Move the cursor down to the command line. Enter
the desired command. The R2008D/R20IOD will
echo back a mnemonic describing the command. If
the particular command requested requires addi-
tional bytes, dashed lines indicate where they should
be entered on the screen. See figure 10. If this is the
case, move the cursor over to the dashed lines and
make the necessary entries. If hexadecimal data is re-
quired, use the normal 0-9 keys, but in addition, use
the 'up/down' keys, of DISPLAY, FUNCTION and
MODULATION to obtain A-F. The 'up/down' keys
of DISPLAY are used for A and
B.
The 'up/down'
keys of FUNCTION are used for C and D. The 'up/
down' keys of MODULATION are used forE and F.

MANUAL TEST DISPLAY
To send the command to the transceiver unit, return
the cursor to the home position and enter a '2'. The
command will then be sent along with any additional
bytes required. The operator is now free to send addi-
tional commands or to exit the screen and measure
parameters using the other R2008D/R2010D test
modes.
If the command sent requires that the cellular tele-
phone return information, the R2008D/R20IOD will
display the returned data automatically.
If
failures occur in this handshaking procedure, an
error message is displayed on the bottom of the
screen.
Normally, the first command entered is an Ol com-
mand {SUSPEND) to set the transceiver into the test
mode so that the other commands can be utilized.
Otherwise, only STATUS, TURNAROUND, RE-
SET, RESTART and SUSPEND will function.
Repeats of the same command can be made by multi-
ple entries of '2' while the cursor is in the home posi-
tion.
For a list of the 43 possible commands, see appendix
F.
