loader. When the key is loaded in
the key loader, press the PTT on the
key loader. The R2670 should
respond with the “External Key
Loaded” message. IF the key does
not load, follow instructions in this
manual under “External Key Load
Failed” message. If the key loads
successfully, reselect the EXT KEY
softkey in the SET UP menu.
External Key Load Failed
An attempt to load an External Key
with a key loader has failed.
qwdId:
Observe the SET UP menu in the
Display Zone. Verify that the
selected algorithm matches the key
loader type. For example, if the key
loader is a DVP-XL type, verify that
the SET UP menu displays
“Algorithm Sel: DVP-XL.” Also,
verify that the selected key type is
EXT KEY.
On the back of the key loader, verify
that the key loader type is DX or any
KVL 3000 with the ASN option.
Check the connection from the key
loader to the R2670 then retry the
key load. IF the key load continues
to fail, perform an encrypt reset
from the Special Functions (SPF)
menu. After the reset, retry the key
load. If the key load still fails,
contact the Service Representative.
Entry Field Must Be Made with Mod
OFF
An attempt to change the embedded
data fields has been made while the
R2670 is generating Project 25
VOICE.
qwdId:
In the Audio Zone, turn off the
Project 25 signal by changing CONT
to OFF before attempting to change
the embedded data fields.
Encryption Algorithm Mismatch
An attempt has been made to receive
voice in an encryption mode that is
different from the encryption mode
used for transmitting the voice.
(This error only occurs when the
analyzer is in monitor mode.)
qwdId:
If the message is displayed and clear
voice is heard, then the encryption
needs to be turned off on the setup
page. If the message is displayed
and garbled voice is heard, then the
encryption type selected on the setup
screen needs to be changed to the
same encryption type used for
transmitting the voice.
L-1.2 Project 25 Error Messages
The following three messages are very
similar. They are all related to a severe
failure of the Project 25. A general
discussion of the cause follows, along
with a general recommended solution.
This solution is basically to reset the
R2670 and restart the powerup sequence.
PROJ 25 Failed, Notify Local Service
Rep
PROJ 25 Option-Illegal CP Request
PROJ 25 Option-Bad CP opcode
While in the Project 25 mode, the
system experiences difficulty when
communicating with the Project 25.
