523(C)/U system, If the copy received is not good, or if working at exttending range
change the RT data rate to 1200
System Trouble Procedures. These steps will assist you in isolating fault system components when
you have a problem communicating in a not using data transmission. These Procedures assume that the net
and secure FH voice communcating has been established. IFyou are unable to communicate using data
transmission, do the following troubleshootng steps in the order provided:
CHECK LOCAL RADIO. Use the data on the FH voice net to determine that the radio net is operating
CHECK WITH OTHER NET MEMBERS. Do you have data communicatiion with some station s but
not others? The other stations may be out of range, temporarily off the air or has not cheched into the
net. If data communication can be established with another station, your system is probably OK and
the problem may be at the distant net station
CHECK SYSTEM CONFIGURATION. Verfy proper cabling, initialization and subscriber parameter
radio set and Lightweight DIGITAL fax switch setting etc.
NOTIFY MAINTENANCE. If the problem cannot be isolated, notify unit maintenance personnel and
inform your NCS of your communication problem.
8 . Remote Control Operations. The Remote Control Unit (RCU) C-11561 may be used in place of the RT IN a
SINCGAR radio system to allow the radio set and antenna to be placed at distances up to 4km from the local
system. Interoperabilility between the Lightweight Digital FAX and the RCU is the same when the Lightweight
Digital FAX is connected to an RT. Table 8-1. provides the switch setting s for the radio set and the RCU
remote control operation
4800 (high speed)
1200 (extended range)
