PROGRAM TIMER
WARNING : (For U.S.A. only)
This equipment generates, uses, and can radiate radio frequency energy and if
not installed and used in accordance with the operating instructions, may cause
interference to radio communications. It has been tested and found to comply
with the limits for a Class A computing device pursuant to Subpart J of art 15
of FCC Rules, which are designed to provide reasonable protection against
such interference when operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause interference in
which case the user at his own expense will be required to take whatever
measures may be required to correct the interference.
FEATURES
The TT-104B is a program timer having 4 independent output channels.
Weekly program capacity is 30 steps per channel, and each step can be programed in an increment of 1
minute.
A channel assignment switch turns B, C and D outputs into A output.
rograming, its change or cancellation can be performed easily and precisely through individual key
operation and display.
Setting the pause mode allows no program output to be delivered.
Output is a no-voltage make contact that connects for five seconds at the programed time.
Built-in buzzer audibly warns the user of key operation error.
Monthly error is ± 5 seconds at 25 °C of ambient temperature.
Clock and stored programs can be maintained for approximately 100 hours in the event of power outage.
INSTALLATION PRECAUTION
Do not switch power on and off frequently because this can shorten the power-outage backup time.
Be sure to set the memory backup switch to ON after installation.
Do not install unit close to a warm air vent or in locations where the unit is exposed to the sunlight.
Installation in high temperature areas like on the amplifier makes a clock inaccurate. Install the unit in the
area of which temperature is as close as possible to the room temperature.
Install the unit as far as possible from a radio tuner or a wireless microphone.
Be sure to ground the unit.
Be sure to unplug power cord from the wall outlet when making connections.

SETTING THE CURRENT TIME
1. lug power cord in wall outlet. Set the program switch to O ERATION. The clock display flashes to show
"0000" and at the same time, a warning tone beeps, indicating that the timer has to be set for current hour.
2. Set the rear-mounted MEMORY BACKU switch to ON. The switch allows a clock to work and protects
stored programs during power outage, but no timer output is delivered.
3. ress the DAY setting key (from Monday to Sunday) with the ADJUST key continuously pressed to set a day
of the week. The corresponding date indicator comes on, while a colon (second indicator) in indication
"00:00" that appears in the clock display begins to flash at time intervals of one second, indicating that a clock
is working. The beep stops.
4. ressing the ADJUST key continuously, press the clock settings (HOUR and MIN. keys) to set a clock for
current hour. The number increases by one each time the setting is pressed. If the unreal hour is set which is
not in a range from zero hour (00:00) to 23 hundred 59 hours (23:59), both the date indicator and clock
display flash and at the same time, a warning tone beeps. In such a case, correct the hour.
5. ress the 00 SEC. key, while pressing the ADJUST key continuously. This resets the second of a clock to
"00". ressing the 00 SEC. key when a clock second accounting is between 30 and 59 seconds increases
the minute indication by one. The minute indication does not change when the second is between 0 and 29
seconds. (The clock display shows no second, but the clock is working in second.)
HOUR CORRECTION
Check to confirm that the program switch is set to O ERATION. ressing the ADJUST key continuously, press
the clock reset key the moment the radio time signal tells zero second. This allows the clock to be timed to the
moment if variation is within ± 30 seconds. If the clock varies more than 30 seconds, use the time adjustment
as well as clock settings so that the clock display indicates the correct hour.
The second of the clock is not reset to zero second even when a day of the week and the current hour are set.

OPERATION
ROGRAM REGISTRATION
The output of the TT-104B is a relay contact that makes for five seconds at the programed time. The relay
contact cannot be kept connected or disconnected by programs. Take care that equipment to accept the pulse
output are connected to the timer.
1. Enter programs in the program table supplied with unit. Lump the programs together per equipment
connected and assign the output channel to each equipment. If the same equipment are used but their
programs are not the same, assign different output channels.
Example.
If it is so programed as to sound a chime both in the morning and in the afternoon of Monday through Friday,
and in the morning of Saturday, and to play a piano accompaniment to the morning announcement every
morning from Monday through Saturday, write on the table as follows:
