OPERATING INSTRUCTIONS

PROGRAM TIMER

TT-104B

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 Part 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.

Programing, 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.

for the current time.

00 SEC. key-Use this key to adjust a clock to
seconds. As soon as the key is pressed with the
ADJUST key pressed continuously, the clock is
reset to zero second and a new counting of
second gets started. Pressing the key when the
clock counting is between 30 and 59 seconds
automatically increases the minute indication by

The 00 SEC. key works only when the program switch is

set to OPERATION.

pressed continuously. This setting is also used to set the
time of the timer program.

Each time the TIME key is pressed, the number over

the setting pressed increases by one.

Day setting keys-to program a current day of the week into the

timer, press this setting with the ADJUST key pressed continuously.

This key is also used to register the day of the week of timer

program.

Program switch-Set this switch to OPERATION when setting a clock for the
current hour or when letting the timer work. Set the switch to PROGRAM to

CHANNEL key-Use this key to select the
program output. Pressing the key causes
the corresponding channel indicator on
the right side of each key to come on.

DAY key-This key is used to register a
weekly program. Press the key, and
the DAY indicators flash, allowing a

day of the week to be set with the day

setting under each indicator.

TIME key-Press this key to register
the clock program, and the clock

display flashes. Set hours with the

clock settings under the display.

PAUSE key-When it is desirable to stop the clock

operation temporarily on a certain day because that
day falls on a holiday, this can be accomplished by

using this key. After pressing this key (the day
indicators flash), press the desired day setting.

AUTO/OFF switch-Each individual output channel
can be connected and disconnected with this
switch. Setting the switch to ON allows the output
channel of that switch to operate at the programed
time. When set to OFF, the output operation stops.

Output identification label-This
label is supplied with unit. Write

the names of programs of or

equipment connected to each
output channel in the label.

STORE key-Press this key to store the

day of the week or hours set under the
day, time or pause mode.

No programs can be stored in a built-in

memory unless the memory key is
pressed.

CHECK key-This key checks the day of the week or hour for
proper registration. The corresponding date indicator comes
on when checking the day of the week. Also, each time the
CHECK key is pressed, the clock display shows the
programed times from the earliest hour to the latest in

sequence.

CANCEL key-This key cancels the stored day of the
week or hour. To cancel the day of the week, press
the CHECK key to call up the day of the week and
cancel it with the CANCEL key. Similarly, the stored
hour can be cancelled with both the CHECK and

CANCEL keys.

MANUAL switch-Use this switch to

manually deliver the output
regardless of actual program.
Pressing this switch connects a

relay contact for five seconds.

manually activated with this switch

regardless of program as well as
position of the AUTO/OFF switch.

2. This switch cannot be operated

OUTPUT CHANNEL terminal

Output capacity : 24 V DC 0.5 A (resistance load)

Minimum load : 10 mV DC 10µA.

A relay contact connects for five seconds at the

programed time.

These relays are dry contacts.
Connect this terminal to start terminals of BGM
player or spot announcing machine, etc.

AC power inlet

Earth terminal-Be sure to ground unit.

CHANNEL ASSIGNMENT switch-Set each

switch to ON when assigning all of B, C and D

channels to the A channel. When, for example,

the B channel switch is set to ON, the A channel
relay contact connects at the time programed for
both A and B channel. In this event, the B
control output does not work.

MEMORY BACK UP switch-Be sure to set this switch

to ON after installation. This switch protects clock and

stored programs for approximately 100 hours during

power outage.

RACK MOUNTING

SETTING THE CURRENT TIME

1. Plug power cord in wall outlet. Set the program switch to OPERATION. 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 BACKUP switch to ON. The switch allows a clock to work and protects

stored programs during power outage, but no timer output is delivered.

3. Press 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. Pressing 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. Press the 00 SEC. key, while pressing the ADJUST key continuously. This resets the second of a clock to

"00". Pressing 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 OPERATION. Pressing 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.
