Turn BATT switch ON.

3-13. SETTING THE PROGRAM CLOCK WITH TIME OFFSETS. The ADV TIMER

button is used to preset the receiver clocks to real time (as determined from time

standard WWV or similar source). It can also be used to preset the receiver with a

start time offset. Each time the ADV TIMER button is pressed, the receiver program

clock timer will advance by one minute from its previous setting. This is done so that

individual transmitters can be distinguished from each other by different start time

offsets. The ADV TIMER button operates only on the particular path program timer

selected by the MODE switch in one of the three SET positions; i.e. if the MODE

switch is in SET 1, only the path one timer is affected by the ADV TIMER button.

Note that timing offsets are defined as the time that a sweep starts after an integer

5 minute interval of a real time standard. For example, if the start time offset is

2 minutes and 20 seconds, the sweep programmed for the 00 minute segment will start

at 02:20 real time, and the 05 minute program sweep will start at 07:20 real time, etc.

Follow these steps to begin a sweep with a timing offset:

a. Place the MODE switch in the SET position for the path timer desired (for

example SET 1) , and press RESET.

b. Determine how much time the start of the sweep is to be offset. For example,

assume the offset will be 2 minutes and 20 seconds.

c. Establish accurate real time by tuning to a time standard (WWV) or using

digital watches to note the minute and second.

d. Carefully note when the watch or standard reaches 00 seconds of a minute,

Note what the minute is, for example, 16 minutes past the hour.

e. Count 20 seconds (for this example) after the 00 second on the watch. When

it reaches 20 seconds, press the START button. The clock time will now start count-

ing on the 6025 LED display.

f. Press the ADV TIMER button to set the minute counter on the display to the

real time (from digital watch or WWV) minus two minutes (for this example). Thus,

if it was 16 minutes past the hour the ADV TIMER button must be pressed to read

14 minutes on the display.

The clock is now offset 2 minutes and 20 seconds from real time. You can

check this by comparing the 6025 timer display with WWV or a digital watch when the

display reaches a minute mark.

3-14. SETTING PATH 2 OR 3 CLOCK RELATIVE TO PATH 1. It is often convenient

to coordinate path clock timing with path 1 as the master reference and path 2 and 3

set with a defined delay offset relative to path 1. For example, path 2 clock starts

four seconds after path 1, and path 3 clock starts 10 seconds after path 1. To set

path clocks 2 or 3 timing relative to path 1 follow these steps.

a. Make sure path 1 clock is running and properly synchronized as the master

reference.

b. Place the MODE switch in SET 2 position, and then press RESET. Clock time

display will read 00:00 and path number will show a flashing 2.
