NOTE
The alarm time is now set to 2:45 pm. The alarm
will go off everyday
at 2:45
pm outputting
the
negative
going TTL level pulse to the ALARM/
SERIAL
IN connector.
To verify that the alarm time was set to 2:45 pm by the pre-
ceding
example,
press PRGM, 7 and the display
shows that
the alarm time was set to 2:45 pm.
NOTE
Upon
power-up
or upon
activating
front
panel
Program
99, the Model 705 sets the alarm time
to 00.00.00.
When
the Alarm
time
is set for
00.00.00,
no pulse appears.
2.6.9 Program 8 Self Test
Program
8 is used to run a test on the ROM, RAM circuitry
and also to test the front panel
LED's
This test is also per-
formed
upon power-up.
If it is desired
to run the test without
powering
the unit down then up, Program
8 can be used. Use
the following
procedure
to activate
Program
8.
1. Press PRGM (selects program mode).
2. Press 8 (selects program 8).
Once step 2 is completed
the Model 705 performs
the follow-
ing sequence:
First the Model 705 turns on all the segments
in the display
as shown:
This is a display
test. The operator
can note inoperative
dis-
play segments
by comparing
the Model 705 display
with the
figure above.
In addition,
the push button and the TALK, LIS-
TEN, and REMOTE
indicators
turn on. All indicators
are on
simultaneously
if operating
correctly.
While all the LEDs are
on, the Model 705 is performing
a cyclic redundancy
check
(CRC) of the ROM circuitry. A digital self test of the RAM cir-
cuitry
is also performed
at this time. If the digital
self test
reveals
a problem
with the RAM circuitry
the Model 705 dis-
plays the following
for approximately
0.5 seconds.

After this display the Model 705 displays

If the CRC
reveals
a problem
with the ROM
circuitry
the
Model
705
displays
the
following
for
approximately
0.5
seconds.
After this display the Model 705 displays
the following:
If the self test
and the
CRC
both
reveal
a problem
the
Model 705 displays
the RAM and ROM error messages
and
then displays
the fail message.
When either
test does
not reveal
a problem
the Model
705
displays
the following
message
which
indicates
both tests
have passed:

2.6.10 Program 90 Stand Alone
I
Program
90 is used to program
a Model 705, out of the Mas-
ter and Slave programs
and into normal front panel operation.
1. Press PRGM. (Selects program mode.)
2.
Press 9, 0. (After pressing the 0 button the Model 705 dis-
plays the following two messages
and reverts to the channel
mode. The channel LED turns on and the channel previously
displayed before pressing PRGM is displayed.)

Program 90 takes the Model out of the Master condition
and
also out of the Slave condition.
Program 90 also set the pro-
grammed first channel to 1 and the programmed
last channel
to 1.
NOTE
After actuating
Program
90 cycle
power
to the
instrument
or activate
Program
99 in order to set
the instrument's
ALARM/SERIAL
IN connector
to alarm output.
2.6.11 Program 91 Master
Program
91 sets the Model
705 as the master
control
of a
daisy chain configuration.
The designated
master
Model
705
is the only unit in the configuration
that has front panel con-
trol. All the controls
on the front panel control
the master
unit
as well as the slave units of the configuration.
