Valcom V-AW12A Installation Manual page 11

Installation Option #2 Continued
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 V-AW12A and V-AW16A 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 remove the battery cover, and install two
(2) D cell batteries (recommended battery type: Duracell PROCELL). 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.
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 running. 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 period. Within ten
(10) minutes of Step 1, clock #1 will resume operation and will go to the correct 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 process.
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.
