There are three (3) ways to operate Sapling’s SAL Series Wireless System. The user can
choose any of the combinations listed below, or any combination of the three (3).
Option #1:
There is a main high powered transceiver in the building and repeaters as needed to
cover the entire premise. In this option, the system does not depend on the clock for
transmission.
Option #2:
There is at least one (1) high powered transceiver in the building and in order to cover
the entire premise, the battery operated clocks are used as transceivers/repeaters.
Option #3:
There is at least one (1) high powered transceiver in the building and in order to cover
the entire premise, the power (24V or 110V) operated clocks are used as transceiv-
ers/repeaters.
Operational Instructions
IMPORTANT: We highly recommend installing the main transceiver before the installation
of the SAL Series clocks.
In order to install the clock, simply remove the battery cover, and install two (2) D cell batteries
(recommended battery type: Duracell PROCELL; can be purchased through Sapling (Part # E-
DBATT)). After installation of the battery, replace the battery cover and the clock should start cor-
recting within five (5) minutes.
Normal Mode/Economy Mode
The SAL-2 Series clocks have two different modes in which they will operate. Normal mode allows
the clock to transmit/receive every two (2) hours. This mode will allow the clock to have a 5 year
battery life (provided good reception). Economical mode allows the clock to transmit/receive every
four (4) hours. This mode will allow the clock to have a 8 year battery life (provided good recep-
tion).
Normal mode is defaulted when shipped from the factory.
To toggle this mode, push and release the Diagnostic Switch and the Transmit/Receive switch si-
multaneously. If 5 year mode is selected, the LED will be solid RED for one minute and the second
hand will go to 5 (25 seconds). If 8 year mode is selected, the LED will be solid GREEN for one
minute and the second hand will go to 8 (40 seconds).
IMPORTANT: If a clock is being added to an existing system, it must be in normal mode.

Installation Option #2
There is at least one (1) high powered transceiver in the building and in order to cover the
entire premise, the battery operated clocks are used as transceivers/repeaters.
Clock Operational Overview (Battery Operation Version)
In order to reserve battery consumption, the receiver of the clock is enabled for ten (10)
minutes upon power up. During normal operation, the clock enables its transceiver
every two (2) hours (in normal mode). The clock also has the capability to trans-
mit/receive during normal operation every four (4) hours (in economy mode).
There is a manual option, by pressing the Transmit/Receive switch twice to enable the
receiver for ten (10) minutes in order to receive the time signal. In this case, the second
hand will move to the twenty (20) second location until the signal is received, and then
the clock will resume normal operation.
Operational Instructions
Installation Option #1
There is a main high powered transceiver in the building and high powered transceivers or
repeaters as needed to cover the entire premise. In this option, the system does not depend on
the clock for transmission.
OPTION 1A: Transceivers or repeaters are synchronized wirelessly to the main transceiver.
1. Place the main transceiver in a central location (hallway recommended).
2. Pick the location of the second transceiver or repeater.
3. Place the transceiver/repeater in a location where the signal is available from the main
transceiver. In order to verify that the transceiver is receiving a signal from the main trans-
ceiver, power up the transceiver and within five (5) minutes, it shall show the main trans-
ceiver time. If the transceiver did not correct to the main transceiver time, choose a differ-
ent location for the transceiver.
4. Repeat the above mentioned steps with the corresponding transceivers or repeaters. Please
note that the corresponding transceivers or repeaters can receive a signal from another
transceiver or repeater, and not only from the main transceiver.
OPTION 1B: Transceivers or repeaters are synchronized via wire to the main transceiver.
1. Place the main transceiver in a central location (hallway recommended).
2. Run two (2) conductive wires between the main transceiver and the corresponding trans-
ceivers or repeaters in order to transmit the time between the units.

Option 2A
Go to the nearest clock (clock #1) that has received correction and press the Transmit/Receive
switch once. The second hand should move to forty (40) seconds, and the clock should stop run-
ning. This is an indication that the clock is in transmission mode.
1. Go to the clock (clock #2) that did not receive transmission, and press the Transmit/Receive
switch twice. The second hand should move to twenty (20) seconds until the clock receives
signal from clock #1. Then clock #2 will display the master time within a five (5) minute pe-
riod. Within ten (10) minutes of Step 1, clock #1 will resume operation and will go to the cor-
rect time.
2. Continue with the same process with all of the other clocks. Please note while one (1) clock is
transmitting, you are not limited to the number of clocks that can go through the Step 2 proc-
ess.
When moving further from the transceiver, you can repeat Step 1 and Step 2 using the clock that
most recently received signal.
Option 2B (This option does not test that the distances between the clocks are sufficient)
1. Install the batteries in the clocks in the same area as the main transceiver.
2. After the clock has received signal from the transceiver and adjusted to the main transceiver
time, place the battery cover on.
3. Take each clock, while running, to its designated area and install the clock.
Operational Instructions
There is another manual option, by pressing the Transmit/Receive switch once, to enable the clock
transceiver for ten (10) minutes in order to transmit the time signal. The transceiver can be enabled
only if the clock receives a time signal within the last twelve (12) hours. In this case, the second
hand will move to the forty (40) second location, and after ten (10) minutes, the clock will resume
normal operation.
IMPORTANT: We highly recommend installing the main transceiver before the installation
of the SAL Series clocks.
The transceiver should be located in a central location, preferably in a hallway, so that there are a
minimum number of walls between the transceiver and the clocks. After the installation of the
transceiver, begin installing the clocks nearest to the transceiver; continue installing remaining
clocks working from the transceiver as the central point. In order to install the clock, simply re-
move the battery cover, and install two (2) D cell batteries (recommended battery type: Duracell
PROCELL; can be purchased through Sapling (Part # E-DBATT)). After installation of the battery,
replace the battery cover and the clock should start correcting within five (5) minutes. If correction
is not received within the first five (5) minutes, please follow these instructions. The steps on the
following pages are recommended in order to synchronize the clock system for the first time. The
steps are critical due to the fact that the clock receives and transmits every two (2) hours.
Installation Option #2 (continued)

Installation Option #4
This option allows the user to use multiple transmitters on a campus-like environment.
If a situation arises where the need is to have multiple buildings be synchronized with the wire-
less system, there are two options.
Option 4a
There is one transmitter and the clocks or repeaters send the signal to the other buildings.
This option is when the transmitter or the clocks are in range to the repeater in the other build-
ings. If the transmitter reaches the repeaters or clocks in the other building(s), the clocks will
correct off of the repeater’s transmission of the signal.
Option 4b
There is a transmitter in each building.
Operational Instructions
Installation Option #3
There is at least one (1) high powered transceiver in the building in order to cover the entire prem-
ises. The power (24V or 110V) operated clocks are used as transceivers/repeaters.
Clock Operational Overview (Power Operation 24V or 110V Version)
The clock enables its receiver for ten (10) minutes upon power up and during normal opera-
tion every minute. The clock also has the capability to transmit every minute during normal
operation or during power up once data is received.
We highly recommend installing the main transceiver before the installation of the SAL
Series clocks. The transceiver should be located in a central location preferably in a hallway
so that there are a minimum number of walls between the transceiver and the clock. After the
installation of the transceiver, begin installing the clocks nearest to the transceiver; continue
installing remaining clocks working from the transceiver as the central point. In order to in-
stall the clock, simply connect power to the clock using our pigtail connector.

Frequently Asked Questions
What battery size do I use for the wireless clock?
The batteries required are two (2) “D” cell battery. The recommended battery type is “Duracell:
Procell [D] size”.
Will the clock cause interference with any of my other wireless devices?
No, the SAL Series wireless clock works on 915 - 928 MHz frequency-hopping technology. The
clock switches frequencies automatically when the receiver and transceiver is open, thus interfer-
ence is avoided.
Is there any advantage to a powered clock system as opposed to a battery operated system,
assuming a single transceiver is in the building?
The powered wireless clock receives and transmits every minute and in locations where the signal is
marginal, the likelihood of receiving a signal increases because of the frequent transmission rate.
What is the advantage of having multiple transceivers on a powered clock system?
Assuming the distances between the clocks is sufficient to receive the signal with an analog clock,
there is no advantage of multiple transceivers on a powered system.
How long does it take for the clock to receive a signal?
Upon power up of the clock, the receiver will be turned on for a ten (10) minutes until the signal is
acquired. If the user wishes to manually look for the signal, press the Transmit/Receive switch
twice on the movement.
Can the clocks be set manually to display the correct time at installation (as a temporary measure
until the master clock is installed)?
SAL clocks can NOT be set manually.

What happens if I power up the clock and the clock is not moving?
The clock should move at normal speed upon power up. If it does not move at normal speed, check the
battery and make sure the clock receives power. Also, be sure to remove the pin prior to starting up the
clock. If the clocks are 24 volt or 110 volt, please verify the wiring on page 4 of this manual.
What happens if the clock does not receive the signal?
Take the clock within close proximity to the transceiver and power up the clock. If the clock is battery
operated, remove the battery and put the battery back in again.
Also, press the Transmit/Receive switch once on the clock closest to the clock that isn’t working. The
second hand will go to 8 notifying the user that the clock is transmitting the signal. Then go to the
clock that isn’t working and press the Transmit/Receive switch twice. The second hand will go to 4
notifying the user it is looking for the signal. This should get the signal to the clock.
If the clock does not correct, call Sapling technical support.
What happens if the clock shows the wrong time?
Move the clock to Diagnostic #1 in order to find the last time that it received the signal.
Perform a Diagnostic #3 to check the gears for the clock.
How do you know if the clock receives a good signal?
Perform Diagnostic #2. See page 12 for detailed instructions.
I have a location with a marginal signal. What should I do?
a. Try to install the transceiver in a nearby area.
b. If budget is an issue, install one (1) powered clock.
What can I do if I have a clock in a location where the distance is too far away from the last
clock?
Install a repeater to give additional distance to the clock system.
