a reinstallation of the unit, if you are unsure of the configuration or if you are having
other problems with the unit.
Press <CTRL>+<F5> then <Y> then <ENTER> to perform Reset RAM operation.
The Unit will initiate a Self-Test after the values are reset.
4.7 Initializing the Subscriber Unit
Having programmed the unit, you are now ready for a final check. Plug in the
handheld programmer if available. Push the Reset button on the controller board
(See Diagram 3). At this point, the message on the programmer should read:
SELFTEST - PASS
SUB [rev#] 7788F
ID#:NNNN (C) [date] AES
If a "Fail" error message other than 001, 101, 300 or 301 is displayed, push the reset
button. If the error persists, refer to Section 3.8, which contains a list of error codes.
The status lights indicate the progression as the subscriber unit goes on the air and
attempts to enroll into the network.
Details of automatic Network log on sequence after a reset:
 STATUS INDICATOR LED's RX, TX and WA lights come on briefly,
testing the LED's.
 RX comes on briefly during loop back test (a self test).
 TX comes on sending a "Receiver Not in Service" message - AL + WA blink
at different but steady rates.
 TX comes on as unit transmits a "Request for Reply".
 WA stops flashing after about 15-30 seconds if one or more other subscriber
units reply to the "Request", (otherwise the WA continues to flash, indicating
the unit is not on the network).
 TX comes on again (if WA stops flashing) to send first message.
 AL blinks at a steady rate, indicating a normal condition.
 When the unit receives a valid acknowledgment, the WA light turns off.
This indicates that the reset or powered up 7788F unit is now on the network.

IMPORTANT NOTE: A flashing WA light (blinking at a steady rate) indicates that
the subscriber has NOT linked itself into the network.
If enrollment fails, check antenna and all cables; be sure that correct system cipher has
been programmed in to the unit. Once the Subscriber is enrolled in its network,
additional testing can commence. At this point, with the WA off, the Subscriber has
passed the initial RF operational test.
